初始化mongo 数据目录
# 初始化文件目录
mkdir ${mongo_path}
mkdir ${mongo_path}/log
cd ${mongo_path}
# 初始化 keyFile 和 mongodb.cnf(配置文件)
echo "XXXXXXXX" > keyFile
chmod 4000 keyFile

启动mongo
sudo -u mongo numactl --interleave=all /usr/local/mongodb/bin/mongod -f ${mongo_path}/mongodb.cnf &>/dev/null
配置副本集

启动master 节点
# 启动节点
sudo -u mongo numactl --interleave=all /usr/local/mongodb/bin/mongod -f ${mongo_path}/mongodb.cnf &>/dev/null
# 配置副本集参数
/usr/local/mongodb/bin/mongo 127.0.0.1:${mongo_port}/admin --eval 'rs.initiate('{_id:"${mongo_port}",version:1,writeConcernMajorityJournalDefault:false,members:[{_id:0,host:"${mongo_node_ip}:${mongo_port}"}],settings:{getLastErrorDefaults:{w:"majority",wtimeout:3000}}}')'
# 配置初始化系统用户
/usr/local/mongodb/bin/mongo 127.0.0.1:${mongo_port}/admin --eval 'db.createUser({user: "dba",pwd: "dba",roles:["__system"]})'
# 添加管理超级用户

# 删除初始化用户
/usr/local/mongodb/bin/mongo 127.0.0.1:${mongo_port}/admin -u dba -p dba --eval 'db.dropUser("dba")'
# kill 掉之前进程 重新启动节点
ps aux | grep mongo
kill xxxxx
sudo -u mongo numactl --interleave=all /usr/local/mongodb/bin/mongod -f ${mongo_path}/mongodb.cnf &>/dev/null
#认证降级，3.6及其以上版本不需要做认证降级
/usr/local/mongodb/bin/mongo 127.0.0.1:${mongo_port}/admin -u dba -p dba --eval 'db.system.version.save({ "_id" : "authSchema", "currentVersion" : 3 })'
启动从节点
# 启动节点
sudo -u mongo numactl --interleave=all /usr/local/mongodb/bin/mongod -f ${mongo_path}/mongodb.cnf &>/dev/null
# 去主节点添加从节点信息
/usr/local/mongodb/bin/mongo ${master_ip}:${mongo_port}/admin -u ${mongo_user} -p ${mongo_pwd} --eval 'rs.add("${mongo_node_ip}:${mongo_port}")'

启动步骤
1.先部署两个分片节点 (步骤参考上文配置副本集节点)
2.再部署config server 节点 (步骤参考上文配置副本集节点)
3.最后再部署mongos 路由节点
# 启动节点
sudo -u mongo numactl --interleave=all /usr/local/mongodb/bin/mongod -f ${mongo_path}/mongodb.cnf &>/dev/null
# 添加2个分片节点
/usr/local/mongodb/bin/mongo 127.0.0.1:${mongo_port}/admin -u dba -p dba --eval 'sh.addShard("${mongo_replSet}/${mongo_shards_node1}:${mongo_shards_port},${mongo_shards_node2}:${mongo_shards_port},${mongo_shards_node3}:${mongo_shards_port}")'
