實驗：編譯安裝httpd-2.4.38
1、下載源碼並解壓縮
[root@centos7 data]#wget http://mirrors.shu.edu.cn/apache//httpd/httpd-2.4.38.tar.bz2

2、 將三個源碼合併
[root@centos7 data]#mv apr-1.6.5 httpd-2.4.38/srclib/apr
[root@centos7 data]#mv apr-util-1.6.1 httpd-2.4.38/srclib/apr-util
[root@centos7 data]#ls httpd-2.4.38/srclib/
apr apr-util Makefile.in
3、 安裝相關包 yum install gcc gcc-c++ glibc glibc-devel pcre-devel openssl-devel expat-devel
4、編譯安裝[root@centos7 httpd-2.4.38]#1、 cd httpd-2.4.38/
./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-included-apr --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork
2、make && make install
configure: summary of build options:
Server Version: 2.4.38
Install prefix: /app/httpd24
C compiler: gcc -std=gnu99
CFLAGS: -g -O2 -pthread
CPPFLAGS: -DLINUX -D_REENTRANT -D_GNU_SOURCE
LDFLAGS:
LIBS:
C preprocessor: gcc -E
此時，爲了避免衝突，我們把本機yum安裝的httpd卸載，不然都走80端口會衝突。
[root@centos7 httpd-2.4.38]#cd /app/
[root@centos7 app]#ls
httpd24
[root@centos7 app]#cd httpd24/
[root@centos7 httpd24]#ls
bin build cgi-bin conf error htdocs icons include lib logs man manual modules
[root@centos7 httpd24]#ls bin/
ab apr-1-config apxs dbmmanage envvars-std htcacheclean htdigest httpd:主配置文件 logresolve
apachectl：系統啓動文件 apu-1-config checkgid envvars fcgistarter htdbm htpasswd httxt2dbm rotatelogs
5、[root@centos7 httpd24]#vim /etc/profile.d/env.sh 將變量寫入文件
PS1="\[\e[1;32m\][\u@\h \W]\\$\[\e[0m\]"
PATH=/app/httpd24/bin:$PATH
[root@centos7 httpd24]#. /etc/profile.d/env.sh
[root@centos7 httpd24]#echo $PATH
/app/httpd24/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
6、嘗試啓動：[root@centos7 httpd24]#apachectl
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using centos7.localdomain. Set the 'ServerName' directive globally to suppress this message
[root@centos7 ~]#ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :::80 :::*
7、因爲配置已經寫入文件中
[root@centos7 ~]#cd /app/httpd24/htdocs/
[root@centos7 htdocs]#ls
index.html
[root@centos7 htdocs]#cat index.html
<html><body><h1>It works!</h1></body></html>
8、此時在進程中顯示是demon服務，我們要把它改爲Apache服務：修改文件
[root@centos7 httpd24]#ls
bin build cgi-bin conf error htdocs icons include lib logs man manual modules
[root@centos7 httpd24]#cd conf
[root@centos7 conf]#ls
extra httpd.conf magic mime.types original
[root@centos7 conf]#vim httpd.conf

