Apache二进制免编译安装和参数配置

1. 下载http相关二进制软件包

   cd /usr/local/src/
   wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.4.34.tar.gz
   wget http://mirrors.cnnic.cn/apache/apr/apr-1.6.3.tar.gz
   wget http://mirrors.cnnic.cn/apache/apr/apr-util-1.6.1.tar.gz

   说明：
   apr和apr-util是一个通用的函数库，它让httpd可以不关心底层的操作系统平台，可以很方便的从linux移植到windos

2.解压安装包

tar zxvf  httpd-2.4.34.tar.gz
tar zxvf apr-1.6.3.tar.gz
tar zxvf  apr-util-1.6.1.tar.gz

3.编译安装 apr-1.6.3

cd apr-1.6.3
./configure --prefix=/usr/local/apr

报错01：

[root@server-1 apr-1.6.3]# ./configure --prefix=/usr/local/apr
checking build system type... x86_64-pc-linux-gnu

See `config.log' for more details
[root@server-1 apr-1.6.3]# echo $?
1

解决办法：安装gcc

yum install gcc -y

再次config编译成功

[root@localhost apr-1.6.3]# ./configure --prefix=/usr/local/apr

[root@server-1 apr-1.6.3]#make && make install
[root@server-1 apr-1.6.3]# echo $?
0

4.编译安装apr-util-1.6.1

cd /usr/local/src/apr-util-1.6.1
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make && make install

编译安装报错


解决报错：安装expat库

yum install expat-devel -y

再次执行make && make install,报错解决

5.编译安装httpd-2.4.29

cd /usr/local/src/httpd-2.4.29
./configure \
--prefix=/usr/local/apache2.4 \
--with-apr=/usr/local/apr\
--with-apr-util=/usr/local/apr-util \
--enable-so \   ##支持动态扩展模块，apache支持以一个动态模块存在，Apache本身就是一个进程服务
--enable-mods-shared=most

编译报错01:configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

解决办法:
yum install pcre-devel -y

再次执行./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most返回如下界面,表示configure编译成功

注:如果在编译过程中出现，缺少某个依赖包，解决思路
yum list |grep 包
然后安装devel关键字的软件包
yum install -y 软件包

make && make install 编译安装报错

说明：缺少了xml相关的库，需要安装libxml2-devel包。直接安装并不能解决问题，因为httpd调用的apr-util已经安装好了，但是apr-util并没有libxml2-devel包支持
解决办法：

参考https://blog.csdn.net/MrDing991124/article/details/78829184

重新安装libxml2-devel

yum install -y libxml2-devel

删除apr-util软件包

rm -rf /usr/local/src/apr-util-1.6.1
cd /usr/local/src/

重新编译安装apr-util

tar zxvf apr-util-1.6.1.tar.gz
cd apr-util-1.6.1/
 ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make && make install

[root@localhost apr-util-1.6.1]# pwd
/usr/local/src/apr-util-1.6.1
[root@localhost apr-util-1.6.1]# cd ..
[root@localhost src]#
[root@localhost src]# cd httpd-2.4.34
[root@localhost httpd-2.4.34]#
[root@localhost httpd-2.4.34]# ./configure --prefix=/usr/local/apache2.4 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-mods-shared=most
返回下面界面说明configure这步编译成功

make && make install
返回下面界面说明make && make install 执行成功

root@server-1 httpd-2.4.29]# cd /usr/local/apache2.4/
[root@server-1 apache2.4]# ls
bin  build  cgi-bin  conf  error  htdocs  icons  include  logs  man  manual  modules
说明：
bin目录：命令执行
conf目录：配置文件所在目录
htdocs目录：默认网站访问的内容就存在这个目录下
logs日志目录：访问日志，服务报错日志
modules目录：存放apache需要的模块
[root@server-1 apache2.4]# ls ./modules/

[root@server-1 apache2.4]# ls ./htdocs/
index.html
[root@server-1 apache2.4]# ls ./bin/

[root@server-1 apache2.4]# ls ./logs/
[root@server-1 apache2.4]# ls ./conf/
extra  httpd.conf  magic  mime.types  original

查看apache服务状态，执行/usr/local/apache2.4/bin/apachectl命令后返回如下提示

[root@localhost apache2.4]# /usr/local/apache2.4/bin/apachectl
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message

解决办法:
编译/usr/local/apache2.4/conf/httpd.conf文件,把参数 ServerName改为

ServerName localhost

注意:这里的localhost表示本机主机名,主机名可以自定义为其他
然后重启apache服务

[root@localhost src]# /usr/local/apache2.4/bin/apachectl restart
[root@localhost src]# /usr/local/apache2.4/bin/apachectl
httpd (pid 71429) already running

查看apache加载的模块

/usr/local/apache2.4/bin/httpd -M

说明: apache会加载两种类型的模块
static:静态模块
shared：动态模块
两者的区别在于，static模块是已经编译安装到/usr/local/apache2.4/bin/httpd配置文件中，而shared表示apache动态加载的模块

启动apache服务

/usr/local/apache2.4/bin/apachectl start

查看apache服务进程
