linux下nginx安装与设置开机启动

http://www.myhack58.com/Article/sort099/sort0102/2015/66341.htm

• 环境准备

yum -y install gcc gcc-c++ autoconf automake makeyum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel 

• 下载 nginx 、解压、编译并安装

wget  http://nginx.org/download/nginx-1.8.0.tar.gz  tar zxvf nginx-1.8.0.tar.gzcd nginx-1.8.0./configure --prefix=/data/server/nginx  #指定安装目录

或者 ./configure --prefix=/data/server/nginx --with-http_stub_status_module #后面的参数为了支持图形监控插件make && make install

• 启动nginx

/usr/local/nginx/sbin/nginx

此时，可以通过浏览器访问本机ip,会出现如下字段：  

• 开机启动nginx

首先，在linux系统的/etc/init.d/目录下创建nginx文件，使用如下命令：  vi /etc/init.d/nginx  在脚本中添加如下命令：

**********************************************************************************************#!/bin/bash# nginx Startup script for the Nginx HTTP Server# it is v.0.0.2 version.# chkconfig: - 85 15# description: Nginx is a high-performance web and proxy server.#              It has a lot of features, but it's not for everyone.# processname: nginx# pidfile: /var/run/nginx.pid# config: /usr/local/nginx/conf/nginx.confnginxd=/usr/local/nginx/sbin/nginxnginx_config=/usr/local/nginx/conf/nginx.confnginx_pid=/var/run/nginx.pidRETVAL=0prog="nginx"# Source function library.. /etc/rc.d/init.d/functions# Source networking configuration.. /etc/sysconfig/network# Check that networking is up.[ ${NETWORKING} = "no" ] && exit 0[ -x $nginxd ] || exit 0# Start nginx daemons functions.start() {if [ -e $nginx_pid ];then   echo "nginx already running...."   exit 1fi   echo -n $"Starting $prog: "   daemon $nginxd -c ${nginx_config}   RETVAL=$?   echo   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx   return $RETVAL}# Stop nginx daemons functions.stop() {        echo -n $"Stopping $prog: "        killproc $nginxd        RETVAL=$?        echo        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid}# reload nginx service functions.reload() {    echo -n $"Reloading $prog: "    #kill -HUP `cat ${nginx_pid}`    killproc $nginxd -HUP    RETVAL=$?    echo}# See how we were called.case "$1" instart)        start        ;;stop)        stop        ;;reload)        reload        ;;restart)        stop        start        ;;status)        status $prog        RETVAL=$?        ;;*)        echo $"Usage: $prog {start|stop|restart|reload|status|help}"        exit 1esacexit $RETVAL***************************************************************************************

nginxd=/usr/local/nginx/sbin/nginxnginx_config=/usr/local/nginx/conf/nginx.confnginx_pid=/var/run/nginx.pid

接着，设置文件的访问权限：  chmod a+x /etc/init.d/nginx (a+x参数表示 ==> all user can execute 所有用户可执行)

最后将ngix加入到rc.local文件中，这样开机的时候nginx就默认启动了  vi /etc/rc.local  添加  /etc/init.d/nginx start  保存并退出  下次重启就会生效，实现nginx的自启动。
