如何手动部署 OceanBase 集群(三节点)

2024年 5月 7日 55.7k 0

本次测试使用单台服务,启动3个observer服务模拟,从单节点扩容到三节点操作。

服务器信息:

zone1 192.168.5.200 2881 2882

zone2 192.168.5.200 3881 3882

zone3 192.168.5.200 4881 4882

1 系统版本系统

cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)

2 空间要求

/data磁盘组大于150G

内存大于30G

3 系统初始化,软件安装相关内容参考

https://www.modb.pro/db/190763

4 建立相关数据目录

mkdir -p /data/{observer01,observer02,observer03,obproxy}
mkdir -p /data/observer{01,02,03}/store/{sort_dir,sstable,clog,ilog,slog}

5 启动zone1的observer,并初始化

#启动observer
cd /data/observer01/ && /home/admin/oceanbase/bin/observer -r "192.168.5.200:2882:2881" -o __min_full_resource_pool_memory=268435456,memory_limit=8G,system_memory=4G,stack_size=512K,cpu_count=16,cache_wash_threshold=1G,workers_per_cpu_quota=10,schema_history_expire_time=1d,net_thread_count=4,sys_bkgd_migration_retry_num=3,minor_freeze_times=10,enable_separate_sys_clog=0,enable_merge_by_turn=False,datafile_size=50G,enable_syslog_recycle=True,max_syslog_file_count=10 -z zone1 -p 2881 -P 2882 -c 1 -d /data/observer01/store -i ens192 -l INFO

#初始化集群
obclient -h 192.168.5.200 -u root -P 2881 -p -c -A
set session ob_query_timeout=1000000000; alter system bootstrap ZONE 'zone1' SERVER '192.168.5.200:2882';
