apxs是一个为Apache HTTP服务器编译和安装扩展模块的工具，用于编译一个或多个源程序或目标代码文件为动态共享对象，使之可以用由mod_so提供的LoadModule指令在运行时加载到Apache服务器中。

输入命令查看是否有httpd-devel这个包，如果没有需要安装

[root@izbp18dv3a3metugyd02qxz syhuo.dashboard]# yum -y install httpd*
[root@izbp18dv3a3metugyd02qxz syhuo.dashboard]# yum list installed | grep -i 'httpd'
httpd.x86_64                          2.4.6-93.el7.centos             @base     
httpd-devel.x86_64                    2.4.6-93.el7.centos             @base     
httpd-tools.x86_64                    2.4.6-93.el7.centos             @base

 

若apache是选择源码编译安装编译安装加上 --with-apr=/usr/local/apr、--with-apr-util=/usr/local/apr-util，先安装apr，再安装apr-util，apr-util依赖apr

[root@localhost httpd-2.4.41]# cat /root/download/apache2/httpd-2.4.41/config.nice 
#! /bin/sh
#
# Created by configure

"./configure" \
"--prefix=/etc/httpd" \
"--enable-so" \
"--enable-ssl" \
"--enable-cgi" \
"--enable-rewrite" \
"--with-zlib" \
"--with-pcre" \
"--with-apr=/usr/local/apr" \
"--with-apr-util=/usr/local/apr-util" \
"--enable-modeles=most" \
"--enable-mpms-shared=all" \
"--with-mpm=event" \
"$@"

 

以apxs方式安装apache模块，无需再次编译安装apache，以ssl_module为例，需要先安装openssl

cd /root/download/apache2/httpd-2.4.41/modules/ssl

/bin/apxs -a -i -c -L/usr/lib/openssl/engines/lib -c *.c -lcrypto -lssl -ldl
