Centos5.5上搭建LNMP

CentOS-5.5-x86_64+Nginx+php（Fast-cgi）+mysql+memcache+eaccelerator生產環境中的安裝

 

說明：這篇博客和上一篇使用Redhat 系統上做的有很多類似的地方，包括軟件，只是在做的時候遇到的不同問題以及各個問題的解決是這篇博客的最重要的地方

！

實驗環境：

系統：CentOS-5.5-x86_64
# uname -a
Linux centos 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux
# uname -n
centos
# uname -r
2.6.18-194.el5

一、從軟件的官方網站下載軟件包：
[root@centos ~]#mkdir -p lnmp
[root@centos ~]#cd lnmp
wget http://sysoev.ru/nginx/nginx-0.8.46.tar.gz          
wget http://www.php.net/get/php-5.2.14.tar.gz/from/this/mirror

wget http://mynginx.googlecode.com/files/ImageMagick.tar.gz
wget http://lnmpp.googlecode.com/files/imagick-2.3.0.tgz

二、安裝PHP 5.2.14（FastCGI模式）
1、編譯安裝PHP 5.2.14所需的支持庫：

tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../

tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
yum install gcc gcc-c++ gcc-g77 autoconf automake flex bison bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel

 -y
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../

tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install

cd ../

 

做必要庫的鏈接
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4

ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../

安裝mysql
mkdir -pv /mydata/data
tar xf mysql-5.1.46-linux-i686-glibc23.tar.gz  -C /usr/local/
/usr/sbin/groupadd  -g 3306 mysql
/usr/sbin/useradd -g mysql -u 3306 -M -s /sbin/nologin mysql
/bin/chown  -R mysql:mysql /mydata/
/bin/ln  -sv /usr/local/mysql-5.1.46-linux-i686-glibc23  /usr/local/mysql
cd /usr/local/mysql
chown -R　 root:mysql  .
scripts/mysql_install_db --user=mysql --datadir=/mydata/data
cp support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
cp support-files/my-large.cnf /etc/my.cnf
export PATH=$PATH:/usr/local/mysql/bin
echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
/sbin/ldconfig
ln -sv /usr/local/mysql/include    /usr/include/mysql
echo "MANPATH  /usr/local/mysql/man"    >> /etc/man.conf
ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql
service mysqld restart
cd /root/lnmp/

2、編譯安裝PHP（FastCGI模式）
tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
yum install   libxml2-devel  openssl openssl-devel curl curl-devel   openldap openldap-client openldap-devel openldap-servers  libtool-ltdl-devel  ibtool-ltdl  -y
./configure \
--prefix=/usr/local/php  \                                  //指定安裝的位置
--with-config-file-path=/usr/local/php/etc  \   //指定配置文件的位置
--with-mysql=/usr/local/mysql  \               //指定mysql的位置
--with--mysqli=/usr/local/mysql/  \                  
--with-iconv-dir=/usr/local  \                   //指定iconv的位置
--with-freetype-dir  \
--with-jpeg-dir  \                                        //支持jpeg
--with-png-dir  \                                         //支持png

--with-xmlrpc  \
--enable-zip  \
--enable-soap

make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/php/etc/php.ini
cd ../

3、編譯安裝PHP5擴展模塊
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
make
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.6.5-8/
./configure
make
make install
cd ../

tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

4、修改php.ini文件
　　手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"
　　修改爲extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
　　並在此行後增加以下幾行，然後保存：
　　extension = "memcache.so"
　　extension = "pdo_mysql.so"
　　extension = "imagick.so"
　　再查找output_buffering = Off
　　修改爲output_buffering = On
　　再查找 ; cgi.fix_pathinfo=0
　　修改爲cgi.fix_pathinfo=0，即取消註釋，使生效，防止Nginx文件類型錯誤解析漏洞。
　　自動修改：若嫌手工修改麻煩，可執行以下shell命令，自動完成對php.ini文件的修改：
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension =

"memcache.so"\nextension ="pdo_mysql.so"\nextension = "imagick.so"\n#'  /usr/local/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/php/etc/php.ini
sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/php/etc/php.ini

6、配置eAccelerator加速PHP：
mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/php/etc/php.ini
按shift+g鍵跳到配置文件的最末尾，加上以下配置信息：
引用
[eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
7、創建www用戶和組，以及供blog.lamphelp.org和www.lamphelp.org兩個虛擬主機使用的目錄：
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog

