linux7/centos7通过yum安装nginx

实验环境centos7，ip：192.168.11.123

1、首先配置yum源，使用vim命令新建nginx.repo文件并写入内容如下

[root@localhost ~]# vim /etc/yum.repos.d/nginx.repo
##内容如下：
[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、安装nginx

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

完毕！

3、启动nginx，使用netstat -ntlp命令查看端口进程已启用

[root@localhost ~]# service nginx start
Redirecting to /bin/systemctl start nginx.service
[root@localhost ~]# netstat -ntlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

4、临时关闭防火墙并使用网页浏览访问

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

在同一网段的主机浏览器上输入：192.168.11.123进行访问或做net映射

永久关闭防火墙命令

[root@localhost ~]# systemctl disable firewalld

关闭selinux

[root@localhost ~]# vim /etc/selinux/config

vim命令在最小安装时centos7系统没有自带，安装vim命令

yum install -y vim
