使用容器方式的Nginx非常方便，但是这种方式需要Docker运行环境的支持，所以在有些情况下直接在物理机器上安装和设定Nginx的方式仍然非常方便。这篇文章进行一下相关的基础介绍。
安装命令
CentOS/RHEL安装命令: yum install nginx
注意：此安装包目前在epel-release下，所以需要先行安装epel-release。
Ubuntu安装命令: apt install nginx
安装
事前环境确认
[root@liumiaocn ~]# uname -a
Linux liumiaocn 5.4.2-1.el7.elrepo.x86_64 #1 SMP Wed Dec 4 17:32:23 EST 2019 x86_64 x86_64 x86_64 GNU/Linux
[root@liumiaocn ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@liumiaocn ~]#
安装
执行如下命令即可完成安装
步骤1: yum install epel-release -y
步骤2: yum install nginx -y
版本确认
[root@liumiaocn ~]# nginx -v
nginx version: nginx/1.16.1
[root@liumiaocn ~]#
启动nginx服务
启动命令: systemctl start nginx
配置信息确认
使用nginx -V即可确认详细的配置信息，比如本文示例的配置信息如下所示
[root@liumiaocn ~]# nginx -V
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)

[root@liumiaocn ~]#
从上述内容中可以看到一些配置与设定以及此nginx的模块
- 二进制文件：/usr/sbin/nginx
- 安装目录：/usr/share/nginx
- 配置文件目录：/etc/nginx
- 配置文件：/etc/nginx/nginx.conf
- 访问日志信息：/var/log/nginx/access.log
- 错误日志信息：/var/log/nginx/error.log
- 模块保存目录：/usr/lib64/nginx/modules
结果确认
缺省启动后服务会在80端口启动，所以直接使用http://IP或者域名的方式即可直接访问，访问后可以看到如下内容：
这个原因是因为此epel-release下的index.html已经被修改了
[root@liumiaocn ~]# cd /usr/share/nginx/html/
[root@liumiaocn html]# grep 'CentOS' index.html

[root@liumiaocn html]#
正常出现此页面，则能说明在CentOS下的nginx的安装和启动已经正常。
