nginx代理服务器的简单实现

发布时间：2014-09-05 16:55:29作者：知识屋

我们要创建一个nginx服务器，代理ip为192.168.0.101，本机作为测试主，本机的ip是192.168.0.234

Nginx代理服务器的配置
首先，配置好yum源
[root@server70 ~]# yum groupinstall -y "Development Tools" "Development Libraries"
[root@server70 ~]# yum install gcc openssl-devel pcre-devel zlib-devel –y
Lftp 192.168.0.254
下载nagios-3.2.1.tar.gz
Tar xf nginx-1.1.3.tar.gz
# groupadd nginx
# useradd -g nginx -s /bin/false -M nginx
#cd nginx-1.1.3
./configure/
--prefix=/usr /
--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/ /
--with-pcre

Make && make install

Vim /etc/init.d/nginx
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

[ "$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
     退出，给/etc/init.d/nginx 执行权限
     Chmod +x /etc/init.d/nginx
     使其开机不能自动启动
     Chkconfig --add nginx

     下面我们可以启动nginx了
      #service nginx start
      然后看一下80端口是否已经启动
     #netstat -tnlp
       [root@server70 ~]# netstat -tnlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address               Foreign Address             State       PID/Program name
tcp        0      0 127.0.0.1:2208              0.0.0.0:*                   LISTEN      2310/hpiod
tcp        0      0 0.0.0.0:111                 0.0.0.0:*                   LISTEN      2000/portmap
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      8448/nginx.conf

可以看见，80端口已经开启
       之后我们可以看一下nginx的测试页，直接输入代理服务器的ip
当出现welcome 几个单词时就表示安装nginx成功，下面只剩配置

       Cd /etc/nginx/
       Cp nginx.conf nginx.conf.bak

       然后在/etc/nginx/nginx.conf 下修改并添加如下内容
       events {
    worker_connections 51200;
}

       server {
        listen       80;
        server_name localhost;

        #charset koi8-r;

        #access_log logs/host.access.log main;

        location / {
            root   /web;
            index index.html index.htm;
        }

         location /bbs {
            root   /web;
            index test.html;
        }
        保存并推出
         分别创建/web/ 和/web/bbs/
         Mkdir /web
         Mkdir /web/bbs
         Echo “hello,are you ok” > / web/index.htm
         Echo “hello” > /web/bbs/test.html
          下面分别访问这两个页面文件，在浏览器中输入：http://192.168.0.101

http://192.168.0.101/bbs

            当然，我们还可以做代理服务网页的访问控制，比如我们这时候对于/web/bbs/test.thml这个网页文件对于测试机可以访问的，下面我们要实现拒绝测试机访问。
            那怎么实现呢，我们需要编辑/etc/nginx/nginx.conf
            location /bbs {
            root   /web;
            index index.html;
            deny 192.168.0.234;#############只拒绝192.168.0.234访问
            allow all; ################允许所有
            保存退出，并重载文件
            重新在测试机上访问/web/bbs/test.html
