docker中使用mongodb数据库详解(在局域网访问)
前言
有了docker,基本上就告别了各种软件、数据库的安装,直接从镜像库pull下来,爽,想想以前那真是一个遭罪啊。
这文章就来看一下如何跑mongo的docker镜像,并且可以在局域网访问,内容相对简单,也是记录我的自学过程。
第一步
获得mongo镜像,命令如下,
# 拉取mongo镜像 docker pull mongo # 查看本地库mongo镜像 docker images mongo
第二步
启动mongo镜像,如下
# 启动mongo镜像 docker run -itd -P --name mongo-server mongo bash # 查看mongo进程 docker ps -a
第三步
进入容器并启动mongo,如下
# 进入mongo容器,其中‘mongo-server'是mongo容器别名 docker exec -it mongo-server bash # 启动mongo服务 mongod & # 在容器中查看mongo进程 ps -ef | grep mongo
启动以后会看到如下日志(最后几行),
2017-06-13T07:25:56.318+0000 I FTDC [initandlisten] Initializing full-time diagnostic data capture with directory '/data/db/diagnostic.data' 2017-06-13T07:25:56.328+0000 I INDEX [initandlisten] build index on: admin.system.version properties: { v: 2, key: { version: 1 }, name: "incompatible_with_version_32", ns: "admin.system.version" } 2017-06-13T07:25:56.328+0000 I INDEX [initandlisten] building index using bulk method; build may temporarily use up to 500 megabytes of RAM 2017-06-13T07:25:56.329+0000 I INDEX [initandlisten] build index done. scanned 0 total records. 0 secs 2017-06-13T07:25:56.329+0000 I COMMAND [initandlisten] setting featureCompatibilityVersion to 3.4 2017-06-13T07:25:56.329+0000 I NETWORK [thread1] waiting for connections on port 27017
第四步
本地验证测试,输入mongo启动mongo命令行客户端,如下内容
root@01ff7ed6377c:/# mongo MongoDB shell version v3.4.4 connecting to: mongodb://127.0.0.1:27017 2017-06-13T07:34:00.289+0000 I NETWORK [thread1] connection accepted from 127.0.0.1:55650 #2 (1 connection now open) 2017-06-13T07:34:00.290+0000 I NETWORK [conn2] received client metadata from 127.0.0.1:55650 conn2: { application: { name: "MongoDB Shell" }, driver: { name: "MongoDB Internal Client", version: "3.4.4" }, os: { type: "Linux", name: "PRETTY_NAME="Debian GNU/Linux 8 (jessie)"", architecture: "x86_64", version: "Kernel 3.10.0-327.28.3.el7.x86_64" } }
接着输入测试命令,
> show dbs; admin 0.000GB local 0.000GB >
第五步
在局域网访问docker中的mongo,由于启动的时候是使用的随机端口映射,意思是宿主机产生一个随机端口去映射mongo的27017端口,通过‘docker ps -a'
命令查看宿主机随机端口,如下,
docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 01ff7ed6377c mongo "docker-entrypoint.sh" 15 minutes ago Up 15 minutes 0.0.0.0:32773->27017/tcp mongo-server
如上,宿主机随机端口为32773,通过配置robomongo客户端连接mongo,如下,
结果正常。
如果要停止mongo可以使用如下命令,
# 登入mongo mongo # 选择使用admin库,在其他的库不行 use admin # 关闭mongo db.shutdownServer()
通过‘ps -ef | grep momgo'
查看mongo进程是否存在,如果不存在说明关闭成功。
