$ sudo docker pull cookeem/cookim
$ sudo docker run -d -p 8080:8080 cookeem/cookim
浏览器访问:
http://localhost:8080
如果想修改HTTP端口为18080,可以使用如下命令:
$ sudo docker run -d -p 18080:8080 cookeem/cookim
以下命令可以获取容器ID
$ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 9c353289cf37 cookeem/cookim "/root/cookim/entry.s" 4 seconds ago Up 2 seconds 0.0.0.0:8080->8080/tcp stoic_borg
运行以下命令进入容器进行调试
$ sudo docker exec -ti #CONTAINER ID# /bin/bash
以下命令停止容器
$ sudo docker stop #CONTAINER ID# $ sudo docker rm #CONTAINER ID#
进入CookIM所在目录,运行以下命令,以docker-compose方式启动CookIM集群,该集群启动了三个容器:mongodb、cookim1、cookim2
$ sudo docker-compose up -d Creating docker_mongodb_1 Creating docker_cookim1_1 Creating docker_cookim2_1
成功启动集群后,浏览器分别访问以下网址,对应不同的CookIM服务
http://localhost:8080
http://localhost:8081可以通过修改docker-compose.yml文件增加CookIM服务节点,例如增加第三个节点:
cookim3: image: cookeem/cookim-cluster volumes: - /tmp:/root/cookim/upload environment: HOST_NAME: "cookim3" WEB_PORT: "8080" AKKA_PORT: "2551" SEED_NODES: "cookim1:2551" ports: - "8082:8080" depends_on: - mongodb - cookim1
$ sudo docker-compose stop $ sudo docker-compose rm

git clone https://github.com/cookeem/CookIM.git cd CookIM
进入www目录,安装node的依赖包(npm有国内淘宝镜像,详情请百度)
$ cd www $ npm install
$ mongod &
返回CookIM目录,打开一个终端,运行如下命令,下载依赖包,该过程请耐心等待,原因你懂的(sbt有国内OSChina镜像,详情请百度)
$ cd .. $ sbt console
如果嫌sbt下载jar依赖包非常慢,我们已经预先准备好相关的jar依赖包,位于 libs
目录
启动服务有两种方式,sbt方式以及java方式
a. 进入CookIM所在目录,使用sbt方式启动服务(如果你使用sbt下载了依赖):
$ cd #CookIM directory# $ sbt "run-main com.cookeem.chat.CookIM -h localhost -w 8080 -a 2551 -s localhost:2551"
b. 进入CookIM所在目录,也可以使用java方式启动服务(如果你没有使用sbt下载依赖,而是直接用 libs
目录的依赖包启动服务):
$ cd #CookIM directory# $ java -classpath "libs/*" com.cookeem.chat.CookIM -h localhost -w 8081 -a 2552 -s localhost:2551
以上命令启动了一个监听8080端口的WEB服务,akka system的监听端口为2551
参数说明:
-a,--akka-port : akka system 监听端口2551
-h,--host-name : 外部访问本机的主机名
-n,--nat: 是否使用NAT转换,docker模式下必须设置(可选)
-s,--seed-nodes :表示akka集群的seed node监听2551端口,默认seed node为localhost:2551
http://localhost:8080
打开另外一个终端,启动另一个CookIM服务,测试服务间的消息通讯功能。
a. 进入CookIM所在目录,使用sbt方式启动服务(如果你使用sbt下载了依赖):
$ cd #CookIM directory# $ sbt "run-main com.cookeem.chat.CookIM -h localhost -w 8081 -a 2552 -s localhost:2551"
b. 进入CookIM所在目录,也可以使用java方式启动服务(如果你没有使用sbt下载依赖,而是直接用 libs
目录的依赖包启动服务):
$ cd #CookIM directory# $ java -classpath "libs/*" com.cookeem.chat.CookIM -h localhost -w 8081 -a 2552 -s localhost:2551
以上命令启动了一个监听8081端口的WEB服务,akka system的监听端口为2552
http://localhost:8081
该演示启动了两个CookIM服务,访问地址分别为8080端口以及8081端口,用户通过两个浏览器分别访问不同的的CookIM服务,用户在浏览器中通过websocket发送消息到akka集群,akka集群通过分布式的消息订阅与发布,把消息推送到集群中相应的节点,实现消息在不同服务间的分布式通讯。
akka http:用于提供web服务,浏览器通过websocket连接akka http来访问分布式聊天应用;
akka stream:akka http在接收websocket发送的消息之后(消息包括文本消息:TextMessage以及二进制文件消息:BinaryMessage),把消息放到chatService流中进行流式处理。websocket消息中包含JWT(Javascript web token),如果JWT校验不通过,chatService流会直接返回reject消息;如果JWT校验通过,chatService流会把消息发送到ChatSessionActor中;
akka cluster:akka stream把用户消息发送到akka cluster,CookIM使用到akka cluster的DistributedPubSub,当用户进入会话的时候,订阅(Subscribe)对应的会话;当用户向会话发送消息的时候,会把消息发布(Publish)到订阅的actor中,此时,群聊中的用户就可以收到消息。
websocket发送的消息体包含JWT,flowFromWS用于接收websocket消息,并把消息里边的JWT进行解码,验证有效性;
对于JWT校验失败的消息,会经过filterFailure进行过滤;对于JWT校验成功的消息,会经过filterSuccess进行过滤;
builder.materializedValue为akka stream的物化值,在akka stream创建的时候,会自动向connectedWs发送消息,connectedWs把消息转换成UserOnline消息,通过chatSinkActor发送给ChatSessionActor;
chatActorSink向chatSessionActor发送消息,在akka stream结束的时候,向down stream发送UserOffline消息;
chatSource用于接收从ChatSessionActor中回送的消息,并且把消息发送给flowAcceptBack;
flowAcceptBack提供keepAlive,保证连接不中断;
flowReject和flowAcceptBack的消息最后统一通过flowBackWs处理成websocket形式的Message通过websocket回送给用户;
users: 用户表
*login(登录邮箱) nickname(昵称) password(密码SHA1) gender(性别:未知:0,男生:1,女生:2) avatar(头像,绝对路径,/upload/avatar/201610/26/xxxx.JPG) lastLogin(最后登录时间,timstamp) loginCount(登录次数) sessionsStatus(用户相关的会话状态列表) [{sessionid: 会话id, newCount: 未读的新消息数量}] friends(用户的好友列表:[好友uuid]) dateline(注册时间,timstamp)
sessions: 会话表(记录所有群聊私聊的会话信息)
