centos 7 nginx 安装
1、下载nginx rpm包
下载地址:http://nginx.org/packages/mainline/centos/7/x86_64/RPMS/ ,可查看所有安装包
从中如下载:
wget http://nginx.org/packages/mainline/centos/7/x86_64/RPMS/nginx-1.11.5-1.el7.ngx.x86_64.rpm
2、安装nginx
rpm -ivh nginx-1.11.5-1.el7.ngx.x86_64.rpm
3、检查是否安装成功
nginx -v
输入此命令后显示nginx版本信息
4、开启服务
查看服务状态命令:systemctl status nginx.service
开启/停止/重启服务命令:systemctl start/stop/restart nginx.service 如开启服务:systemctl start nginx.service
开机启动/取消命令:systemctl enable/disable nginx.service 开机启动:systemctl enable nginx.service
5、查看服务是否正常
打开浏览器,输入地址:http://localhost 会显示nginx欢迎界面
无界面情况下,可以通过telnet loaclhost 80(telnet 127.0.0.1 80) 查看80端口是否开启(telnet没有安装 可以通过yum install telnet),然后输入任意字符比如"d",telnet 窗口返回服务器信息
[root@localhost /]# telnet localhost 80 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. d HTTP/1.1 400 Bad Request Server: nginx/1.11.5 Date: Thu, 03 Nov 2016 02:20:49 GMT Content-Type: text/html Content-Length: 173 Connection: close <html> <head><title>400 Bad Request</title></head> <body bgcolor="white"> <center><h1>400 Bad Request</h1></center> <hr><center>nginx/1.11.5</center> </body> </html> Connection closed by foreign host.
在信息输出http头信息里面含Server: nginx/1.11.5,表示nginx已经提供服务
