第一步：创建4个容器
docker run -itd -p 11810:11810 -p 11800:11800 -p 8000:8000 -p 11790:11790 -p 11780:11780 --privileged=true --restart=always -v /nodedata/sequoiadb/master_data:/opt/sequoiadb/database --name coord_catalog1 --hostname coord_catalog1 sequoiadb/sequoiadb:latest docker run -itd -p 11820:11820 -p 11830:11830 -p 11840:11840 --privileged=true --restart=always -v /nodedata/sequoiadb/sdb_data1:/opt/sequoiadb/database --name sdb_data1 --hostname sdb_data1 sequoiadb/sequoiadb:latest
docker run -itd -p 11810:11810 -p 11800:11800 -p 8000:8000 -p 11790:11790 -p 11780:11780 --privileged=true --restart=always -v /nodedata/sequoiadb/master_data:/opt/sequoiadb/database --name coord_catalog2 --hostname coord_catalog2 sequoiadb/sequoiadb:latest
docker run -itd -p 11820:11820 -p 11830:11830 -p 11840:11840 --privileged=true --restart=always -v /nodedata/sequoiadb/sdb_data2:/opt/sequoiadb/database --name sdb_data2 --hostname sdb_data2 sequoiadb/sequoiadb:latest
docker run -itd -p 11810:11810 -p 11800:11800 -p 8000:8000 -p 11790:11790 -p 11780:11780 --privileged=true --restart=always -v /nodedata/sequoiadb/master_data:/opt/sequoiadb/database --name coord_catalog3 --hostname coord_catalog3 sequoiadb/sequoiadb:latest
docker run -itd -p 11820:11820 -p 11830:11830 -p 11840:11840 --privileged=true --restart=always -v /nodedata/sequoiadb/sdb_data3:/opt/sequoiadb/database --name sdb_data3 --hostname sdb_data3 sequoiadb/sequoiadb:latest
查看4个容器的ip地址
docker inspect coord_catalog | grep IPAddress |awk 'NR==2 {print $0}' docker inspect sdb_data1 | grep IPAddress |awk 'NR==2 {print $0}' docker inspect sdb_data2 | grep IPAddress |awk 'NR==2 {print $0}' docker inspect sdb_data3 | grep IPAddress |awk 'NR==2 {print $0}'
1 、修改database目录权限 chown sdbadmin database/ chgrp sdbadmin_group database/ 2、修改/etc/hosts 192.168.2.194 coord_catalog1 192.168.2.196 sdb_data1 192.168.2.131 coord_catalog2 192.168.2.134 sdb_data2 192.168.2.66 coord_catalog3 192.168.2.69 sdb_data3 192.168.2.195 mysql_bsxq_m1 192.168.2.130 mysql_bsxq_m2
-------------编码和编辑节点均高可用-----------------------------------
docker exec coord_catalog "/init.sh"
--coord='coord_catalog1:11810,coord_catalog2:11810,coord_catalog3:11810'
--catalog='coord_catalog1:11800,coord_catalog2:11800,coord_catalog3:11800'
--data='group1=sdb_data1:11820,sdb_data2:11820,sdb_data3:11820;group2=sdb_data2:11830,sdb_data3:11830,sdb_data1:11830;group3=sdb_data3:11840,sdb_data1:11840,sdb_data2:11840'
输出：************ Deploy SequoiaDB ************************ ************ Deploy SequoiaDB ************************ Create catalog: coord_catalog1:11800 Create catalog: coord_catalog2:11800 Create catalog: coord_catalog3:11800 Create coord: coord_catalog1:11810 Create coord: coord_catalog2:11810 Create coord: coord_catalog3:11810 Create data: sdb_data1:11820 Create data: sdb_data2:11820 Create data: sdb_data3:11820 Create data: sdb_data2:11830 Create data: sdb_data3:11830 Create data: sdb_data1:11830 Create data: sdb_data3:11840 Create data: sdb_data1:11840 Create data: sdb_data2:11840
