ip地址规划
项目步骤
一.安装好8台全新的centos7.9的系统，关闭firewalld和selinux，配置每台主机的静态ip地址，设置每台主机对应的主机名。
1.关闭firewalld
2.关闭seLinux
3.配置每台主机静态ip地址（桥接模式）
4.设置每台主机对应的主机名
二.部署ansible服务器，配置SSH免密通道（单向），编写主机清单，使用ansible以二进制方式通过脚本一键安装MySQL。
1.安装epel源和ansible
2.建立免密通道，在ansible主机上生成密钥对
3.上传公钥到MySQL集群服务器的root用户家目录下
4.验证是否实现免密码密钥认证
5.编写主机清单
6.测试
7.MySQL官网下载mysql的二进制包，编写好一键安装脚本
三.在master服务器和ansible服务器之间建立双向的免密通道，方便同步数据。
四.部署4台MySQL服务器，一台master服务器，2台slave服务器，一台delay-backup延迟服务器，安装半同步相关的插件。
五.使用mysqldump在master服务器上导出基础数据，scp远程同步到ansible服务器，通过ansible服务器下发到salve服务器。
六.在slave服务器上使用mysql导入master服务器的基础数据。
1.slave服务器上直接导入
2.使用ansible（shell模块）导入基础数据
七.MySQL集群开启GTID功能，启动主从复制服务，配置好延迟备份服务器，从slave-1上拿二进制日志。
1.安装插件
master服务器上操作
salve服务器上操作
使用ansible的playbook来下载插件和检查插件是否安装
2.修改master和salve配置文件
在master上操作
3.在slave-1上操作（即是slave也是master）
4.在slave-2上操作
5.配置好延迟备份服务器，从slave-1上拿二进制日志。
6.测试
八.部署mysql的failover插件（MHA），实现自动的故障切换，如果master宕机，能自动提升其中一台slave为新的master，其他slave到新的master上获得二进制日志。
0.前提条件（准备好rpm包）
MySQL集群都安装mha4mysql-node
1.下载该软件需要的依赖包
2.通过ansible使用rpm安装rpm包
3.管理节点安装mha4mysql-manager，延迟服务器同时是管理节点
4.建立免密通道
5.创建监控用户（一台master和2台slave都要创建，delay-backup服务器不用）
配置MHA
1.创建工作目录
2.在/usr/local/bin目录下创建脚本master_ip_failover（故障切换脚本，切换master的VIP地址）
3.给脚本可执行权限
4.在/etc/masterha下创建配置文件app1.cnf
5.检查管理节点到所有Node节点的ssh连接状态
6.检查复制环境。
7.检查管理节点的状态
8.开启管理节点监控
9.关闭master服务器的mysqld
10.管理节点查看配置文件，会发现[server1]模块和user=root被删除了。
九.在master上创建一个计划任务每天2:30进行数据库的备份，编写备份脚本，备份文件包含当天的日期，使用rsync+sersync远程同步到ansible服务器。
编写脚本
部署rsync+sersync
1.ansible服务器操作
2.master服务器操作
3.实现自动同步
4.查看rsync的帮助文档
十.部署两台安装了mysqlrouter中间件软件的服务器，实现读写分离和高可用功能。
十一.在两台mysqlrouter服务器上安装keepalived软件，配置2个vrrp实例，互为主备，来实现双vip的高可用功能。
十二.使用dns实现负载均衡，在云平台（阿里云、腾迅云等）购买域名，然后在域名里添加两条A记录，同一个域名对应着2个vip。
十三.使用压力测试软件（sysbench或tcpp）对整个mysql集群进行压力测试。
使用sysbench进行测试
mysql性能测试工具——tpcc-mysql

