ansible_playbook  一键搭建集群架构

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

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
[root@oldboy-c7 ~]# hostnamectl set-hostname oldboyedu-cc7
[root@web01 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
[root@web01 data]# scp -rp /etc/hosts root@172.16.1.31:/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
[root@m01 ~]# ssh-keygen -t rsa -C xuliangwei.com #一路回车即可
[root@m01 ~]# ls ~/.ssh/
id_rsa(钥匙) id_rsa.pub(锁头) 2#发送密钥给需要登录的用户
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.31 # 测试
#远程登录对端主机方式
[root@m01 ~]# ssh root@172.16.1.41
# 不登陆主机执行命令
[root@m01 ~]# ssh root@172.16.1.41 "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
[root@m01 ~]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.16.1.41 [root@m01 ~]# yum install ansible -y //检查ansible版本
[root@m01 ~]# ansible --version
ansible 2.6.1 配置ansible 主机清单
[root@m01 ~]# 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
[root@m01 ~]# ansible all -m ping
#批量执行命令
[root@m01 ~]# ansible all -m command -a "df -h"
[root@m01 ~]# 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
[root@nginx ~]# 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]
[root@web02 ~]# 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。
[root@web02 ~]# 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
[root@web02 zh]# scp 2018-10-0613-mysql-all.sql root@10.0.0.51:/tmp 2.新服务器操作
#1.导入数据库
[root@db01 ~]# 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
[root@web01 conf.d]# zip conf.zip ./*
# -r 递归所有目录
[root@web01 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
