最近换环境，docker安装mysql8时报错，解决方案如下

找到 my.cnf进行修改

# 添加一下数据
[client]
# 默认字符集
#default-character-set=utf8
socket= /var/run/mysqld/mysqld.sock 

[mysql]
# 默认字符集
#default-character-set=utf8
socket= /var/run/mysqld/mysqld.sock     ####这里 对应报错 这里原来的配置在上面[client]写一份
#socket= /storage/db/mysql/mysql.sock
[mysqld]
#
server-id=01
port=3306
## 开启二进制日志功能
log-bin=mysql-slave-bin
## relay_log配置中继日志
