apache编译安装笔记

系统环境:Centos6.6  64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

cd  apr-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:[root@localhost httpd-2.4.23]# 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:[root@localhost apache]# 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.

# processname: httpd

# This will prevent initlog from swallowing up a pass-phrase prompt if

# mod_ssl needs a pass-phrase from the user.

INITLOG_ARGS=""   #这个变量值为空


# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server

# with the thread-based "worker" MPM; BE WARNED that some modules may not

# are expected to behave here.

# When stopping httpd, a delay (of default 10 second) is required

stop() {

if [[ $? = 0 ]]; then

echo -n $"Stopping $prog: "

killproc -p ${pidfile} -d ${STOP_TIMEOUT} $httpd

esac


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
