环境:在分布式基础上搭建nfs
nginx1:192.168.8.10
mysql:192.168.8.20
php: 192.168.8.30
nfs: 192.168.8.40
nginx2: 192.168.8.50
nginx_lb: 192.168.8.60
1.搭建nfs共享服务器,把网站静态元素通过挂载方式放在nfs上
(1)开启一台centos7,安装nfs-utils、rpcbind:
yum -y install nfs-utils rpcbind
(2)创建挂载点
mkdir -p /nfs/blog
(3)发布共享目录
vim /etc/exports
添加:
/nfs/blog 192.168.8.0/24(rw,sync,no_root_squash)
保存退出
(4)重启nfs服务
systemctl restart rpcbind systemctl restart nfs
(5)在nginx服务器上查看nfs共享目录
showmount -e 192.168.8.40
(6)把wordpress的内容目录挂载到nfs
cd /wordpress cp -rp wp-content/ wp-contentbak mount -t nfs 192.168.8.40:/nfs/blog wp-content cp -rp wp-contentbak/* wp-content/
(7)设置永久挂载
vim /etc/fstab
添加:
192.168.8.40:/nfs/log /wordpress/wp-content nfs defaults 0 0
保存退出
2.搭建第二台web服务器
(1)安装nginx
yum -y epel-release yum -y install nginx
(2)把web1(192.168.8.10)上的nginx的配置复制到web2(192.168.8.50)
scp -rp /etc/nginx/* root@192.168.8.50:/etc/nginx
(3)把web1上网页源码复制到web2
scp -rp /wordpress root@192.168.8.50:/
(4)启动服务
systemctl start nginx
3.搭建nginx负载均衡(192.168.8.60)
(1)安装nginx
yum -y install epel-release yum -y install nginx
(2)配置负载均衡
vim /etc/nginx/conf.d/lb1.conf
添加:
upstream webcluster { server 192.168.8.10:80; server 192.168.8.50:80; } server { listen 80; server_name blog.benet.com; location / { proxy_pass http://webcluster; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } }
保存退出
systemctl restart nginx
4.nginx1和nginx2,动态查看nginx访问日志
tail -f /var/log/nginx/access.log
5.客户端修改/etc/hosts,指向lb服务器,访问网站
vim /etc/hosts 192.168.8.60 blog.benet.com
