CentOS7下配置nginx开机自启

1. 创建nginx自动启动命令脚本

vi /etc/init.d/nginx

2.插入以下内容

注意修改PATH和NAME字段, 匹配自己的安装路径 。

PATH=/usr/local/nginx
DESC="nginx daemon"
NAME=nginx
DAEMON=$PATH/sbin/$NAME
COnFIGFILE=$PATH/conf/$NAME.conf
PIDFILE=$PATH/logs/$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() {
    $DAEMON -s stop || echo -n "nginx not running"
}
do_reload() {
    $DAEMON -s reload || 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

3 设置执行权限

chmod a+x /etc/init.d/nginx

4.注册成服务

chkconfig --add nginx

5.设置开机启动

chkconfig nginx on

6. 重启, 查看nginx服务是否自动启动

shutdown -h 0 -r
netstat -apn|grep nginx

7.对nginx服务执行停止/启动/重新读取配置文件操作

启动nginx服务

systemctl start nginx.service

停止nginx服务

systemctl stop nginx.service

重启nginx服务

systemctl restart nginx.service

重新读取nginx配置(这个最常用, 不用停止nginx服务就能使修改的配置生效)

systemctl reload nginx.service
