四、shard1安装配置
4.1、创建目录
代码语言：javascript复制mkdir -p /work/mongo-cluster/shard1/{bin,data,conf,logs,keys}4.2、编辑启动脚本
代码语言：javascript复制vim /work/mongo-cluster/shard1/bin/start.sh内容
代码语言：javascript复制docker run -d --name shard1
--network=host
--log-opt max-size=10m
-v /etc/timezone:/etc/timezone
-v /etc/localtime:/etc/localtime
-v /work/mongo-cluster/shard1/data:/data
-v /work/mongo-cluster/shard1/keys:/keys
-v /work/mongo-cluster/shard1/logs:/var/log/mongodb
-v /work/mongo-cluster/shard1/conf/mongod.conf:/etc/mongo/mongod.conf
mongo:4.2.5 --config /etc/mongo/mongod.conf chmod 755 /work/mongo-cluster/shard1/bin/start.sh4.3、编辑配置文件
代码语言：javascript复制vim /work/mongo-cluster/shard1/conf/mongod.conf内容
代码语言：javascript复制# mongod.conf

}4.9、创建shard本地管理用户
该用户在集群中不可见，用于管理shard节点
代码语言：javascript复制admin = db.getSiblingDB("admin")
admin.createUser(
{
user: "shard1admin",
pwd: "q1w2e3r4",
roles: [ { role: "root", db: "admin" } ]
}
)返回值类似
代码语言：javascript复制Successfully added user: {
"user" : "shard1admin",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}