项目步骤
一.安装好8台全新的centos7.9的系统，关闭firewalld和selinux，配置每台主机的静态ip地址，设置每台主机对应的主机名。
1.关闭firewalld
# 立即关闭firewalld
systemctl stop firewalld
# 设置firewalld开启不启动
systemctl disable firewalld
# 查看firewalld的状态
systemctl status firewalld
2.关闭seLinux
# 临时关闭seLinux
setenforce 0

注意：如果 Slave_IO_Running、Slave_SQL_Running的状态是 NO
需要检查
1.检查配置文件是否打错
2.修改配置文件后是否重启MySQL服务
3.可能slave上的GTID编号比master上的还大
如果是第三种情况，清空二进制日志。
# master 上操作
# 清空二进制日志
reset master;

八.部署mysql的failover插件（MHA），实现自动的故障切换，如果master宕机，能自动提升其中一台slave为新的master，其他slave到新的master上获得二进制日志。
0.前提条件（准备好rpm包）
mha4mysql-node-0.56-0.el6.noarch.rpm
mha4mysql-manager-0.56-0.el6.noarch.rpm
MySQL集群都安装mha4mysql-node
1.下载该软件需要的依赖包
yum install epel-release -y
yum -y install perl-DBD-MySQL perl-Config-Tiny perl-Log-Dispatch perl-Parallel-ForkManager2.通过ansible使用rpm安装rpm包
ansible db -m shell -a 'rpm -ivh /root/mha4mysql-node-0.56-0.el6.noarch.rpm'3.管理节点安装mha4mysql-manager，延迟服务器同时是管理节点

管理节点delay-backup要能免密登录主从复制的所有服务器，而不需要反向免密登录。主从复制的所有服务器之间要能免密登录。
ssh-keygen -t rsa
ssh-copy-id -i id_rsa.pub [email protected].%5.创建监控用户（一台master和2台slave都要创建，delay-backup服务器不用）
grant all privileges on *.* to 'monitor'@'192.168.0.%' identified by '123456';
# 刷新权限
flush privileges;配置MHA
1.创建工作目录
mkdir /etc/masterha
mkdir -p /var/log/masterha/app12.在/usr/local/bin目录下创建脚本master_ip_failover（故障切换脚本，切换master的VIP地址）
cd /usr/local/bin
[root@delay-backup bin]# vim master_ip_failover
#!/usr/bin/env perl
use strict;
use warnings FATAL =>'all';
use Getopt::Long;
my (
$command, $ssh_user, $orig_master_host, $orig_master_ip,
$orig_master_port, $new_master_host, $new_master_ip, $new_master_port

my $key = "1";
my $ssh_start_vip = "/sbin/ip a add $vip dev ens33:$key"; #这两行需要修改，一行是临时添加IP，一行是临时删除IP
my $ssh_stop_vip = "/sbin/ip a del $vip dev ens33:$key"; #注意能够使用的命令是ip还是ifconfig，以及网卡名称
my $exit_code = 0;

'new_master_host=s' => \$new_master_host,
'new_master_ip=s' => \$new_master_ip,
'new_master_port=i' => \$new_master_port,
);
exit &main();

};
if ($@) {

}3.给脚本可执行权限
chmod 777 /usr/local/bin/master_ip_failover4.在/etc/masterha下创建配置文件app1.cnf
[root@delay-backup bin]# vim /etc/masterha/app1.cnf

rsync version 3.1.2 protocol version 31
Copyright (C) 1996-2015 by Andrew Tridgell, Wayne Davison, and others.
Web site: http://rsync.samba.org/
Capabilities:
64-bit files, 64-bit inums, 64-bit timestamps, 64-bit long ints,
socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
append, ACLs, xattrs, iconv, symtimes, prealloc

General Public Licence for details.
rsync is a file transfer program capable of efficient remote update
via a fast differencing algorithm.
Usage: rsync [OPTION]... SRC [SRC]... DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
or rsync [OPTION]... [USER@]HOST:SRC [DEST]
or rsync [OPTION]... [USER@]HOST::SRC [DEST]
or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.
