启动3个节点:
mongod -f /mongodb/38018/conf/mongod.conf
mongod -f /mongodb/38019/conf/mongod.conf
mongod -f /mongodb/38020/conf/mongod.conf

搭建-一主二从:
mongo --port 38018 admin
config ={_id: 'configReplSet',members: [
{_id: 0,host:'192.168.137.5:38018'},
{_id: 1,host:'192.168.137.5:38019'},

初始化集群:
rs.initiate(config)

启动MONGOS:
mongos -f /mongodb/38017/conf/mongos.conf

分片集群添加节点:
mongo 192.168.137.5:38017/admin

ps -ef | grep mongo -- 有10个进程

分片集群添加节点:
mongo 192.168.137.5:38017/admin

添加分片:
db.runCommand({addshard: "sh1/192.168.137.5:38021,192.168.137.5:38022,192.168.137.5:38023",name:"shard1"})

列出分片:
db.runCommand({listshards:1})

整体的状态
sh.status();

tail -100 /var/log/mysqld.log 找密码

mysql8设置密码策略:
set global validate_password.policy=0;
set global validate_password.length=4;
set global validate_password.check_user_name=OFF;
set global validate_password.number_count=0;

alter user user() identified by "root";
