环境说明
| 主机名 | IP地址 | 应用 | 系统 |
|---|---|---|---|
| nginx | 192.168.183.135 | nginx负载均衡 | centos8 |
| RS1 | 192.168.183.136 | LNMP | centos8 |
| RS2 | 192.168.183.137 | apache | centos8 |
1、在RS2主机上安装apache服务
//修改主机名关闭防火墙和selinux
[root@localhost ~]# hostnamectl set-hostname RS2
[root@localhost ~]# bash
[root@RS2 ~]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@RS2 ~]# setenforce 0
[root@RS2 ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
//安装httpd
[root@RS2 ~]# dnf -y install httpd
//开启并设置开机自启httpd
[root@RS2 ~]# systemctl enable --now httpd
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.
[root@RS2 ~]# ss -antl
State Recv-Q Send-Q Local Address:Port Peer Address:Port Process

访问测试
2、在RS1主机上部署LNMP架构
//修改主机名关闭防火墙和selinux
[root@localhost ~]# hostnamectl set-hostname RS1
[root@localhost ~]# bash
[root@RS1 ~]# setenforce 0
[root@RS1 ~]# sed -ri 's/^(SELINUX=).*/\1disabled/g' /etc/selinux/config
[root@RS1 ~]# systemctl disable --now firewalld
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