*createuid(创建者的uid) *ouid(接收者的uid,只有当私聊的时候才有效) sessionIcon(会话的icon,对于群聊有效) sessionType(会话类型:0:私聊,1:群聊) publicType(可见类型:0:不公开邀请才能加入,1:公开) sessionName(群描述) dateline(创建日期,timestamp) usersStatus(会话对应的用户uuid数组) [{uid: 用户uuid, online: 是否在线(true:在线,false:离线}] lastMsgid(最新发送的消息id) lastUpdate(最后更新时间,timstamp)
messages: 消息表(记录会话中的消息记录)
*uid(消息发送者的uid) *sessionid(所在的会话id) msgType(消息类型:) content(消息内容) fileInfo(文件内容) { filePath(文件路径) fileName(文件名) fileType(文件mimetype) fileSize(文件大小) fileThumb(缩略图) } *dateline(创建日期,timestamp)
onlines:(在线用户表)

有两个websocket信道:ws-push和ws-chat
ws-push向用户下发消息提醒,当用户不在会话中,可以提醒用户有哪些会话有新消息
/ws-push channel
上行消息,用于订阅推送消息: { userToken: "xxx" } 下行消息: acceptMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "accept", content: "xxx", dateline: "xxx" } rejectMsg: { uid: "", nickname: "", avatar: "", sessionid: "", sessionName: "", sessionIcon: "", msgType: "reject", content: "xxx", dateline: "xxx" } keepAlive: { uid: "", nickname: "", avatar: "", sessionid: "", sessionName: "", sessionIcon: "", msgType: "keepalive", content: "", dateline: "xxx" } textMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "text", content: "xxx", dateline: "xxx" } fileMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "file", filePath: "xxx", fileName: "xxx", fileSize: 999, fileType: "xxx", fileThumb: "xxx", dateline: "xxx" } onlineMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "online", content: "xxx", dateline: "xxx" } offlineMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "offline", content: "xxx", dateline: "xxx" } joinSessionMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "join", content: "xxx", dateline: "xxx" } leaveSessionMsg:{ uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "leave", content: "xxx", dateline: "xxx" } noticeMsg: { uid: "", nickname: "", avatar: "", sessionid: "", sessionName: "xxx", sessionIcon: "xxx", msgType: "system", content: "xxx", dateline: "xxx" } 下行到浏览器消息格式: pushMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "xxx", content: "xxx", fileInfo: { filePath: "xxx", fileName: "xxx", fileSize: 999, fileType: "xxx", fileThumb: "xxx" }, dateline: "xxx" }
ws-chat为用户在会话中的聊天信道,用户在会话中发送消息以及接收消息用
/ws-chat channel 上行消息: onlineMsg: { userToken: "xxx", sessionToken: "xxx", msgType:"online", content:"" } textMsg: { userToken: "xxx", sessionToken: "xxx", msgType:"text", content:"xxx" } fileMsg: { userToken: "xxx", sessionToken: "xxx", msgType:"file", fileName:"xxx", fileSize: 999, fileType: "xxx" }<#BinaryInfo#>binary_file_array_buffer 下行消息: rejectMsg: { uid: "", nickname: "", avatar: "", sessionid: "", sessionName: "", sessionIcon: "", msgType: "reject", content: "xxx", dateline: "xxx" } keepAlive: { uid: "", nickname: "", avatar: "", sessionid: "", sessionName: "", sessionIcon: "", msgType: "keepalive", content: "", dateline: "xxx" } textMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "text", content: "xxx", dateline: "xxx" } fileMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "file", filePath: "xxx", fileName: "xxx", fileSize: 999, fileType: "xxx", fileThumb: "xxx", dateline: "xxx" } onlineMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "online", content: "xxx", dateline: "xxx" } offlineMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "offline", content: "xxx", dateline: "xxx" } joinSessionMsg:{ uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "join", content: "xxx", dateline: "xxx" } leaveSessionMsg:{ uid: "xxx", nickname: "xxx", avatar: "xxx", sessionid: "xxx", sessionName: "xxx", sessionIcon: "xxx", msgType: "leave", content: "xxx", dateline: "xxx" } noticeMsg: { uid: "", nickname: "", avatar: "", sessionid: "", sessionName: "xxx", sessionIcon: "xxx", msgType: "system", content: "xxx", dateline: "xxx" } 下行到浏览器消息格式: chatMsg: { uid: "xxx", nickname: "xxx", avatar: "xxx", msgType: "xxx", content: "xxx", fileInfo: { filePath: "xxx", fileName: "xxx", fileSize: 999, fileType: "xxx", fileThumb: "xxx" }, dateline: "xxx" }
