centos7联网安装nginx

1. 安装先决条件

sudo yum install yum-utils

2. 创建/etc/yum.repos.d/nginx.repo文件来设置yum存储库(先查看是否有再创建)

cd  /etc/yum.repos.d
touch nginx.repo

3. 将下列内容复制到nginx.repo中

[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
module_hotfixes=true

[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
module_hotfixes=true

4. 在线安装nginx

sudo yum install nginx

5. 启动，进入在/usr/sbin目录

cd /usr/sbin
./nginx

6. 验证是否启动

ps -ef | grep nginx

7. 验证主机访问服务器的nginx
   
8. 注意事项
   访问失败的情况下查看服务器防火墙是否关闭,端口是否开放

#查看防火墙状态
systemctl status firewalld
#关闭防火墙
systemctl stop firewalld
#开机禁用防火墙
systemctl disable firewalld
