Mongodb 安装
为了使用mongodb副本集的某些特性，通常需要启动多个mongodb服务作为副本集成员，而在学习或者开发阶段笔记本资源比较有限。鉴于此，官方文档给了解决办法，可以直接将一个单节点mongodb服务转换为单节点副本集(standlone replica set)www.mongodb.com/docs/manual…
- 拉取镜像
[root@dawn vagrant]# docker pull mongo:6.0.2
- 启动临时容器并复制配置文件
# 权限配置
[root@dawn conf]# chown -R 999:999 /root/docker/mongodb
# 启动临时容器copy配置文件
[root@dawn data]# docker cp mongo://etc/mongod.conf.orig /root/docker/mongodb/conf/
Successfully copied 2.56kB to /root/docker/mongodb/conf/
修改配置文件
[root@dawn data]# cd ../conf
[root@dawn conf]# mv mongod.conf.orig mongod.conf
[root@dawn conf]# vim mongod.conf
storage:
dbPath: /srv/mongodb/db0
journal:

# where to write logging data.

运行容器
docker run -itd --name mongo-rs \
-p 27017:27017 \
-v /root/docker/mongodb/log:/var/log/mongodb \
-v /root/docker/mongodb/data:/srv/mongodb/db0 \
-v /root/docker/mongodb/conf/mongod.conf:/etc/mongod.conf \
mongo:6.0.2 --config /etc/mongod.conf
配置副本集
docker exec -it mongo-rs mongosh
rs.initiate()
# ---
test> rs.initiate()
{
info2: 'no configuration specified. Using a default configuration for the set',
me: 'dc4482d574a9:27017',
ok: 1
}
客户端无法连接问题
在单节点副本集下，本机既是主也是从，在容器的mongo shell中可进行查看, members只有一个成员，其name为"dc4482d574a9:27017"，而本地启动的这个副本集无法识别f76081e20602这个host。
副本集成员host的识别问题，那么在初始化mongodb副本集时，我们可以显式的去指定成员host，不使用默认的副本集配置。具体而言，将启动步骤中的第三步更改为:
rs0 [direct: primary] admin> rs.status()
{
... ...
members: [
{
_id: 0,
name: 'dc4482d574a9:27017',
health: 1,
state: 1,
stateStr: 'PRIMARY',
uptime: 215,

],
... ...
}
test> conf = {
_id : "rs0",
members: [
{ _id: 0, host: "192.168.10.200:27017" },
]
}
{ _id: 'rs0', members: [ { _id: 0, host: '192.168.10.200:27017' } ] }
test> rs.initiate(conf)
