创建keyfile

需要再docker compose yaml相同目录下执行

openssl rand -base64 756 > mongodb-keyfile

sudo chmod 600 mongodb-keyfile
sudo chown 999:999 mongodb-keyfile

# 999 可以进到容器里 cat /etc/passwd 查看mongo用户组

sudo cat ./mongo-keyfile

ls -l  查看权限

创建容器

docker-compose down -v

docker-compose up -d

docker logs mongo1

docker volume ls

初始化

bash

mongosh -u mongodb -p riSYinCCinzEzjNA --authenticationDatabase admin

rs.initiate({
    _id: "rs0",
    members: [
        { _id: 0, host: "47.121.117.97:27017" },
        { _id: 1, host: "47.121.117.97:27018" },
        { _id: 2, host: "47.121.117.97:27019" }
    ]
})

rs.status()
