RHEL 8 搭建 Nginx Web 服务前请把 yum 源配好。
环境

Red Hat Enterprise Linux release 8.0
VMware Workstation Pro 14

搭建步骤
[root@localhost ~]# systemctl stop httpd #把 httpd 停掉，防止它影响 Nginx
[root@localhost ~]# yum install -y nginx
[root@localhost ~]# systemctl start nginx
[root@localhost ~]# iptables -F
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]# ifconfig

遇到 403 Forbidden 报错，原因是配置文件没配好，解决方法如下：

[root@localhost html]# grep -v "#" /etc/nginx/nginx.conf

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {

worker_connections 1024;

}

http {

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile            on;
tcp_nopush          on;
tcp_nodelay         on;
keepalive_timeout   65;
types_hash_max_size 2048;

include             /etc/nginx/mime.types;
default_type        application/octet-stream;

include /etc/nginx/conf.d/*.conf;

server {
    listen       80 default_server;
    listen       [::]:80 default_server;
    server_name  localhost;
    root         /usr/share/nginx/html;

    include /etc/nginx/default.d/*.conf;

    location / {
         index  index.html index.htm;
         autoindex on;
         autoindex_exact_size on;
         autoindex_localtime on;
         charset utf-8;
         } 
     }

}
参考以上配置进行修改

[root@localhost ~]# vim /etc/nginx/nginx.conf
[root@localhost ~]# systemctl restart nginx
