Nginx负载均衡
- 基于已有的web服务器，再克隆一个新的web服务器，取名为nginx2
[root@nginx2 ~]# vim /usr/local/nginx/conf/nginx.conf
# 修改监听地址为192.168.139.107
server_name 192.168.139.107;
[root@nginx2 ~]# /usr/local/nginx/sbin/nginx -s reload
- 新建负载均衡服务器
负载均衡配置
[root@lb ~]# vim /usr/local/nginx/conf/nginx.conf
http {
include mime.types;
default_type application/octet-stream;
upstream wordpress {
server 192.168.139.102;

location / {
proxy_pass http://wordpress;
proxy_set_header Host $host;
}
[root@lb ~]# /usr/local/nginx/sbin/nginx
Keepalived实现负载均衡服务器高可用
- 基于lb克隆lb2，用于实现高可用
- 安装keepalived
安装
yum install -y keepalived
备份配置文件
cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak
修改Master配置文件
[root@lb ~]# vim /etc/keepalived/keepalived.conf
29 virtual_ipaddress {
30 192.168.139.100
31 }
32 }
修改Backup配置文件
[root@lb2 ~]# vim /etc/keepalived/keepalived.conf
19 vrrp_instance VI_1 {
20 state BACKUP
21 interface ens33
22 virtual_router_id 51

[root@nfs ~]# cat /etc/exports
/upload 192.168.139.0/24(rw,no_root_squash)
[root@nfs ~]# chmod -R 766 /upload
- 安装并开启nfs
[root@nfs ~]# yum install -y nfs-utils.x86_64
[root@nfs ~]# systemctl start rpcbind
[root@nfs ~]# systemctl start nfs
[root@nfs ~]# ss -tnalp |grep 111
LISTEN 0 128 *:111 *:* users:(("rpcbind",pid=2560,fd=8))
LISTEN 0 128 [::]:111 [::]:* users:(("rpcbind",pid=2560,fd=11))
[root@nfs ~]# systemctl enable rpcbind
[root@nfs ~]# systemctl enable nfs
- web服务器（两个）创建共享目录并挂载
yum install rpcbind.x86_64 nfs-utils.x86_64 -y
