具体修改安装目录即可
3）初始化数据，会生成一个root@localhost的账号，密码为空
bin/mysqld --defaults-file=${MYSQl_NAME}/my.cnf --initialize-insecure
目录下面会出现data目录；服务并没有启动
4)bin/mysqld --defaults-file=${MYSQl_NAME}/my.cnf 启动服务
5)然后使用命令修改用户名密码
bin/mysqladmin -uroot password‘123456‘ --socket=mysql.sock
6)会用命令登录
bin/mysql --socket=./mysql.sock -uroot -p‘123456‘
正常访问即可
7）数据库备份
bin/mysqldump -uroot -p123456 -h192.168.0.70 Webgate >./backup.sql
还原：
bin/mysqldump -uroot -p123456 -h192.168.0.70 Webgate <./backup.sql
8)mysql编码
如果 表中有中文字符，需要注意编码问题
首先执行环境下的编码格式为：export LANG=zh_CN.UTF8
然后修改：my.cnf中配置文件：
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
9)执行sql文件有两种方式
bin/mysql -uroot -p123456 --socket=./mysql.sock <create-table.sql
或者进入mysqlshell
mysql> source /home/bes/mysql.sql
