一、所有节点的操作
1：配置Percona存储 库
cd /opt;wget https://repo.percona.com/yum/percona-release-latest.noarch.rpm --no-check-certificate
rpm -ivh percona-release-latest.noarch.rpm
[root@beiyong opt]# yum list | grep percona-xtrabackup
percona-xtrabackup.x86_64 2.3.10-1.el7 percona-release-x86_64
percona-xtrabackup-22.x86_64 2.2.13-1.el7 percona-release-x86_64
percona-xtrabackup-22-debuginfo.x86_64 2.2.13-1.el7 percona-release-x86_64
percona-xtrabackup-24.x86_64 2.4.13-1.el7 percona-release-x86_64
percona-xtrabackup-24-debuginfo.x86_64 2.4.13-1.el7 percona-release-x86_64
percona-xtrabackup-debuginfo.x86_64 2.3.10-1.el7 percona-release-x86_64
percona-xtrabackup-test.x86_64 2.3.10-1.el7 percona-release-x86_64
percona-xtrabackup-test-22.x86_64 2.2.13-1.el7 percona-release-x86_64
percona-xtrabackup-test-24.x86_64 2.4.13-1.el7 percona-release-x86_64
2：安装Percona XtraDB Cluster软件包：
yum clean all;yum -y install epel-release
yum install Percona-XtraDB-Cluster-57 -y （如有报错某个软件包没有下载，请复制软件包名称继续yum下载）
3:修改配置文件（三台节点都修改好）

slow_query_log = ON
slow_query_log_file = /home/mysql/log/slow.log

sort_buffer_size = 4M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]

!includedir /etc/my.cnf.d
:wq
4:创建以上配置文件中需要的目录，并更改权限
mkdir -p /home/mysql/{data,log,binlog};chown mysql.mysql -R /home/mysql/
5：启动节点1--注意！！！这个只是第一个节点启动的命令
systemctl start [email protected]
（启动时多开一个窗口，观察有没有错误日志 tailf /home/mysql/log/error.log）
获取初始密码： &7(,Sl=1sa&2
grep 'temporary password' /home/mysql/log/error.log
2019-04-17T13:47:48.758384Z 1 [Note] A temporary password is generated for root@localhost: &7(,Sl=1sa&2
使用初始密码进入数据库，设置root密码：本地登录授权(这边授权以后，其他的节点启动后，数据自动同步过去了)
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';flush privileges;
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.01 sec)
为了使用XtraBackup执行成功的状态快照传输，需要使用适当的权限设置新用户，(这边授权以后，其他的节点启动后，数据自动同步过去了)
mysql> CREATE USER 'sstuser'@'localhost' IDENTIFIED BY 'sstuserpwd';
mysql> GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON *.* TO 'sstuser'@'localhost';FLUSH PRIVILEGES;
6：检查集群状态
mysql> show status like 'wsrep%';

6：启动其他的节点：（启动时多开一个窗口，观察有没有错误日志 tailf /home/mysql/log/error.log）
systemctl start mysqld
查看是否成功加入集群中
mysql> show status like 'wsrep%';
wsrep_cluster_size 2 --第二个节点加入成功
wsrep_cluster_size 3 --第三个节点加入成功
7：数据同步测试
在某个节点上创建库和插入数据，看看其他节点上数据同步过来没有
[root@PXC-3 ~]# cat /home/mysql/data/grastate.dat

