LAMP-apache编译安装
apache编译安装笔记系统环境：Centos6.664位
apache版本2.4.23
下载apache文件http://httpd.apache.org/download.cgi#apache24
一、准备工作：
先安装依赖组件pcre和openssl-devel
yum -y install pcre-devel
yum -y install openssl-devel
下载、安装apr和apr-util组件
apr下载地址：http://apr.apache.org/download.cgi
1.安装apr
tar xf apr-1.5.2.tar.bz2
cdapr-1.5.2
./configure --prefix=/usr/local/apr #指定安装路径为/usr/local/apr
make
make install
2.安装apr-util
tar xf apr-util-1.5.4.tar.bz2
cd apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make
make install
#指定安装路径：--prefix=/usr/local/apr-util
#告知软件所依赖的apr的安装路径：--with-apr=/usr/local/apr
二、安装httpd
#tar xf httpd-2.4.23.tar.bz2
#cd httpd-2.4.23
#./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd--enable-so --enable-rewirte --enable-ssl --enable-cgi --enable-cgid --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=all --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util--with-mpm=event
#make
#make install
安装完成！
# 各编译参数详解
--prefix：#安装路径
--sysconfdir：#指定配置文件路径
--enable-so：#DSO兼容，DSO=Dynamic Shared Object，动态共享对象，可实现模块动态生效
--enable-ssl：#支持SSL/TLS，可以实现https访问
--enable-cgi：#支持CGI脚本（默认对非线程的MPM模式开启）
--enable-rewrite：#启用Rewrite功能
--enable-deflate：#支持压缩
--with-z：#使用指定的zlib库，不指定路径会自动寻找
--with-pcre：#使用指定的PCRE库，不指定路径会自动寻找
--with-apr：#指定apr安装路径
--with-apr-util：#指定apr-util安装路径
--enable-modules：#支持动态启用的模块，可选参数有“all”，“most”，“few”，“reallyall”
--enable-mpms-shared：#支持动态加载的MPM模块，可选“all”
--with-mpm：#设置默认启用的MPM模式
httpd的MPM有：prefork,worker,event
httpd2.4编译安装的默认MPM为:event
三、启用之前需要配置：
启动httpd之前必须先关闭：selinux
使用：getenforce 查看状态
Enforcing
使用：setenforce 0 关闭
保持状态为Permissive即可：# getenforce
Permissive
使用vim /etc/selinux/config
将SELINUX=permissive
添加主机名称：
在配置文件:/etc/httpd/httpd.conf 里面添加
ServerName localhost:80
在/usr/local/apache/目录下，使用bin/apachectl start启动
关闭防火墙：service iptables stort即可访问。
更改pid文件目录：
修改vim /etc/httpd/httpd.conf
添加:#PidFile "/var/run/httpd.pid" 先用#注释这条命令
使用root@localhost apache]# bin/apachectl stop #关闭apachectl
使用：# netstat -tnlp #验证80端口是否关闭
成功关闭之后进入vim /etc/httpd/httpd.conf把之前注释的命令启用
查看ls /var/run/ 文件夹是否有httpd.pid文件
启动，停止设置：
创建编辑文件：vim /etc/init.d/httpd
写入内容：
#/etc/init.d/httpd文件
#!/bin/bash
#
# httpd Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15

# server implementing the current HTTP standards.

exit $RETVAL
给该文件添加执行权限：chmod +x /etc/init.d/httpd
使用命令：service httpd restart即可重启
开机自动启动：
chkconfig --add httpd #加入服务列表
chkconfig --list httpd #查看默认状态
chkconfig --httpd on #更改状态
启用httpd自带命令：
新建文件： vim/etc/profile.d/httpd.sh
写入内容：export PATH=$PATH:/usr/local/apache/bin
使用命令验证：echo $PATH
更改MPM模块：
编辑：vim/etc/httpd/httpd.conf
默认使用的是event模块：LoadModule mpm_event_module modules/mod_mpm_event.so
使用httpd -M #查看默认使用的模块
打开/etc/httpd/extra/httpd-mpm.conf可配置mpm
