CentOS7.2安裝Nginx過程筆記，由于學習的需要，這段時間學一點“nginx”。今天學習一下Nginx安裝，留個筆記

查看CentOS的版本

使用一下命令來查看一下當前系統的版本

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

添加資源庫

在 CentOS 系統上安裝 Nginx ，你得先去添加一個資源庫，像這樣：

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

使用 vim 命令去打開 /etc/yum.repos.d/nginx.repo ，如果 nginx.repo 不存在，就會去創建一個這樣的文件，打開以后按一下小 i 鍵，進入編輯模式，然后復制粘貼下面這幾行代碼，完成以后按 esc 鍵退出，再輸入:wq （保存并退出）

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

yum 命令去安裝 nginx

完成上邊操作以后，我們就可以使用 yum 命令去安裝 nginx 了

yum install nginx

安裝成功：

測試nginx配置文件

當你執行 nginx -t 得時候，nginx會去測試你得配置文件得語法，并告訴你配置文件是否寫得正確，同時也告訴了你配置文件得路徑：

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
