无聊，自建轮子
创建mongo镜像,dockerfile如下
from centos:7 RUN yum install net-tools vim -y RUN mkdir -p /mongodb/bin && mkdir -p /mongodb/conf && mkdir -p /mongodb/log && touch /mongodb/log/mongodb.log && mkdir -p /mongodb/data && chmod 755 /mongodb -R ENV MONGOD_HOME /mongodb ENV PATH $MONGOD_HOME/bin:$PATH COPY ./mongodb/bin/ /mongodb/bin/ COPY mongod.conf /mongodb/conf/mongod.conf COPY run.sh /mongodb/bin/run.sh RUN chmod a+x /mongodb/bin/run.sh CMD ["/mongodb/bin/run.sh"]
run.sh如下
#!/bin/bash echo "######启动程序##########" mongod -f /mongodb/conf/mongod.conf echo "######查看端口##########" netstat -ntulp echo "######查看进程##########" ps -ef |grep -v grep |grep mongod while true do sleep 1h done
mongod.conf如下
systemLog: destination: file path: /mongodb/log/mongodb.log logAppend: true storage: journal: enabled: true dbPath: /mongodb/data directoryPerDB: true #engine: wiredTiger wiredTiger: engineConfig: # cacheSizeGB: 1 directoryForIndexes: true collectionConfig: blockCompressor: zlib indexConfig: prefixCompression: true processManagement: fork: true net: bindIpAll: true port: 27017 replication: oplogSizeMB: 2048 replSetName: my_repl
docker-compose.yml如下，ip说明：我单机创建的虚拟网
version: ‘3.4‘ x-logging: &default-logging options: max-size: ‘12m‘ max-file: ‘5‘ driver: json-file services: mongo1: image: mongo:v15 logging: *default-logging restart: always hostname: mongo1 networks: doufy: ipv4_address: 172.19.0.71 volumes: - /etc/localtime:/etc/localtime:ro - /data/mongo/1/data:/mongodb/data - /data/mongo/1/log:/mongodb/log mongo2: image: mongo:v15 logging: *default-logging restart: always hostname: mongo2 networks: doufy: ipv4_address: 172.19.0.72 volumes: - /etc/localtime:/etc/localtime:ro - /data/mongo/2/data:/mongodb/data - /data/mongo/2/log:/mongodb/log mongo3: image: mongo:v15 logging: *default-logging restart: always hostname: mongo3 networks: doufy: ipv4_address: 172.19.0.73 volumes: - /etc/localtime:/etc/localtime:ro - /data/mongo/3/data:/mongodb/data - /data/mongo/3/log:/mongodb/log networks: doufy: external: true
mongodb为官网下载，版本为4.2
链接 https://www.mongodb.com/download-center/enterprise
具体配置参考配置文件。
创建复制集群
登陆数据库，配置mongodb复制
shell> mongo --port 27017
config = {_id: ‘my_repl‘, members: [
{_id: 0, host: ‘172.19.0.71:27017‘},
{_id: 1, host: ‘172.19.0.72:27017‘},
{_id: 2, host: ‘172.19.0.73:27017‘}]
}
初始化这个配置
> rs.initiate(config)
查看状态,数据库已变为 PRIMARY或者SECONDARY（下面标红部分）,rs.status可查看具体配置信息

到此复制集配置完成，分片学习中，后续更新
