nginx安装参考：linux centos7环境nginx安装配置

在/etc/init.d/文件夹下创建nginx文件，并写入如下内容：

vi /etc/init.d/nginx

#!/bin/bash  
# nginx Startup script for the Nginx HTTP Server  
#  
# 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.conf 

########### need to modify  the path ###################

# 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 1  
fi  

   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: " 
 $nginxd -s reload  
    #if your nginx version is below 0.8, please use this command: "kill -HUP `cat ${nginx_pid}`" 
    RETVAL=$?  
    echo  

}  

# See how we were called.  
case "$1" in 
start)  
        start  
        ;;  

stop)  
        stop  
        ;;  

reload)  
        reload  
        ;;  

restart)  
        stop  
        start  
        ;;  

status)  
        status $prog  
        RETVAL=$?  
        ;;  
*)  
        echo $"Usage: $prog {start|stop|restart|reload|status|help}" 
        exit 1  
esac  

exit $RETVAL

注意：以下参数要修改成你nginx安装时配置的值

nginxd=/usr/local/nginx/sbin/nginx  
nginx_config=/usr/local/nginx/conf/nginx.conf  
nginx_pid=/var/run/nginx.pid

执行命令：

[root@localhost /]# cd /etc/rc.d/init.d
[root@localhost init.d]# chmod +x nginx
[root@localhost init.d]# /sbin/chkconfig --level 345 nginx on

此时在任何位置都可以运行： service nginx start

可选 start | stop | restart | reload | status | help