8、創建php-fpm配置文件（php-fpm是爲PHP打的一個FastCGI管理補丁，可以平滑變更php.ini配置而無需重啓php-cgi）：
在/usr/local/php/etc/目錄中創建php-fpm.conf文件：
rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf
輸入以下內容（如果您安裝 Nginx + PHP 用於程序調試，請將以下的<value name="display_errors">0</value>改爲<value name="display_errors">1</value>，

以便顯示PHP錯誤信息，否則，Nginx 會報狀態爲500的空白錯誤頁）：
<?xml version="1.0" ?>
<configuration>

　　9、啓動php-cgi進程，監聽127.0.0.1的9000端口，進程數爲128（如果服務器內存小於3GB，可以只開啓64個進程），用戶爲www：
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
　　注：/usr/local/php/sbin/php-fpm還有其他參數，包括：start|stop|quit|restart|reload|logrotate，修改php.ini後不重啓php-cgi，重新加載配置文件使用reload。

--------------------------------------------------------------------------------
三、安裝Nginx 0.8.46
1、安裝Nginx所需的pcre庫：
tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/
./configure
make && make install
cd ../

2、安裝Nginx
tar zxvf nginx-0.8.46.tar.gz
cd nginx-0.8.46/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../

3、創建Nginx日誌目錄
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs

4、創建Nginx配置文件
①、在/usr/local/nginx/conf/目錄中創建nginx.conf文件：
rm -f /usr/local/nginx/conf/nginx.conf
vim  /usr/local/nginx/conf/nginx.conf
輸入以下內容：
引用
user  www www;
worker_processes 8;
error_log  /data1/logs/nginx_error.log  crit;
pid        /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll;
  worker_connections 65535;
}
http
{
  include       mime.types;
  default_type  application/octet-stream;
  #charset  gb2312;
     
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 8m;
     
  sendfile on;
  tcp_nopush     on;
  keepalive_timeout 60;
  tcp_nodelay on;
  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;
  gzip on;
  gzip_min_length  1k;
  gzip_buffers     4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_types       text/plain application/x-javascript text/css application/xml;
  gzip_vary on;
  #limit_zone  crawler  $binary_remote_addr  10m;
  server
  {
    listen       80;
    server_name  blog.lamphelp.org;
    index index.html index.htm index.php;
    root  /data0/htdocs/blog;
    #limit_conn   crawler  20;   
                            
    location ~ .*\.(php|php5)?$
    {     
      #fastcgi_pass  unix:/tmp/php-cgi.sock;
      fastcgi_pass  127.0.0.1:9000;
      fastcgi_index index.php;
      include fcgi.conf;
    }
   
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
      expires      30d;
    }
    location ~ .*\.(js|css)?$
    {
      expires      1h;
    }   
    log_format  access  '$remote_addr - $remote_user [$time_local] "$request" '
              '$status $body_bytes_sent "$http_referer" '
              '"$http_user_agent" $http_x_forwarded_for';
    access_log  /data1/logs/access.log  access;
      }
 
  server
  {
    listen  80;
    server_name  status.blog.lamphelp.org;
    location / {
    stub_status on;
    access_log   off;
    }
  }
}

②、在/usr/local/nginx/conf/目錄中創建fcgi.conf文件：
vim  /usr/local/nginx/conf/fcgi.conf
輸入以下內容：
引用
fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

5、啓動Nginx
ulimit -SHn 65535
/usr/local/nginx/sbin/nginx

--------------------------------------------------------------------------------　
四、配置開機自動啓動Nginx + PHP
vim  /etc/rc.local
在末尾增加以下內容：
引用
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start
/usr/local/nginx/sbin/nginx

--------------------------------------------------------------------------------
五、優化Linux內核參數
vim /etc/sysctl.conf
在末尾增加以下內容：
引用
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog =  32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800
#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024  65535

使配置立即生效：
/sbin/sysctl -p

--------------------------------------------------------------------------------
六、在不停止Nginx服務的情況下平滑變更Nginx配置
1、修改/usr/local/nginx/conf/nginx.conf配置文件後，請執行以下命令檢查配置文件是否正確：
/usr/local/nginx/sbin/nginx -t
如果屏幕顯示以下兩行信息，說明配置文件正確：
       the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully
2、平滑重啓：
　　①、對於Nginx 0.8.x版本，現在平滑重啓Nginx配置非常簡單，執行以下命令即可：
/usr/local/webserver/nginx/sbin/nginx -s reload

　　②、對於Nginx 0.8.x之前的版本，平滑重啓稍微麻煩一些，按照以下步驟進行即可。輸入以下命令查看Nginx主進程號：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
　　屏幕顯示的即爲Nginx主進程號，例如：
　　6302
　　這時，執行以下命令即可使修改過的Nginx配置文件生效：
kill -HUP 6302
　　或者無需這麼麻煩，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

