TiDB Binlog部署

先造点数据

yum install sysbench -ymysql -uroot -p -h10.152.x.10 -P4000 -e"create database sysbench"sysbench /usr/share/sysbench/oltp_read_write.lua  --mysql-user=root --mysql-password=supersecret --mysql-port=4000 \
--mysql-host=10.152.x.10 \
--mysql-db=sysbench  --tables=10 --table-size=5000  --threads=4 \
--events=5000 --report-interval=5 --db-driver=mysql prepare

部署Pump

1.修改 tidb-ansible/inventory.ini 文件

设置 enable_binlog = True，表示 TiDB 集群开启 binlog

## binlog trigger
enable_binlog = True

2.为 pump_servers 主机组添加部署机器 IP

[pump_servers
pump1 ansible_host=10.152.x.10
pump2 ansible_host=10.152.x.11
pump3 ansible_host=10.152.x.12

如果想要为pump专门指定目录, 可以使用deploy_dir

pump1 ansible_host=10.152.x.10 deploy_dir=/data1/pump
pump2 ansible_host=10.152.x.11 deploy_dir=/data2/pump
pump3 ansible_host=10.152.x.12 deploy_dir=/data3/pump

默认 Pump 保留 7 天数据，如需修改可修改 tidb-ansible/conf/pump.yml（TiDB 3.0.2 及之前版本中为 tidb-ansible/conf/pump-cluster.yml）文件中 gc 变量值，并取消注释。

global:# an integer value to control the expiry date of the binlog data, which indicates for how long (in days) the binlog data would be stored# must be bigger than 0# gc: 7

3.部署 pump_servers 和 node_exporters

ansible-playbook deploy.yml --tags=pump -l pump1,pump2,pump3

如果没有为pump指定别名则为

ansible-playbook deploy.yml --tags=pump -l 10.152.x.10,10.152.x.11,10.152.x.12

以上命令中，逗号后不要加空格，否则会报错

4.启动 pump_servers

ansible-playbook start.yml --tags=pump

查看一下

# ps -ef| grep pump
tidb     26199     1  0 21:05 ?        00:00:00 bin/pump --addr=0.0.0.0:8250 --advertise-addr=pump1:8250 --pd-urls=http://10.152.x.10:2379,http://10.152.x.11:2379,http://10.152.x.12:2379 --data-dir=/DATA1/home/tidb/deploy/data.pump --log-file=/DATA1/home/tidb/deploy/log/pump.log --config=conf/pump.toml

5.更新并重启 tidb_servers

为了让enable_binlog = True生效

ansible-playbook rolling_update.yml --tags=tidb

6.更新监控信息

ansible-playbook rolling_update_monitor.yml --tags=prometheus

7.查看 Pump 服务状态

使用 binlogctl 查看 Pump 服务状态，pd-urls 参数请替换为集群 PD 地址，结果 State 为 online 表示 Pump 启动成功

$resources/bin/binlogctl -pd-urls=http://10.152.x.10:2379 -cmd pumps
[2019/12/01 21:11:47.655 +08:00] [INFO] [nodes.go:49] ["query node"] [type=pump] [node="{NodeID: knode10-152-x-12:8250, Addr: pump3:8250, State: online, MaxCommitTS: 412930776489787394, UpdateTime: 2019-12-01 21:11:45 +0800 CST}"]

[2019/12/01 21:11:47.655 +08:00] [INFO] [nodes.go:49] ["query node"] [type=pump] [node="{NodeID: knode10-152-x-11:8250, Addr: pump2:8250, State: online, MaxCommitTS: 412930776489787393, UpdateTime: 2019-12-01 21:11:45 +0800 CST}"]

或者登陆TiDB使用show pump status查看状态

root@10.152.x.10 21:10:32 [(none)]> show pump status;
+-----------------------+------------+--------+--------------------+---------------------+

部署Drainer

部署Drainer将MySQL作为TiDB从库

1.下载tidb-enterprise-tools安装包

wget http://download.pingcap.org/tidb-enterprise-tools-latest-linux-amd64.tar.gz
tar -zxvf tidb-enterprise-tools-latest-linux-amd64

2.使用TiDB Mydumper备份TiDB数据

$sudo ./tidb-enterprise-tools-latest-linux-amd64/bin/mydumper --ask-password -h 10.152.x.10 -P 4000 -u root --threads=4 --chunk-filesize=64 --skip-tz-utc --regex '^(?!(mysql\.|information_schema\.|performance_schema\.))'  -o /mfw_rundata/dump/ --verbose=3

3.修改 tidb-ansible/inventory.ini 文件

为 drainer_servers 主机组添加部署机器 IP，initial_commit_ts 请设置为获取的 initial_commit_ts，仅用于 Drainer 第一次启动

[drainer_servers]
drainer_mysql ansible_host=10.152.x.12 initial_commit_ts="412931068452667405"

修改配置文件

[tidb@knode10-152-x-133 21:33:21 ~/tidb-ansible]
$cp conf/drainer.toml conf/drainer_mysql_drainer.tomlvim conf/drainer_mysql_drainer.tomldb-type = "mysql"[syncer.to]
host = "10.132.2.143"
user = "drainer"
password = "drainer_supersecret"
port = 3308

4.部署Drainer
