篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ansible_playbook 一键搭建集群架构相关的知识，希望对你有一定的参考价值。
目录
服务器主机名和 IP 规划参考模板
| 主机名 | eth0 网卡 | eth1 网卡 | 服务简介 |
|---|---|---|---|
| lb01 | 10.0.0.5/24 | 172.16.1.5/24 | 负载服务 |
| lb02 | 10.0.0.6/24 | 172.16.1.6/24 | 负载服务 |
| web01 | 10.0.0.7/24 | 172.16.1.7/24 | phpwww 服务 |
| web02 | 10.0.0.8/24 | 172.16.1.8/24 | php www 服务 |
| tweb01 | 10.0.0.9/24 | 172.16.1.9/24 | tomcat www 服务 |
| db01 | 10.0.0.51/24 | 172.16.1.51/24 | 数据库服务 |
| nfs01 | 10.0.0.31/24 | 172.16.1.31/24 | 存储服务 |
| backup | 10.0.0.41/24 | 172.16.1.41/24 | 备份服务 |
| m01 | 10.0.0.61/24 | 172.16.1.61/24 | 管理服务 |
基础优化
修改ip地址
sed -i ‘s#222#61#g‘ /etc/sysconfig/network-scripts/ifcfg-eth[01]
永久修改主机名
[[email protected] ~]# hostnamectl set-hostname oldboyedu-cc7
[[email protected] data]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.1.5 lb01
172.16.1.6 lo02
172.16.1.7 web01
172.16.1.8 web02
172.16.1.9 sweb
172.16.1.31 nfs
172.16.1.41 backup
172.16.1.51 db
#批量推送其他主机
[[email protected] data]# scp -rp /etc/hosts [email protected]:/etc/
//2.关闭firewalld防火墙
systemctl disable firewalld
systemctl stop firewalld
systemctl status firewalld
//3.关闭selinux
# 方式一
sed -ri ‘s#(^SELINUX=).*#1disabled#g‘ /etc/selinux/config
# 方式二
sed -i ‘/^SELINUX=/c SELINUX=disabled‘ /etc/selinux/config
# 方式三
vim /etc/selinux/config
# 临时生效
setenforce 0
//4.优化ulimit
echo ‘* - nofile 65535‘ >> /etc/security/limits.conf
//5 重启快照SSH、Ansible,批量管理服务项目
1.创建密钥对
[[email protected] ~]# ssh-keygen -t rsa -C xuliangwei.com #一路回车即可
[[email protected] ~]# ls ~/.ssh/
id_rsa(钥匙) id_rsa.pub(锁头)
2#发送密钥给需要登录的用户
[[email protected] ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
# 测试
#远程登录对端主机方式
[[email protected] ~]# ssh [email protected]
# 不登陆主机执行命令
[[email protected] ~]# ssh [email protected] "hostname -i"
.ansible借助公钥批量管理
#利用非交换式工具实现批量分发公钥与批量管理服务器
[[email protected] ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
[[email protected] ~]# yum install ansible -y
//检查ansible版本
[[email protected] ~]# ansible --version
ansible 2.6.1
配置ansible 主机清单
[[email protected] ~]# vim /etc/ansible/hosts
[lb]
172.16.1.5
172.16.1.6
[web]
172.16.1.7
172.16.1.8
[sweb]
172.16.1.9
[nfs]
172.16.1.31
[backup]
172.16.1.41
[db]
172.16.1.51
测试
# ansible是通过ssh端口探测通信
[[email protected] ~]# ansible all -m ping
#批量执行命令
[[email protected] ~]# ansible all -m command -a "df -h"
[[email protected] ~]# ansible all -m command -a "hostname"

善后操作
#4.由于mysql5.7默认配置了默认密码, 需要过滤temporary password关键字查看对应登陆数据库密码
[[email protected] ~]# grep ‘temporary password‘ /var/log/mysqld.log
#5.登陆mysql数据库[password中填写上一步过滤的密码]
[[email protected] ~]# mysql -uroot -p$(awk ‘/temporary password/{print $NF}‘ /var/log/mysqld.log)
#6.重新修改数据库密码
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘Ckh123.com‘;
# 服务器mysql允许远程用户连接 (授权法)
grant all privileges on *.* to ‘all‘@‘%‘ identified by ‘Ckh123.com‘;
flush privileges;
1.老服务器操作
#1.指定导出对应的数据库文件。
[[email protected] ~]# mysqldump -uroot -p‘Ckh123.com‘ --all-databases --single-transaction > `date +%F%H`-mysql-all.sql
#2.传输备份数据库文件至新服务器
[[email protected] zh]# scp 2018-10-0613-mysql-all.sql [email protected]:/tmp
2.新服务器操作
#1.导入数据库
[[email protected] ~]# cd /tmp && mysql -uroot -p‘Ckh123.com‘ < 2018-10-0613-mysql-all.sql
# 手动启动tomcat8
/usr/bin/sh /server/tomcat8_1/bin/startup.sh扩展 zip命令使用
# 当前目录下 所有文件 压缩包
[[email protected] conf.d]# zip conf.zip ./*
# -r 递归所有目录
[[email protected] conf.d]# zip -r conf.zip ./*
2.unzip
unzip -o -d /home/sunny myfile.zip
把myfile.zip文件解压到 /home/sunny/
-o:不提示的情况下覆盖文件；
-d:-d /home/sunny 指明将文件解压缩到/home/sunny目录下；
3.其他
zip -d myfile.zip smart.txt
删除压缩文件中smart.txt文件
zip -m myfile.zip ./rpm_info.txt
向压缩文件中myfile.zip中添加rpm_info.txt文件源码下载地址
