【已解决】CentOS 7中安装Nginx

折腾：

【已解决】把本地前端页面部署到在线Flask环境中

期间，需要先去到在线的CentOS 7：

[root@xx-general-01 ~]# lsb_release -a

LSB Version: :core-4.1-amd64:core-4.1-noarch

Distributor ID: CentOS

Description: CentOS Linux release 7.4.1708 (Core)

Release: 7.4.1708

Codename: Core

[root@x-general-01 ~]# cat /etc/centos-release

CentOS Linux release 7.4.1708 (Core)

中安装Nginx

[root@xx-general-01 ~]# ll /etc/ng*

ls: cannot access /etc/ng*: No such file or directory

[root@xx-general-01 ~]# ll /usr/local/ngi*

ls: cannot access /usr/local/ngi*: No such file or directory

基本上确定了此处没有CentOS中没有安装nginx

centos install nginx

How To Install Nginx on CentOS 7 | DigitalOcean

CentOS 7 yum 安装 Nginx – CSDN博客

nginx服务器详细安装过程（使用yum 和源码包两种安装方式，并说明其区别） – 傅毅 – SegmentFault 思否

Install | NGINX

看起来还是CentOS中用yum去安装，比较省事和方便。

【总结】

此处CentOS 7.4中，安装nginx，直接用yum去安装：

yum -y install nginx

查看nginx版本：

nginx -h

此处是：nginx/1.12.2

查看配置文件所在目录：

ls -lha /etc/nginx/*

然后启动：

systemctl status nginx

查看状态：

systemctl status nginx

设置开机启动：

systemctl enable nginx

查看是否已设置为开机启动：

systemctl is-enabled nginx
