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：1.1 同时在线及压测客户端数量：1万1.2 每秒钟发送消息量：2300条；1.3 从发送到对方接收平均消息延时：5秒（二）群聊压测数据：2.1 群成员数量：1万人2.2 同时在线人数：1千人2.3 每秒发送消息量：500条；2.4 从发送到对方接收平均消息延时：6秒
组件集群说明
组件说明版本
etcd建议三台，可复用3.5.0
zookeeper建议三台，可复用3.7.1
mysql主从两条，可复用5.7
kafka建议三台，可复用。以2台8核16G IM Server为例说明topic分区设置，"ws2ms_chat" 8分区，"msg_to_mongo" 8分区，"ms2ps_chat" 10分区3.2.0
mongo建议2台以上，可复用。每个cache限制0.5G；多个数据分片副本集，1个mongos副本集，1个config副本集5.0
redis建议2台以上，可复用。每个内存限制10G， 淘汰策略volatile-ttl6.2.5
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
nginx配置示例
https/wss配置；负载均衡配置；以IM Server两台 127.0.0.1 127.0.0.2 ， nginx部署在其他服务器为例。
注意域名 替换ip 域名以及证书
