IM开源项目OpenIM集群（非k8s）部署文档生产环境可参考

　　自行部署etcd/zookeeper/mysql/kafka/mongo/redis集群，可以根据此性能评估服务器需求。
　　以下是针对一台华为云主机s3的压测数据：8核16G内存，普通磁盘（非SSD）
　　（一）单聊压测数据：
　　同时在线及压测客户端数量：1万
　　每秒钟发送消息量：2300条；
　　从发送到对方接收平均消息延时：5秒
　　（二）群聊压测数据：
　　群成员数量：1万人
　　同时在线人数：1千人
　　每秒发送消息量：500条；
　　从发送到对方接收平均消息延时：6秒

　　6.2.5  IM Server集群部署（1）下载代码及编译git clone https://github.com/OpenIMSDK/Open-IM-Server.git --recursive cd Open-IM-server/script chmod +x *.sh ./batch_build_all_service.sh  出现all services build success表示所有模块编译成功（2）修改组件信息kafka:   ws2mschat:     addr: [ 127.0.0.1:9092, 127.0.0.2:9092, 127.0.0.3:9092 ] #     topic: ＂ws2ms_chat＂ open_im_msg写入，open_im_msg_transfer消费后新消息入库redis和kafka ＂msg_to_mongo＂ 、 ＂ms2ps_chat＂   ws2mschatoffline:     addr: [  127.0.0.1:9092, 127.0.0.2:9092, 127.0.0.3:9092 ] #kafka配置，默认即可     topic: ＂ws2ms_chat_offline＂ 不再使用   msgtomongo:     addr: [  127.0.0.1:9092, 127.0.0.2:9092, 127.0.0.3:9092 ] #kafka配置，默认即可     topic: ＂msg_to_mongo＂  open_im_msg_transfer消费历史消息入库mongo   ms2pschat:     addr: [  127.0.0.1:9092, 127.0.0.2:9092, 127.0.0.3:9092 ] #kafka配置，默认即可     topic: ＂ms2ps_chat＂  open_im_push消费，推送消息到open_im_msg_gateway  etcd:   etcdSchema: openim  #默认即可   etcdAddr: [ 127.0.0.1:2379, 127.0.0.2:2379, 127.0.0.3:2379] #etcd集群  mysql:   dbMysqlAddress: [ 127.0.0.1:13306,  127.0.0.2:13306] #mysql主备    mongo:   dbAddress: [127.0.0.1:37017, 127.0.0.2:37017, 127.0.0.3:37017]  #使用分片集群时为mongos地址  redis:   dbAddress: [ 127.0.0.1:16379, 127.0.0.2:16379, 127.0.0.3:16379 ] #redis集群    rpcRegisterIP:#不要填写 （3）调整进程数
　　open_im_msg 6个，open_im_push 5个 openImMessagePort: [ 10130, 10131, 10132, 10133, 10134,10135 ] #open_im_msg 配置6个端口则启动6个进程 openImPushPort: [ 10170, 10171, 10172, 10173, 10174 ] #open_im_push 配置5个端口则启动5个进程
　　open_im_msg_transfer 4个 修改script/path_info.cfg msg_transfer_name=＂open_im_msg_transfer＂ msg_transfer_binary_root=＂../bin/＂ msg_transfer_source_root=＂../cmd/open_im_msg_transfer/＂ msg_transfer_service_num=4（4）复制Open-IM-Server到其他服务器scp -r Open-IM-Server root@127.0.0.2:/data（5）启动cd script ./start_all.sh 关于OpenIM
　　OpenIM是由IM技术专家打造开源即时通讯组件，也是目前最受欢迎的开源IM项目之一，开发者通过集成OpenIM组件，并私有化部署服务端，可以将即时通讯、实时通讯能力快速集成到自身应用中，并确保业务数据的安全性和私密性。github社区活跃，star近万，排名遥遥领先，开发者万人，OpenM力争开源IM项目No1，打造开源IM第一社区。OpenIM是也是目前非常受欢迎的开源IM项目，广泛用于政企协同办公场景。
