Linux Centos7.3 开机启动 Nginx服务

1.正确安装Nginx 

2.编辑nginx的开机启动脚本

vi /etc/init.d/nginx

脚本内容如下 

#!/bin/sh
# chkconfig: 2345 80 90  
# description: Start and Stop nginx

#PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

DESC="nginx daemon"
NAME=nginx
DAEMON=/work/nginx/nginx-1.11.9/sbin/$NAME
CONFIGFILE=/work/nginx/nginx-1.11.9/conf/$NAME.conf
PIDFILE=/work/nginx/nginx-1.11.9/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME

set -e
[ -x "$DAEMON" ] || exit 0

do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}

do_stop() {
kill -INT `cat $PIDFILE` || echo -n "nginx not running"
}

do_reload() {
kill -HUP `cat $PIDFILE` || echo -n "nginx can't reload"
}

case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
reload|graceful)
echo -n "Reloading $DESC configuration..."
do_reload
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac

exit 0

其中这些参数根据自己的实际情况修改，然后保存退出 

:wq

3.注册系统服务

chkconfig --add nginx

4.测试服务

service nginx start

service nginx stop

5.设置开机自启动

chkconfig nginx on

6.关机重启测试

reboot

附：

可执行 ps -ef | grep nginx 查询nginx 是否运行起来

可执行 chkconfig --list 查询nginx 服务在不同运行级的状态,必须在 2345
为 on, 脚本的第二行代码已经设置了
