启动nginx出现问题Failed to start nginx.service:unit not found

 需要手动添加nginx配置服务

根目录运行vim /etc/init.d/nginx

里面插入:

#!/bin/sh
 
# nginx - this script starts and stops the nginx daemin
 
#
 
# chkconfig:   - 85 15
 
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
 
#               proxy and IMAP/POP3 proxy server
 
# processname: nginx
 
# config:      /usr/local/nginx/conf/nginx.conf
 
# pidfile:     /usr/local/nginx/logs/nginx.pid
 
# Source function library.

# Source networking configuration.

# Check that networking is up.
 
[ "$NETWORKING" = "no" ] && exit 0

esac

下面时操作：

cd /etc/init.d
chmod 755 /etc/init.d/nginx
chkconfig --add nginx

systemctl start nginx

systemctl status nginx
