mysqlclickhouse_通过mysql操作clickhouse
mysql软件安装
⾄少需要安装⼀个mysql客户端，即要有mysql这个命令；也可以直接安装⼀个mysql数据库，不⽤可以不启动；
clickhouse服务端配置mysql端⼝
vim /etc/l
9004
修改服务器端配置，需要重启clickhouse, 默认⽇志输出 /var/log/clickhouse-server/clickhouse-server.log
下⾯这种⽅式，需要在本地配置mysql，然后本地连接，默认省去的连接主机为localhost

Query OK, 0 rows affected (0.01 sec)
mysql> insert into t1 values('a01','');
Query OK, 1 row affected (0.00 sec)

1 row in set (0.01 sec)
Read 1 rows, 21.00 B in 0.002 sec., 525 rows/sec., 10.78 KiB/sec.
密码配置
为了兼容mysql客户端，建议clickhouse使⽤sha1加密算法
⽣成密码，这个⽣成命令在 /etc/l 注释部分，是官⽅给出的
# PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD"\> | sha1sum | tr -d '-' | xxd -r -p | sha1sum | tr -d '-'yOBuWUzN

删除下⾯的标签
添加新标签
1caa12e10ba19388e98b0964eb25e93128fd0ace
再次连接，不需要重启clickhouse
mysql --protocol tcp -u default -P 9004 --password=yOBuWUzN
去掉密码也可以连接
mysql --protocol tcp -u default -P 9004
