Linux / centos7使用yum安裝nginx

實驗環境centos7，ip：192.168.9.101

1、首先配置Nginx的yum源，使用vim命令新建nginx.repo文件並寫入內容如下

[root@localhost ~]# vim /etc/yum.repos.d/nginx.repo
##內容如下：
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key

 2、安裝nginx

[root@localhost ~]# yum install -y nginx
已加載插件：fastestmirror
nginx-stable                                                                                         | 2.9 kB  00:00:00

3、啓動nginx，使用netstat -ntlp命令查看端口進程已啓用

[root@localhost ~]# service nginx start
Redirecting to /bin/systemctl start nginx.service
[root@localhost ~]# netstat -ntlp

4、臨時關閉防火牆並使用網頁瀏覽訪問

[root@localhost ~]# systemctl stop firewalld.service

在同一網段的主機瀏覽器上輸入：192.168.9.101進行訪問或做net映射