9、[root@centos7 conf]#cd /etc/init.d/
[root@centos7 init.d]#ls

準備環境，兩臺主機，100做httpd+php,150做mariadb
1、將安裝包rz到主機：[root@100 ~]#ls
httpd-2.4.37.tar.bz2 apr-1.6.5.tar.bz2 mariadb-10.2.15-linux-x86_64.tar.gz apr-util-1.6.1.tar.bz2 php-7.3.2.tar.xz wordpress-5.0-zh_CN.zip
[root@100 ~]#tar xf apr-1.6.5.tar.bz2
[root@100 ~]#tar xf httpd-2.4.37.tar.bz2
[root@100 ~]#tar xf php-7.3.2.tar.xz
[root@100 ~]#tar xf apr-util-1.6.1.tar.bz2
2、100主機上：mv apr-1.6.5 httpd-2.4.37/srclib/apr
mv apr-util-1.6.1 httpd-2.4.37/srclib/apr-util
3、一、cd httpd-2.4.37/
二、yum install gcc glibc pcre-devel openssl-devel expat-devel libxml2-devel bzip2-devel libmcrypt-devel
三、./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork --with-included-apr
四、make -j 4 && make install
4、[root@100 httpd-2.4.37]#echo 'PATH=/app/httpd24/bin:$PATH' > /etc/profile.d/lamp.sh
[root@100 httpd-2.4.37]#. /etc/profile.d/lamp.sh
5、useradd -r -s /sbin/nologin apache
[root@centos7 httpd-2.4.37]#vim /app/httpd24/conf/httpd.conf 此項修改不是必須，主要爲了方便查看
User apache
Group apache
6、[root@100 httpd-2.4.37]#apachectl
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 0.0.0.100. Set the 'ServerName' directive globally to suppress this message
[root@100 httpd-2.4.37]#ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 :::80 :::*
7、現在我們去centos6上測試：[root@centos6 ~]#curl 192.168.141.100
<html><body><h1>It works!</h1></body></html> 此時說明Apache已經安裝成功。
8、150主機上：tar xvf mariadb-10.2.15-linux-x86_64.tar.gz -C /usr/local/

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:
'./bin/mysqladmin' -u root password 'new-password'
'./bin/mysqladmin' -u root -h centos7.localdomain password 'new-password'
Alternatively you can run:
'./bin/mysql_secure_installation'
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.
You can start the MariaDB daemon with:
cd '.' ; ./bin/mysqld_safe --datadir='/data/mysql'
You can test the MariaDB daemon with mysql-test-run.pl
cd './mysql-test' ; perl mysql-test-run.pl
Please report any problems at http://mariadb.org/jira