解决：
cd /home/mysql/data
rm -rf ibdata1 ib_logfile0 ib_logfile1
再次启动：
systemctl start [email protected]
（启动时多开一个窗口，观察有没有错误日志 tailf /home/mysql/log/error.log）
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 故障模拟 单节点或者双节点故障 ~~~~~~~~~~~~~~~~
一、只停掉节点2：节点1为主
[root@PXC-2 ~]#systemctl stop mysqld
再在节点1和2上查看集群数量和状态：
mysql> show status like 'wsrep%';
…………
wsrep_cluster_size | 2 --剩下两个节点
wsrep_cluster_status | Primary --集群状态正常
恢复：
1：直接启动systemctl start mysqld:
2：如果其他节点的集群状态不属于：wsrep_cluster_status ！= Primary --集群状态不正常
恢复：删除数据目录里面的全部内容
[root@PXC-2 ~]# ls /home/mysql/data/
auto.cnf ca.pem client-key.pem grastate.dat ibdata1 ib_logfile1 performance_schema public_key.pem server-key.pem xtrabackup_binlog_pos_innodb xtrabackup_info
ca-key.pem client-cert.pem galera.cache ib_buffer_pool ib_logfile0 mysql private_key.pem server-cert.pem sys xtrabackup_galera_info xtrabackup_master_key_id
[root@PXC-2 ~]# rm -rf /home/mysql/data/*
再启动：systemctl start mysqld
二、 只停掉节点2和3：节点1为主
再在节点1上查看集群数量和状态：
mysql> show status like 'wsrep%';
…………
wsrep_cluster_size | 1 --剩下1个节点
wsrep_cluster_status | Primary --集群状态正常
恢复：直接一个节点一个节点的恢复（数据量大的话，怕数据库压力太大）
systemctl start mysqld
如果集群状态不是正常的值： ！=Primary
恢复：删除数据目录里面的全部内容
[root@PXC-2 ~]# ls /home/mysql/data/
auto.cnf ca.pem client-key.pem grastate.dat ibdata1 ib_logfile1 performance_schema public_key.pem server-key.pem xtrabackup_binlog_pos_innodb xtrabackup_info
ca-key.pem client-cert.pem galera.cache ib_buffer_pool ib_logfile0 mysql private_key.pem server-cert.pem sys xtrabackup_galera_info xtrabackup_master_key_id
[root@PXC-2 ~]# rm -rf /home/mysql/data/*
再启动：systemctl start mysqld
三、只停掉节点1，节点1为主
systemctl stop mysqld --这个命令没用的话，也没事，只是等下作为节点启动时先要systemctl stop mysqld再systemctl start mysqld
systemctl stop [email protected]
再在节点2和3上查看集群数量和状态：
mysql> show status like 'wsrep%';
…………
wsrep_cluster_size | 2 --剩下2个节点
wsrep_cluster_status | Primary --集群状态正常
恢复：不能直接这样启动--会报错，但是不影响现有的两个节点集群
[root@PXC-1 ~]# systemctl start [email protected]
Job for [email protected] failed because the control process exited with error code. See "systemctl status [email protected]" and "journalctl -xe" for details.
正确恢复：
[root@PXC-1 ~]# systemctl start mysqld
再在节点2和3上查看集群数量和状态：
mysql> show status like 'wsrep%';
…………
wsrep_cluster_size | 3 --剩下3个节点
wsrep_cluster_status | Primary --集群状态正常
四、如果在主节点1上不小心执行了：systemctl stop mysqld --这个不影响集群
如果在主节点1上不小心执行了：systemctl start mysqld --这个不影响集群
只是会报错一下：
[root@PXC-1 etc]# systemctl start mysqld
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
五、以上模拟的故障这个值全部节点不变：
[root@PXC-3 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state
version: 2.1
uuid: 67d01e5b-6117-11e9-a1db-3743261561ca
seqno: 5 --值从 -1 变为 5（每停一个节点，某个节点的值变为5）
safe_to_bootstrap: 0 --值不变
六、如果还是节点1作为主启动会直接报错：
[root@PXC-1 ~]# systemctl start [email protected]
Job for [email protected] failed because the control process exited with error code. See "systemctl status [email protected]" and "journalctl -xe" for details.
总结：
[root@PXC-2 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state
version: 2.1
uuid: 67d01e5b-6117-11e9-a1db-3743261561ca
seqno: -1 --这个值为 -1时，节点没有挂逼，为 5 时节点挂逼了
safe_to_bootstrap: 0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 故障模拟 全部节点故障 ~~~~~~~~~~~~~~~~
1：停掉主节点3,再停掉2，再停掉1 --这次节点3是主，这个停的时候用两个命令
[root@PXC-3 ~]# systemctl stop [email protected]
[root@PXC-3 ~]# systemctl stop mysqld --这个命令没用的话，也没事，只是等下作为节点启动时先要systemctl stop mysqld再systemctl start mysqld
再在节点1和2上：查看集群状态：wsrep_cluster_size 2，wsrep_cluster_status Primary
[root@PXC-2 ~]# systemctl stop mysqld
[root@PXC-1 ~]# systemctl stop mysqld
[root@PXC-3 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state
version: 2.1
uuid: 67d01e5b-6117-11e9-a1db-3743261561ca

[root@PXC-2 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state

uuid: 67d01e5b-6117-11e9-a1db-3743261561ca

seqno: 5 --没有变化
safe_to_bootstrap: 1 --最后一个停的值变为1了
恢复：按照正常顺序恢复：
[root@PXC-1 ~]# systemctl start [email protected] --没有报错，集群状态和数量也正常
[root@PXC-2 ~]# systemctl start mysqld --没有报错，集群状态和数量也正常
[root@PXC-3 ~]# systemctl start mysqld --没有报错，集群状态和数量也正常
[root@PXC-1 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state

seqno: -1 --恢复到故障之前
safe_to_bootstrap: 0 --恢复到故障之前
总结：节点全部挂了时，选择某个节点作为主节点启动：
启动之前查看：
[root@PXC-1 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state
version: 2.1
uuid: 67d01e5b-6117-11e9-a1db-3743261561ca
seqno: 5 --5代表节点是挂逼的，-1 时代表节点没有挂逼
safe_to_bootstrap: 1 --最后一个停的值为1，这个作为主节点启动
集群全部正常时：
[root@PXC-2 ~]# cat /home/mysql/data/grastate.dat
# GALERA saved state
version: 2.1
uuid: 67d01e5b-6117-11e9-a1db-3743261561ca
seqno: -1 --每个节点的值都一样
