1.3Rs1 安装nginx 添加虚拟IP arp抑制
#关闭防火墙和slinux
[root@rs1 ~]# systemctl stop firewalld.service
[root@rs1 ~]# setenforce 0
[root@rs1 ~]# yum -y install nginx
[root@rs1 ~]# echo "rs1" > /usr/share/nginx/html/index.html
[root@rs1 ~]# systemctl enable --now nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@rs1 ~]# curl 127.0.0.1 rs1
[root@rs1 ~]# ip addr add 192.168.26.222/32 dev ens33 label ens33:1
[root@rs1 ~]# vim /etc/sysctl.conf #在末尾插入
[root@rs1 ~]# sysctl -p
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2
1.4RS2同上
[root@rs2 ~]# systemctl stop firewalld.service
[root@rs2 ~]# setenforce 0
[root@rs2 ~]# yum -y install nginx
[root@rs2 ~]# echo "rs2" > /usr/share/nginx/html/index.html
[root@rs2 ~]# systemctl enable --now nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@rs2 ~]# ip addr add 192.168.26.222/32 dev lo label lo:1
[root@rs2 ~]# curl 127.0.0.1
rs2
[root@rs2 ~]# vim /etc/sysctl.conf
[root@rs2 ~]# sysctl -p
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2
1.5测试
二.实现后端服务器上运行wordpress博客站点
2.1Rs1 rs2继续配置 都配置PHP环境（编译安装）
[root@rs1 ~]# yum -y remove php-fpm php-mysqlnd php-json #（删除自带yum安装的）