第三步：创建mysql容器 //主节点 docker run -itd -p 3306:3306 -v /nodedata/sequoiadb/mysql:/opt/sequoiasql/mysql/database --privileged=true --name mysql_bsxq_m1 --hostname mysql_bsxq_m1 sequoiadb/sequoiasql-mysql:latest //可作为读节点 docker run -itd -p 3306:3306 -v /nodedata/sequoiadb/mysql:/opt/sequoiasql/mysql/database --privileged=true --name mysql_bsxq_m2 --hostname mysql_bsxq_m2 sequoiadb/sequoiasql-mysql:latest 查看容器ip地址 $ docker inspect mysql_bsxq | grep IPAddress | awk 'NR==2 {print $0}' 第四步：将 MySQL 实例注册入协调节点 chown sdbadmin database/ chgrp sdbadmin_group database/ 在opt/sequoiasql/mysql 路径下 mkdir binlog chown sdbadmin binlog/ chgrp sdbadmin_group binlog/ docker exec mysql_master "/init.sh" --port=3306 --coord='coord_catalog1:11810'
service sequoiasql-mysql status
【问题描述】
用户通过快速部署安装集群，没有安装 SAC 服务。所以问能否再单独安装 SAC 服务？
【解决办法】
在集群的所有机器上执行命令：“ps -ef | grep sdbom”，查看机器上是否有SAC服务进程。如果是通过快速部署的方式启动的集群，那应该是没有这个进程的。确认没有SAC服务进程后，执行以下步骤：
- 启动SAC服务进程，在sdb shell执行命令：
var oma = new Oma( "localhost", 11790 )
oma.createOM( 11780, "/opt/sequoiadb/database/sms/11780", { httpname: 8000, wwwpath: "/opt/sequoiadb/web" } )
oma.startNode( 11780 )
- 将sequoiadb.xxx.run包和sequoiasql.xxx.run包拷贝到目录“/opt/sequoiadb/packet”下，并赋予它们可读权限
- 此时SAC服务进程已经准备就绪，接下来进行web端操作。SAC服务进程只需要在一台机器上运行即可，目前它不是分布式的
SAC单独安装，在3.0版本以前可以发现SequoiaDB存储服务，但是无法发现SQL实例，在3.2.2版本之后才有发现SQL实例的功能
mysql 双主架构 https://www.cnblogs.com/zping/p/7928805.html GRANT REPLICATION SLAVE ON . TO 'RepUser'@'%'identified by 'bsxq123456';
查看serverid show variables like 'ser%'; 查看是否开启binlog 重启mysql后 show variables like '%log_bin%'； Value 为 ON即可
查询binlog 变动信息 show binlog events; auto.cnf master1 ########## add by huanglin server_id = 1 # 两天机器的serverid不能相同。 log-bin = /opt/sequoiasql/mysql/binlog/mysql-bin binlog_format = mixed relay-log=/opt/sequoiasql/mysql/binlog/bsxq-reply-bin relay-log-index=/opt/sequoiasql/mysql/binlog/bsxq-reply-bin.index auto-increment-offset = 1 auto-increment-increment = 1
master2 ########## add by huanglin server_id=3 log-bin = /opt/sequoiasql/mysql/binlog/mysql-bin binlog_format = mixed relay-log=/opt/sequoiasql/mysql/binlog/master1-reply-bin relay-log-index=/opt/sequoiasql/mysql/binlog/master1-reply-bin.index auto-increment-offset = 1 auto-increment-increment = 1 log-slave-updates=true
CHANGE MASTER TO MASTER_USER='RepUser',MASTER_HOST='mysql_bsxq_m1',MASTER_PASSWORD='bsxq123456',MASTER_PORT=3306,MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=437;
CHANGE MASTER TO MASTER_USER='RepUser',MASTER_HOST='mysql_bsxq_m2',MASTER_PASSWORD='bsxq123456',MASTER_PORT=3306,MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=437;
常用命令：
start slave; stop salve; show slave status\G; show table status; show master status; show full processlist;
