LInux系列之Centos源码编译nginx模块purge

上一篇中有回复说源码编译，今天就发一个源码编译NGINX的方法，本系统所有内容都进行过实操

标题写不下，唉，本篇以ngx_cache_purge为例说明

系列目录

1、Linux系列Centos6.7基础系统安装配置

2、Linux系统之Centos更新系统时间以及定时同步网络时间

3、Linux系列之CentOS+Nginx+PHP+MySQL

4、【本篇】LInux系列之Centos6.7源码编译nginx + ngx_cache_purge

========================================================

1. 下载软件包

1.1 下载Nginx

---------------------------------------------------------------------------------

wget http://nginx.org/download/nginx-1.11.4.tar.gz

tar zxvf nginx-1.11.4.tar.gz

---------------------------------------------------------------------------------

1.2 下载缓存清除 模块 ngx_cache_purge

---------------------------------------------------------------------------------

wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz

tar zxvf ngx_cache_purge-2.3.tar.gz

---------------------------------------------------------------------------------

1.3 下载Nginx Image 缩略图 模块 ngx_image_thumb-master

---------------------------------------------------------------------------------

wget https://github.com/3078825/nginx-image/archive/master.zip

unzip master.zip

---------------------------------------------------------------------------------

2. 安装环境依赖包

---------------------------------------------------------------------------------

yum install autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc gd-devel

---------------------------------------------------------------------------------

3. 编译安装

3.1 配置

进入nginx解压目录，同时注意保持ngx_cache_purge与nginx为同级目录（安装模块时指定的目录路径）

---------------------------------------------------------------------------------

./configure \

--prefix=/usr/local/nginx-1.11.4 \

--sbin-path=/usr/sbin/nginx \

--conf-path=/etc/nginx/nginx.conf \

--error-log-path=/var/log/nginx/error.log \

--http-log-path=/var/log/nginx/access.log \

--pid-path=/var/run/nginx/nginx.pid \

--lock-path=/var/lock/nginx.lock \

--user=nginx \

--group=nginx \

--with-http_ssl_module \

--with-http_flv_module \

--with-http_stub_status_module \

--with-http_gzip_static_module \

--http-client-body-temp-path=/var/tmp/nginx/client/ \

--http-proxy-temp-path=/var/tmp/nginx/proxy/ \

--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \

--add-module=../ngx_cache_purge-2.3 \

--add-module=../ngx_image_thumb-master

---------------------------------------------------------------------------------

3.2 编译安装

---------------------------------------------------------------------------------

make & make install

---------------------------------------------------------------------------------

安装好之后，默认的nginx根目录为 /usr/local/nginx

4 配置

4.1 增加nginx用户

---------------------------------------------------------------------------------

groupadd -f nginx

useradd -g nginx nginx

---------------------------------------------------------------------------------

4.2 编写启动脚本

---------------------------------------------------------------------------------

vi /etc/init.d/nginx

#!/bin/sh

#

# nginx - this script starts and stops the nginx daemon

#

# chkconfig: - 85 15

# description: Nginx is an HTTP(S) server, HTTP(S) reverse \

# proxy and IMAP/POP3 proxy server

# processname: nginx

# config: /etc/nginx/nginx.conf

# config: /etc/sysconfig/nginx

# pidfile: /var/run/nginx.pid

# Source function library.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/sbin/nginx"

prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

make_dirs() {

# make required directories

user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`

options=`$nginx -V 2>&1 | grep 'configure arguments:'`

for opt in $options; do

if [ `echo $opt | grep '.*-temp-path'` ]; then

value=`echo $opt | cut -d "=" -f 2`

if [ ! -d "$value" ]; then

# echo "creating" $value

mkdir -p $value && chown -R $user $value

fi

fi

done

}

start() {

[ -x $nginx ] || exit 5

[ -f $NGINX_CONF_FILE ] || exit 6

make_dirs

echo -n $"Starting $prog: "

daemon $nginx -c $NGINX_CONF_FILE

retval=$?

echo

[ $retval -eq 0 ] && touch $lockfile

return $retval

}

stop() {

echo -n $"Stopping $prog: "

killproc $prog -QUIT

retval=$?

echo

[ $retval -eq 0 ] && rm -f $lockfile

return $retval

}

restart() {

configtest || return $?

stop

sleep 1

start

}

reload() {

configtest || return $?

echo -n $"Reloading $prog: "

killproc $nginx -HUP

RETVAL=$?

echo

}

force_reload() {

restart

}

configtest() {

$nginx -t -c $NGINX_CONF_FILE

}

rh_status() {

status $prog

}

rh_status_q() {

rh_status >/dev/null 2>&1

}

case "$1" in

start)

rh_status_q && exit 0

$1

;;

stop)

rh_status_q || exit 0

$1

;;

restart|configtest)

$1

;;

reload)

rh_status_q || exit 7

$1

;;

force-reload)

force_reload

;;

status)

rh_status

;;

condrestart|try-restart)

rh_status_q || exit 0

;;

*)

echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"

exit 2

esac

---------------------------------------------------------------------------------

4.3 添加脚本运行权限

---------------------------------------------------------------------------------

chmod +x /etc/init.d/nginx

---------------------------------------------------------------------------------

4.4 增加开机启动

---------------------------------------------------------------------------------

chkconfig --add nginx

chkconfig nginx on

chkconfig nginx --list

---------------------------------------------------------------------------------

5 配置nginx

5.1 nginx.conf
