CentOS7.2安装Nginx的方法步骤

CentOS7.2安装Nginx过程笔记，由于学习的需要，这段时间学一点“nginx”。今天学习一下Nginx安装，留个笔记

查看CentOS的版本

使用一下命令来查看一下当前系统的版本

[root@localhost ~]# cat /etc/redhat-releaseCentOS Linux release 7.2.1511 (Core)

添加资源库

在 CentOS 系统上安装 Nginx ，你得先去添加一个资源库，像这样：

vim /etc/yum.repos.d/nginx.repo

使用 vim 命令去打开 /etc/yum.repos.d/nginx.repo ，如果 nginx.repo 不存在，就会去创建一个这样的文件，打开以后按一下小 i 键，进入编辑模式，然后复制粘贴下面这几行代码，完成以后按 esc 键退出，再输入:wq （保存并退出）

[nginx]name=nginx repobaseurl=http://nginx.org/packages/centos/$releasever/$basearch/gpgcheck=0enabled=1

yum 命令去安装 nginx

完成上边操作以后，我们就可以使用 yum 命令去安装 nginx 了

yum install nginx

安装成功：

测试nginx配置文件

当你执行 nginx -t 得时候，nginx会去测试你得配置文件得语法，并告诉你配置文件是否写得正确，同时也告诉了你配置文件得路径：

nginx -t

打印如下：

nginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful
