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
?
| 1 2 | [root@localhost ~] # cat /etc/redhat-release CentOS 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：
?
| 1 | 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）
?
| 1 2 3 4 5 | [nginx] name=nginx repo baseurl=http: //nginx .org /packages/centos/ $releasever/$basearch/ gpgcheck=0 enabled=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
?
| 1 | 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：
?
| 1 | nginx -t |
打印如下：
?
| 1 2 | nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful |
说明配置文件成功！
centos7.0+ nginx实现停止、启动、重启
在CentOS7中，进行chkconfig命令操作时会发现有类似“systemctl…..”的提示，systemctl可以简单实现service和chkconfig的结合，这样通过一个命令就可以实现两个命令的功能。
systemctl命令的基本操作格式是：
?
| 1 | systemctl [OPTIONS...] {COMMAND}... |
以nginx服务为例，实现停止、启动、重启的动作如下：
?
| 1 2 3 | systemctl stop nginx.service systemctl start nginx.service systemctl restart nginx.service |
检查服务状态
?
| 1 | systemctl status nginx.service |
使服务开机启动
?
| 1 | systemctl enable nginx.service |
取消服务开机启动
?
| 1 | systemctl disable nginx.service |