--------------------------------------------------------------------------------
七、編寫每天定時切割Nginx日誌的腳本
1、創建腳本/usr/local/nginx/sbin/cut_nginx_log.sh
vi /usr/local/nginx/sbin/cut_nginx_log.sh
輸入以下內容：
引用
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/usr/local/nginx/logs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`

2、設置crontab，每天凌晨00:00切割nginx訪問日誌
crontab -e
輸入以下內容：
引用
00 00 * * * /bin/bash  /usr/local/nginx/sbin/cut_nginx_log.sh

16）

爲php編譯xcache模塊的時候，需要運行phpize
得到了一個錯誤
#/usr/local/php/bin/phpize
Configuring for:
PHP Api Version:         20041225
Zend Module Api No:      20060613
Zend Extension Api No:   220060519
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF
environment variable is set correctly and then rerun this script.
通過安裝 autoconf 可以解決
centos下執行 yum install autoconf 即可
ubuntu下執行 apt-get install autoconf 即可

17）
# /usr/local/php/bin/phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module
修改方法：
[root@centos lnmp]#  cd php-5.2.14ext/
[root@centos ext]# ./ext_skel --extname=my_module
Creating directory my_module
Creating basic files: config.m4 config.w32 .cvsignore my_module.c php_my_module.h CREDITS EXPERIMENTAL tests/001.phpt my_module.php [done].

To use your new extension, you will have to execute the following steps:

1.  $ cd ..
2.  $ vi ext/my_module/config.m4
3.  $ ./buildconf
4.  $ ./configure --[with|enable]-my_module
5.  $ make
6.  $ ./php -f ext/my_module/my_module.php
7.  $ vi ext/my_module/my_module.c
8.  $ make

Repeat steps 3-6 until you are satisfied with ext/my_module/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.

[root@centos ext]# cd my_module/
[root@centos my_module]# vim config.m4
根據你自己的選擇將
dnl PHP_ARG_WITH(my_module, for my_module support,

dnl Make sure that the comment is aligned:
dnl [ --with-my_module Include my_module support])

修改成
PHP_ARG_WITH(my_module, for my_module support,

Make sure that the comment is aligned:
[ --with-my_module Include my_module support])

或者將
dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,

dnl Make sure that the comment is aligned:
dnl [ --enable-my_module Enable my_module support])

修改成
PHP_ARG_ENABLE(my_module, whether to enable my_module support,

Make sure that the comment is aligned:

[ --enable-my_module Enable my_module support])

[root@centos my_module]# vim my_module.c
　　將文件其中的下列代碼進行修改
/* Every user visible function must have an entry in my_module_functions[].
*/
function_entry my_module_functions[] = {
　　　　PHP_FE(say_hello,　　　 NULL)　/* ?添加着一行代碼 */
　　　　PHP_FE(confirm_my_module_compiled,　　　NULL) /* For testing, remove later. */
　　　　{NULL, NULL, NULL}　　　/* Must be the last line in my_module_functions[] */
};
　　在文件的最後添加下列代碼
PHP_FUNCTION(say_hello)
{
　　　　zend_printf("hello sdomain!");
}
再修改：php_sdomain.h
vi  php_sdomain.h
在PHP_FUNCTION(confirm_my_module_compiled ); /* For testing, remove later. */ 這行的下面添加一行：
PHP_FUNCTION(say_hello); /* For testing, remove later. */
　　保存文件退出
　　然後我們就可以在這個目錄下使用上面的命令了
　　/usr/local/php/bin/phpize
　　執行以後會看到下面的
　　[root@ns sdomain]# /usr/local/php/bin/phpize
　　Configuring for:
　　PHP Api Version:　　　　 20020918
　　Zend Module Api No:　　　20020429
　　Zend Extension Api No:　 20050606
　　[root@ns sdomain]#
　　然後執行./configure --with-php-config=/usr/local/php/bin/php-config
　　然後執行make
　    make install
        然後他會把對應的so文件生成放到PHP安裝目錄下面的一個文件夾，並提示在在什麼地方，然後再把裏面的SO文件拷到你存放SO文件的地方
　　即你在php.ini裏面的extension_dir所指定的位置
　　最後一步是你在php.ini文件中打開這個擴展
　　extension=sdomain.so
　　然後
　　重新起動apache

以上錯誤都是在整個編譯安裝遇到的問題，然後結合網上的資料，找到的解決方法，總結到這個地方，希望能幫到大家！