現在我們去訪問頁面：
實驗：編譯實現基於FASTCGI的LAMP的wordpress
基於模塊方式安裝使用php
1、yum install php
[root@centos7 ~]#cd /var/www/html
[root@centos7 html]#ls
admin a.txt hello.sh index.html setcookie.php test.html
[root@centos7 html]#vim index.php
<?php
echo date("Y/m/d H:i:s");
phpinfo();
?> 下圖爲動態頁面：
[root@centos7 html]#yum install php-mysql 要連數據庫就要下載該包
3、yum install mariadb-server
[root@centos7 html]#systemctl restart mariadb
4、[root@centos7 html]#mysql_secure_installation 安全加固腳本
5、[root@centos7 html]#vim mysql.php
<?php
try {
$user='root';
$pass='123gxy';
$dbh= new PDO('mysql:host=localhost;dbname=mysql', $user, $pass);
foreach($dbh->query('SELECT user,host from user') as $row) {
print_r($row);
}
$dbh = null;
} catch (PDOException$e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
?>
[root@centos7 html]#systemctl restart mariadb
6、[root@centos7 ~]#mysql -uroot -p123gxy
MariaDB [(none)]> select user,host from mysql.user;
+------+-----------+
| user | host |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1 |
| root | localhost |
+------+-----------+
3 rows in set (0.00 sec)
此時這個實驗就做完了。實驗：php使用PDO擴展連接數據庫
將壓縮包傳到主機並壓縮：
tar xvf phpMyAdmin-4.0.10.20-all-languages.tar.xz
[root@centos7 ~]#cd phpMyAdmin-4.0.10.20-all-languages
[root@centos7 phpMyAdmin-4.0.10.20-all-languages]#pwd
/root/phpMyAdmin-4.0.10.20-all-languages
[root@centos7 phpMyAdmin-4.0.10.20-all-languages]#cd ..
[root@centos7 ~]#ls
！ hellodb_innodb.sql phpMyAdmin-4.0.10.20-all-languages
anaconda-ks.cfg initial-setup-ks.cfg phpMyAdmin-4.0.10.20-all-languages.tar.xz
[root@centos7 ~]#mv phpMyAdmin-4.0.10.20-all-languages /var/www/html/pma
[root@centos7 ~]#cd /var/www/html/pma
[root@centos7 pma]#yum install php-mbstring 安裝這個輔助工具
[root@centos7 pma]#cp config.sample.inc.php config.inc.php
[root@centos7 pma]#vim config.inc.php 此項是修改默認密碼，基於安全。
$cfg['blowfish_secret'] = '123gxy'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
[root@centos7 pma]#systemctl restart httpd
登陸用戶及密碼即可進入圖形化界面：
這時我們已經創建了用戶如下：
[root@centos7 ~]#mysql -uwpuser -p123gxy -h192.168.141.200.
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| wordpress |該用戶已經被創建成功。
+--------------------+
2 rows in set (0.00 sec) 該實驗完成。在網站上訪問及在mysql數據庫查詢結果一致。實驗：部署wordpress
將下載的軟件包傳到主機並解壓
tar xvf wordpress-5.0.3-zh_CN.tar.gz
[root@centos7 ~]#cd wordpress/
[root@centos7 wordpress]#ls
index.php wp-activate.php wp-comments-post.php wp-cron.php wp-load.php wp-settings.php xmlrpc.php
license.txt wp-admin wp-config-sample.php wp-includes wp-login.php wp-signup.php
readme.html wp-blog-header.php wp-content wp-links-opml.php wp-mail.php wp-trackback.php
[root@centos7 wordpress]#cp wp-config-sample.php wp-config.php
[root@centos7 wordpress]#vim wp-config.php
/** WordPress數據庫的名稱 */
define('DB_NAME', 'wordpress');
/** MySQL數據庫用戶名 */
define('DB_USER', 'wpuser');
/** MySQL數據庫密碼 */
define('DB_PASSWORD', '123gxy');
/** MySQL主機 */
define('DB_HOST', '192.168.141.200');
[root@centos7 ~]#mv wordpress /var/www/html/
[root@centos7 ~]#cd /var/www/html/
[root@centos7 html]#ls
admin pma setcookie.php wordpress
下面我們去網站登錄：
成功登陸後的後臺頁面：我們就可以自建博客了：
實驗：源碼編譯php.fpm
1、[root@centos7 ~]#ls
httpd-2.4.37.tar.bz2 apr-util-1.6.1.tar.bz2 apr-1.6.5.tar.bz2
[root@centos7 ~]#mv httpd-2.4.38.tar.bz2 apr-* /data/
[root@centos7 ~]#cd /data/
[root@centos7 data]#ls
apr-1.6.5.tar.bz2 apr-util-1.6.1.tar.bz2 httpd-2.4.38.tar.bz2
tar xvf xxxx 將其三個包解壓：
root@centos7 data]#ls
apr-1.6.5 apr-util-1.6.1 httpd-2.4.38 apr-1.6.5.tar.bz2 apr-util-1.6.1.tar.bz2 httpd-2.4.38.tar.bz2
[root@centos7 data]#mv apr-1.6.5 httpd-2.4.38/srclib/apr
[root@centos7 data]#mv apr-util-1.6.1 httpd-2.4.38/srclib/apr-util
2、[root@centos7 httpd-2.4.38]#1、yum install gcc glibc pcre-devel openssl-devel expat-devel 安裝必要包
[root@centos7 httpd-2.4.38]#./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-included-apr --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork
2、[root@centos7 data]#make && make install
3、[root@centos7 httpd-2.4.38]#cd /app/httpd24/
[root@centos7 httpd24]#ls

4、現在去另一主機上curl一下：[root@centos7 ~]#curl 192.168.141.200
<html><body><h1>It works!</h1></body></html>
5、 yum install php-fpm php-mysql mariadb-server 安裝必要的包
6、一、[root@centos7 bin]#vim /app/httpd24/conf/httpd.conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so 這2項取消註釋，使之生效。
user apache
Group apache
</IfModule>
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
ProxyRequests Off
ProxyPassMatch "^/(.*\.php(/.*)?)$" "unix:/var/run/php-fpm.sock|fcgi://localhost/app/httpd24/htdocs/" 這是指定套接字的路徑
二、[root@centos7 bin]# vim /etc/php-fpm.d/www.conf
;listen = 127.0.0.1:9000
listen=/var/run/php-fpm.sock
listen.mode = 0666
