3. 配置 SSH 登录无密码验证
3.1 主库配置到 MHA manager 节点(备库节点)SSH登录无密码验证
vi /etc/hosts
192.168.222.157 mysqldb2
192.168.222.156 oradb
ssh-keygen -t rsa
ssh-coyp-id -i /root/.ssh/id_rsa.pub root@192.168.222.157
ssh-coyp-id -i /root/.ssh/id_rsa.pub root@192.168.222.156
ssh root@192.168.222.156
ssh root@oradb
ssh root@192.168.222.157
ssh root@mysqldb2
3.2 MHA manager 节点(备库节点)配置到主库配置 SSH登录无密码验证
vi /etc/hosts
192.168.222.157 mysqldb2
192.168.222.156 oradb
ssh-keygen -t rsa
ssh-coyp-id -i /root/.ssh/id_rsa.pub root@192.168.222.157
ssh-coyp-id -i /root/.ssh/id_rsa.pub root@192.168.222.156
ssh root@192.168.222.156
ssh root@oradb
ssh root@192.168.222.157
ssh root@mysqldb2
4. 搭建主从复制
4.1 修改主库my.cnf 配置服务器ID为10
vi /app/oracle/oradata2/mysql-5.6.27/my.cnf
[mysqld]
server_id = 10
4.1 修改备库my.cnf 配置
vi /usr/local/mysql/my.cnf
[mysqld]
server_id = 10
# slave config
log_bin=/usr/local/mysql/data/mysql-bin
relay_log=/usr/local/mysql/data/relay-bin
binlog_format=row
relay_log_purge=0
read_only=1
4.2 在主库上备份
mysqldump --master-data=2 --single-transaction -R -A > all.sql
其中 --master-data=2代表备份时刻记录 master的 Binlog 位置和 Position,--single-transaction 意思是获取一致性快照, -R 意思是备份相关的存储过程
,-A代表备份所有的 schema。
4.3 在主库上创建复制用户和 MHA监控用户
mysql> grant replication slave on *.* to 'repl'@'192.168.222.%' identified by '123456';
mysql> grant all on *.* to 'root'@'192.168.222.%' identified by '123456';
4.4 查看主库上备份时刻 Binlog 的名称和位置,MASTER_LOG和 MASTER_LOG_POS
head -n 30 all.sql|grep -i "CHANGE MASTER TO"
-- CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000068', MASTER_LOG_POS=325;
4.5 将备份复制到备库
scp all.sql root@192.168.222.157:/root/olm
4.6 在备库导入数据
mysql> source /root/olm/all.sql
mysql> flush privileges;
mysql>
change master to master_host='192.168.222.156',master_user='repl',master_password='123456',
master_port=3306,master_log_file='mysql-bin.000068',master_log_pos=325;
start slave;
--查看复制状态
show slave status \G
5. 配置MHA
5.1 创建 MHA 工作目录,并且创建相关配置文件
mkdir -p /etc/masterha
vi /etc/masterha/app1.cnf
[server default]
manager_log=/masterha/app1/app1.log
manager_workdir=/masterha/app1
master_binlog_dir=/app/oracle/oradata2/mysql-5.5.37/data
master_ip_failover_script=/usr/local/bin/master_ip_failover
master_ip_online_change_script=/usr/local/bin/master_ip_online_change
password=123456
ping_interval=1
remote_workdir=/tmp
repl_password=123456
repl_user=repl
secondary_check_script=/usr/local/bin/masterha_secondary_check -s mysqldb2 -s oradb --user=root --master_host=oradb --master_ip='192.168.222.156' --master_port=3306
shutdown_script=""
ssh_user=root
user=root
[server1]
hostname=192.168.222.156
port=3306
[server2]
candidate_master=1
check_repl_delay=0
hostname=192.168.222.157
port=3306
5.2 设置定期清理中继日志的脚本
crontab -e
0 4 * * * /usr/local/bin/purge_relay_logs --user=root --password=123456 --disable_replay_log_purge --port=3306 --workdir=/usr/local/mysql/data --disable_relay_log_purge >> /usr/loca/masterha/log/purge_relay_logs.log 2>&1
5.2 编辑 /etc/bashrc 文件,在文件末尾添加以下内容,避免MHA执行故障切换时无法找到 mysqlbinlog
PATH="$PATH:/usr/local/mysql/bin"
export PATH
5.3 检查 SSH 的配置
masterha_check_ssh --conf=/etc/masterha/app1.cnf
5.4 检查MYSQL复制
masterha_check_repl --conf=/etc/masterha/app1.cnf
5.5 启动 MHA Manger 监控
tail -f /masterha/app1/app1.log
--在另一个SSH 窗口启动 MHA Manger 监控。--remove_dead_master_conf 该参数代表当发生主从切换后,老的主库的IP将会从配置文件中移除。
--ignore_last_failover 在缺省情况下,如果MHA检测到连续发生宕机,而且两次宕机时间不足8小时的话,则不会进行 Failover,之所以这样限制
--是为了避免 ping-pong效应。该参数代表忽悠上次 MHA 触发切换产生的文件,默认情况下,MHA 发生切换后将会在 /masterha/paa1下产生 app1.
--failover.complete 文件,下次再次切换的时候如果发现目录存在该文件将不允许触发切换,除非在第一次切换后收到 rm -rf /masterha/paa1/app1. --failover.complete,出于方便考虑,我们每次启动MHA时会添加 --ignore_last_failover 参数。
nohup masterha_manager --conf=/etc/masterha/app1.cnf --remove_dead_master_conf --ignore_last_failover< /dev/null >/masterha/app1/manager.log 2>&1 &
--查看 MHA Manager 监控是否正常
masterha_check_status --conf=/etc/masterha/app1.cnf
app1 (pid:4758) is running(0:PING_OK), master:192.168.222.156
--在默认情况下,10秒内状态为10:INITIALIZING_MONITOR,当状态转变为0:PING_OK后表明已经开启了到 MASTER 端的监控。
关闭MHA的命令如下:
masterha_stop --conf=/etc/masterha/app1.cnf
6. 配置 VIP
6.1 在主库下载集群心跳软件 keepalived,并进行安装

7. 测试主库故障MHA自动把备库提升为主库并把虚拟IP漂移到新的主库(原来的备库)
7.1 在备库停止复制默认有二进制日志没传到备库
mysql> stop slave;
7.2 sysbench 生成测试数据,在主库上的 sbtest 库下创建 sbtest 表,共100万条数据
mysql> create database sbtest;
./sysbench --num-threads=4 --test=oltp --oltp-table-size=1000000 --oltp-read-only=off --init-rng=on --max-requests=0 \
--oltp-dist-type=uniform --max-time=1800 --mysql-user=root --db-driver=test --mysql-table-engine=innodb \
--oltp-test-mode=complex prepare
7.3 关闭主库 MHA会自动把备份库提升为新的主库,并把虚拟IP漂移到新的主库(原来的备库)
--关闭主库
mysqladmin -u root shutdown
--在MHA监控节点(备库)实时查看MHA日志
