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~",

    "changed": true,

    "checksum": "221c515383928f333f15de0e7b68a49de47bf1d8",

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
