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 make
yum -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.gz
cd 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：

[ -x $nginxd ] || exit 0

start() {

   echo "nginx already running...."

   echo

   return $RETVAL
}

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

case "$1" in
start)
        start
        ;;
stop)
        stop
        ;;
reload)
        reload
        ;;
restart)
        stop
        start
        ;;

        status $prog
        RETVAL=$?
        ;;

        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_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。
