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：[[email protected] 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[email protected] apache]# bin/apachectl stop   #关闭apachectl

使用：[[email protected] 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

# description: The Apache HTTP Server is an efficient and extensible  \

#       server implementing the current HTTP standards.

# processname: httpd

# config: /etc/httpd/conf/httpd.conf

# config: /etc/sysconfig/httpd

# pidfile: /var/run/httpd/httpd.pid

#

### BEGIN INIT INFO

# Provides: httpd

# Required-Start: $local_fs $remote_fs $network $named

# Required-Stop: $local_fs $remote_fs $network

# Should-Start: distcache

# Short-Description: start and stop Apache HTTP Server

# Description: The Apache HTTP Server is an extensible server 

#  implementing the current HTTP standards.

### END INIT INFO

# Source function library.

. /etc/rc.d/init.d/functions   #读取函数

if [ -f /etc/sysconfig/httpd ]; then   #判断该目录下如有httpd文档（配置文件）

        . /etc/sysconfig/httpd          #读到该目录下

fi

# Start httpd in the C locale by default.

HTTPD_LANG=${HTTPD_LANG-"C"}   #如果该变量有值HTTPD_LANG就用原来的值，没有就用"C"的值  

# 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

# work correctly with a thread-based MPM; notably php will refuse to start.

# Path to the apachectl script, server binary, and short-form for messages.

apachectl=/usr/local/apache/bin/apachectl    #定义apachectl程序文件路径

httpd=${HTTPD-/usr/local/apache/bin/httpd}    #定义httpd程序文件路径

prog=httpd

pidfile=${PIDFILE-/var/run/httpd.pid}    #pid文件路径，也就是上一步定义的路径

lockfile=${LOCKFILE-/var/lock/subsys/httpd}   #锁文件

RETVAL=0

STOP_TIMEOUT=${STOP_TIMEOUT-10}

# The semantics of these two functions differ from the way apachectl does

# things -- attempting to start while running is a failure, and shutdown

# when not running is also a failure.  So we just do it the way init scripts

# are expected to behave here.

start() {

        echo -n $"Starting $prog: "

        LANG=$HTTPD_LANG daemon --pidfile=${pidfile} $httpd $OPTIONS

        RETVAL=$?

        echo

        [ $RETVAL = 0 ] && touch ${lockfile}

        return $RETVAL

}

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

# before SIGKILLing the httpd parent; this gives enough time for the

# httpd parent to SIGKILL any errant children.

stop() {

status -p ${pidfile} $httpd > /dev/null

if [[ $? = 0 ]]; then

echo -n $"Stopping $prog: "

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

else

echo -n $"Stopping $prog: "

success

fi

RETVAL=$?

echo

[ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}

}

reload() {

    echo -n $"Reloading $prog: "

    if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then

        RETVAL=6

        echo $"not reloading due to configuration syntax error"

        failure $"not reloading $httpd due to configuration syntax error"

    else

        # Force LSB behaviour from killproc

        LSB=1 killproc -p ${pidfile} $httpd -HUP

        RETVAL=$?

        if [ $RETVAL -eq 7 ]; then

            failure $"httpd shutdown"

        fi

    fi

    echo

RETVAL=2

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
