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;

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 root@10.60.81.161
scp zookeeper.tar.gz root@10.60.81.161
scp zookeeper.tar.gz root@10.60.81.162
2.3. 登录远程节点（其他两个节点的擦作大同小异）
ssh root@192.168.213.44
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 root@10.60.81.159:/hgx/
scp canal.deployer-1.0.25.tar.gz root@10.60.81.158:/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
