七、mongos安装配置
7.1、创建目录
代码语言：javascript复制mkdir -p /work/mongo-cluster/mongos/{bin,data,conf,logs,keys}7.2、编辑启动脚本
代码语言：javascript复制vim /work/mongo-cluster/mongos/bin/start.sh内容
代码语言：javascript复制docker run -d --name mongos
--network=host
--log-opt max-size=10m
-v /etc/timezone:/etc/timezone
-v /etc/localtime:/etc/localtime
-v /work/mongo-cluster/mongos/data:/data
-v /work/mongo-cluster/mongos/keys:/keys
-v /work/mongo-cluster/mongos/logs:/var/log/mongodb
-v /work/mongo-cluster/mongos/conf/mongod.conf:/etc/mongo/mongod.conf
mongo:4.2.5 mongos -f /etc/mongo/mongod.conf chmod 755 /work/mongo-cluster/mongos/bin/start.sh7.3、编辑配置文件
代码语言：javascript复制vim /work/mongo-cluster/mongos/conf/mongod.conf内容
代码语言：javascript复制# mongod.conf

## Enterprise-Only Options:
#auditLog:

代码语言：javascript复制cp ~/mongo-cluster.key /work/mongo-cluster/mongos/keys/
sudo chown 999 /work/mongo-cluster/mongos/keys/mongo-cluster.key
sudo chmod 400 /work/mongo-cluster/mongos/keys/mongo-cluster.key7.5、设置目录权限
代码语言：javascript复制sudo chown 999 /work/mongo-cluster/mongos/data/ /work/mongo-cluster/mongos/logs/7.6、启动应用
代码语言：javascript复制/work/mongo-cluster/mongos/bin/start.sh7.7、创建管理用户
连接任意节点
代码语言：javascript复制docker exec -it mongos mongo --port 27017创建用户，该用户在集群环境中可见（相当于单机版root用户，用于创建用户，数据库等操作）
代码语言：javascript复制db.getSiblingDB("admin").createUser(
{
"user" : "root",
"pwd" : "q1w2e3r4",
roles: [ { "role" : "root", "db" : "admin" } ]
}
)返回值
代码语言：javascript复制Successfully added user: {
"user" : "root",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}7.8、将分片加入集群
连接任意节点
代码语言：javascript复制docker exec -it mongos mongo --port 27017管理用户验证，使用你的密码替换
代码语言：javascript复制use admin
db.auth("root","q1w2e3r4")添加shard1
代码语言：javascript复制sh.addShard("shard1/172.30.3.231:27019,172.30.3.234:27019,172.30.3.238:27019");返回值
代码语言：javascript复制{
"shardAdded" : "shard1",
"ok" : 1,
"operationTime" : Timestamp(1586591415, 6),
"$clusterTime" : {
"clusterTime" : Timestamp(1586591415, 6),

"keyId" : NumberLong("6814344100507025437")
}
}
}添加shard2
代码语言：javascript复制sh.addShard("shard2/172.30.3.231:27020,172.30.3.234:27020,172.30.3.238:27020");返回值
代码语言：javascript复制{
"shardAdded" : "shard2",
"ok" : 1,
"operationTime" : Timestamp(1586591430, 3),
"$clusterTime" : {
"clusterTime" : Timestamp(1586591430, 3),
"signature" : {
"hash" : BinData(0,"JZW45knbJ2Lc8fEEBuA AIxgAxI="),
"keyId" : NumberLong("6814344100507025437")
}
}
}添加shard3
代码语言：javascript复制sh.addShard("shard3/172.30.3.231:27021,172.30.3.234:27021,172.30.3.238:27021");返回值
代码语言：javascript复制{
"shardAdded" : "shard3",
"ok" : 1,
"operationTime" : Timestamp(1586591443, 5),
"$clusterTime" : {
"clusterTime" : Timestamp(1586591443, 5),
"signature" : {

"keyId" : NumberLong("6814344100507025437")
}
}
}7.9、查询状态
代码语言：javascript复制sh.status()返回值
