使用windos电脑模拟搭建web集群(一)
资源规划
1.环境准备
centos7.2 虚拟机 13个 可以先配置一台，做好基础优化，然后克隆13台分布在 windos宿主机上
两台windos笔记 都是8g的内存 一台有点内存吃紧。 没有物理服务器玩，屌丝的玩法，有硬件资源的老兄，只能羡慕你了 。
vmare 虚拟 13台虚拟机
eth0 用的是nat模式 eth1用是桥接模式
2.在监控主机安装ansible
直接yum安装
yum install -y ansible
如果不想配置密钥对使用ansible
更改 /etc/ansible/ansible.cfg 配置
host_key_checking = False //打开这个注释
3.根据资源分布表配置ansible的 主机清单
[root@mage-monitor- ~]# tail - /etc/ansible/hosts
192.168.5.103 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.110 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.111 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.130 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.131 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.132 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.150 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.151 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.152 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.153 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.161 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.162 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.163 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.200 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
192.168.5.201 ansible_ssh_port= ansible_ssh_user=root ansible_ssh_pass=
测试一下配置
[root@mage-monitor- ~]# ansible all -m ping
192.168.5.130 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.102 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.110 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.101 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.111 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.131 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.161 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.150 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.153 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.151 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.162 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.201 | SUCCESS => {
"changed": false,
"ping": "pong"
}
192.168.5.200 | SUCCESS => {
"changed": false,
"ping": "pong"
}
4.配置DNS （所有主机）
先在monitor主机上配一份 然后用ansible的copy模块批量分发
直接复制excel 也管用
[root@mage-monitor- ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
:: localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.5.101 LB-nginx- lb01.woniu.com
192.168.5.102 LB-nginx- lb02.woniu.com
192.168.5.110 WEB-LNMJ- web01.woniu.com
192.168.5.111 WEB-LNMJ- web02.woniu.com
192.168.5.130 STORE-NFS- nfs.woniu.com
192.168.5.131 STORE-Rsync- rsync.woniu.com
192.168.5.150 MySQL-master- dbmaster01.woniu.com
192.168.5.151 MySQL-master- dbmaster02.woniu.com
192.168.5.153 MySQL-slave- dbslave01.woniu.com
192.168.5.161 Cache-Mc- cache01.woniu.com
192.168.5.162 Cache-Mc- cache02.woniu.com
192.168.5.200 MAGE-monitor- monitor.woniu.com
192.168.5.201 MAGE-jump- jump.woniu.com
随机测试一个是否真的管用
结论：管用
4.使用ansible copy模块分发文件
[root@mage-monitor- ~]# ansible all -m copy -a "src=/etc/hosts dest=/etc/ backup=yes"
192.168.5.111 | SUCCESS => {
"backup_file": "/etc/hosts.4654.2018-07-04@05:43:06~",

其他所有主机是黄色的 success 而 200这台主机是绿色的，因为200这台的hosts文件就是我分发的这个
内容相同不覆盖，其他主机的hosts内容不一致都被覆盖了 所以显示黄色
我还加了一个参数backup=yes
检验一下，任选一台主机 hosts文件已被更改
并且还备份了 一个原来的
基础环境 就搞完了，下面就是在各台主机上 安装软件配置软件
