Nginx 编译，添加未编译安装模块ngx_cache_purge

，添加未编译安装模块ngx_cache_purge

1. 官网下载nginx及第三方ngx_cache_purge 模块
   http://wiki.nginx.org/Install
   http://labs.frickle.com/nginx_ngx_cache_purge/
2. 编译与安装
   

Blockquote
./configure \
–prefix=/usr/local/nginx-1.8.0 \
–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=/apps/svr/ngx_cache_purge-2.3

3.为init.d 提供脚本

#!/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.为脚本赋予权限：

chmod +x /etc/init.d/nginx

5.开机启动

chkconfig --add nginx
chkconfig nginx on 
chkconfig nginx --list

6.配置nginx cache 和ngx_cache_purge，如果遇到404，注意proxy_cache_key 和proxy_cache_purge 的配置

proxy_cache_path /data/nginx/cache levels=1:2 keys_zone=cache_one:200m inactive=15d max_size=100g;
    proxy_cache_key  "$request_uri";
    proxy_cache cache_one;
    proxy_cache_valid 200 15d;
    expires 15d;
=============================================
    #仅允许本地网络清理缓存
        location ~ /purge(/.*) {
        allow   106.2.214.50;
        allow   127.0.0.1;
        allow   192.168.5.0/24;
        deny    all;
                proxy_cache_purge   cache_one   $1$is_args$args;
        }
