如何在1台服务器手动部署2个OB节点

OceanBase
#1

【 使用环境 】测试环境
【 OB or 其他组件 】OB
【 使用版本 】3.1.3-OceanBase CE
【问题描述】使用OBD可以在1台服务器部署2个OB节点，如何用手动部署在1台服务器部署2个OB节点？
【复现路径】
【问题现象及影响】将oceanbase目录下的文件拷贝到observer1和observer4目录内，手动启动observer，但是只有1个pid。

你第二次起的port和第一次起的port的命令是一样的，冲突了吧？-p 2881 -P 2882

bin/observer -i ens192 -p 2881 -P 2882 -z zone1 -d ~/njob/observer1/store -r ‘10.11.144.11:2882:2881’ -c 2023 -n njob -l WARN -o “memory_limit=12G,cache_wash_threshold=1G,__min_full_resource_pool_memory=268435456,system_memory=2G,memory_chunk_cache_size=128M,cpu_count=16,net_thread_count=4,datafile_size=30G,stack_size=1536K”

6个observer都起来了，但是初始化集群报错，麻烦看一下。

bootstrap 的时候 从 1-1-1 开始，成功了 再 用add server 扩容到 2-2-2 。
这样成功概率高一些。
