我已经更新了CentOS 7，现在nginx不会在系统启动时自动启动

我已经通过命令“yum update”更新了我的服务器的操作系统（CentOS 7），现在NGINX在系统启动时不启动。

在启动日志显示：

奇怪的是，我可以启动后手动启动NGINX，并且工作正常。

CentOS 7.4.1708

• 在Centos 7上更改Apache 2.4.x的日志文件目录
• 将CentosjoinAD：目录服务无法分配相对标识符
• 在CentOS 7上运行fail2ban，并得到“ssh连接被拒绝”
• 木偶大师的变化并不总是立即被木偶代理人承认
• centOS 7 firewallD删除直接规则
