Mysql + canal + zookeeper环境搭建

Mysql + canal + zookeeper环境搭建

一、mysql集群搭建

1. mysql基本环境

操作系统： Linux version 2.6.32-431.el6.x86_64

数据库：MySQL Community Server 5.7.20

主节点IP：10.60.81.157

主节点IP：10.60.81.158

从节点IP：10.60.81.159

2. 安装mysql

2.1．官网下载MySQL

mysql-5.7.20-1.el6.x86_64.rpm-bundle.tar

2.2. 三个节点都安装：

2.2.1．三个节点查看是否安装mysql

rpm -qa | grep mysql

rpm -e --nodeps mysql-libs-5.1.66-2.el6_3.x86_64 （有则删除）

2.2.2. 三个节点都安装mysql

tar –xvf mysql-5.7.20-1.el6.x86_64.rpm-bundle.tar

rpm -ivh mysql-community-common-5.7.20-1.el6.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.20-1.el6.x86_64.rpm

rpm -ivh mysql-community-client-5.7.20-1.el6.x86_64.rpm

rpm -ivh mysql-community-server-5.7.20-1.el6.x86_64.rpm

2.3．设置密码

2.3.1. 编辑配置文件my.cnf

[mysqld]

server-id=157  #####这里不同

log-bin=mysql-bin   ####开启二进制日志

log-slave-updates

binlog-format=ROW

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

 

skip-external-locking

key_buffer_size = 384M

max_allowed_packet = 1M

table_open_cache = 512

sort_buffer_size = 2M

read_buffer_size = 2M

read_rnd_buffer_size = 8M

myisam_sort_buffer_size = 64M

thread_cache_size = 8

query_cache_size = 32M

 

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

 

#skip-grant-tables=1

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

 

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

2.3.2. 启动mysql

service mysqld start

2.3.3. 获取MySQL的临时密码

如果安装的是RPM包，则默认是/var/log/mysqld.log

2.3.4. 登陆并修改密码

使用默认的密码登陆:

mysql -uroot -p

 

alter user 'root'@'localhost'  identified  by  'Mysql@123456';

flush privileges;

3. 创建同步数据用户及授权用户

3.1．授权其他机器登陆

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Mysql@123456' WITH GRANT OPTION;

flush privileges;

3.2. 创建同步用户

grant replication slave on *.*  to 'mytest'@'10.60.81.%' identified by 'mytest@123';

4. mysql主主配置

4.1. 配置两台主机及启动

查看两台主机（10.60.81.157、10.60.81.158）配置文件（my.cnf）除了server-id不一样，其他几乎一模一样。配置文件写好后，我们把两台服务器上的mysql服务器启动起来

 

4.2. 登录10.60.81.157的mysql中查看master状态

mysql> show master status;

+------------------+----------+--------------+------------------+-------------------+

| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |

+------------------+----------+--------------+------------------+-------------------+

| mysql-bin.000002 |     1290 |              |                  |                   |

+------------------+----------+--------------+------------------+-------------------+

1 row in set (0.00 sec)

 

4.3. 登录10.60.81.158的msyql中，把10.60.81.157配置成自己的主

Change master to master_host='10.60.81.157',master_port=3306,master_user='mytest',master_password='mytest@123',master_log_file='mysql-bin.000002',master_log_pos=1290;

同上，查看10.60.81.158，然后登录10.60.81.157,把10.60.81.158，配置成自己的主，然后分别在两台机器的mysql中，启动slave

 

4.4. 启动10.60.81.158状态

mysql> show slave status \G;

*************************** 1. row ***************************

5．mysql主从配置

查看两台机器（10.60.81.157、10.60.81.159），把10.60.81.157作主，10.60.81.159作从，与主主配置唯一不同是，不要在主机配置从机为自己的主即可。

二、zookeeper集群搭建

1. zookeeper基本环境

操作系统： Linux version 2.6.32-431.el6.x86_64

Zookeeper:  zookeeper-3.4.12.tar.gz

三台机器：10.60.81.160、10.60.81.161、10.60.81.162

 

2. zookeeper 安装与配置

2.1．官网下载zookeeper

zookeeper-3.4.12.tar.gz

 

2.2. 上传到远程节点

scp zookeeper.tar.gz [email protected] 

scp zookeeper.tar.gz [email protected] 

scp zookeeper.tar.gz [email protected]

2.3. 登录远程节点（其他两个节点的擦作大同小异）

ssh [email protected]

 

2.4. 解压包，配置，在cnof 目录新建zoo.cfg

sz280320:cloudera-scm@/hgx/zookeeper-3.4.12/conf>cat zoo.cfg

tickTime=2000     

initLimit=5    

syncLimit=2     

dataDir=/hgx/servers/zookeeper/data      

dataLogDir=/hgx/servers/zookeeper/logs     

clientPort=4180 

server.60=10.60.81.160:2888:3888   

server.61=10.60.81.161:2888:3888     

server.62=10.60.81.162:2888:3888 

在目录上述dataDir的目录中创建myid, 将上述的三个数，server.X(我这里的X是60，61，62),中的X值写入myid文件，三台节点的myid这是不一样的。

3、zookeeper 启动与运行

3.1. 三个节点都要启动 

zookeeper/bin/zkServer.sh start

3.2、zookeeper状态检查

sz280320:cloudera-scm@/hgx/zookeeper-3.4.12/bin>./zkCli.sh -server 10.60.81.160:4180

Connecting to 10.60.81.160:4180

三、搭建HA模式的canal

1. canal基本环境

操作系统： Linux version 2.6.32-431.el6.x86_64

canal server： canal.deployer-1.0.25.tar.gz

二台机器：10.60.81.159、10.60.81.158

2．Canal安装

2.1. 官网下载Canal

canal.deployer-1.0.25.tar.gz

2.2. 新建canal用户，并赋予权限

CREATE USER canal IDENTIFIED BY 'canal';   

GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%'; 

FLUSH PRIVILEGES;

（在10.60.81.157机器中进入mysql创建canal用户，并赋予权限）

2.3. 上传包到两个远程节点

scp canal.deployer-1.0.25.tar.gz  [email protected]:/hgx/

scp canal.deployer-1.0.25.tar.gz  [email protected]:/hgx/

 

2.4．二个节点安装canal

tar –zxvf canal.deployer-1.0.25.tar.gz

mv canal.deployer-1.0.25 canal

 

3. canal配置文件

3.1. canal.properties

***上述两个配置文件，黄色标记部分为修改部分在两个服务器上一样***

4. 启动canal服务

两台机器分别执行：canal/bin/zkServer.sh

5. 查看是否启动成功

5.1. 在10.60.81.159查看日志

 

 

 

5.2. 在10.60.81.158查看日志

 

 

 

***上述两服务器日志文件(canal.log)出现如图所示，说明canal的HA搭建成功
