nginx：Failed to start nginx.service:unit not found - 知乎 (zhihu.com)

錯誤的原因就是沒有添加nginx服務，所以啓動失敗。

解決方法：

1. 在/root/etc/init.d/目錄下新建文件，文件名爲nginx

　　或者用命令在根目錄下執行:# vim /etc/init.d/nginx (注意vim旁邊有一個空格)

2. 插入以下代碼

#!/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.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ "$NETWORKING" = "no" ] && exit 0

        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2

esac

3. 用命令進入此目錄

cd /etc/init.d

4. 依此執行以下命令

chmod 755 /etc/init.d/nginx

chkconfig --add nginx (注意add前面是兩個短橫線-)

chkconfig nginx on //後執行，此句必須執行，不然沒法自啓動

5. 測試nginx

service nginx start 啓動
service nginx restart 重啓
service nginx stop 停止
