: 1.解压到自定义目录:我解压到了D盘的根目录
2.复制my-default.ini 重命名 my.ini
编译出来的空的mysql有1G这么大在my.ini最底下添加个KV对:
max_allowed_packet=100000M
然后重启Mysql,就可以按普通的方法导了,可以用mysql命令,也可以用navicat for mysql(我一般用这个)
不知道能不能写成100G,没试过,LZ试下吧。
如果改不了my.ini可以试试这个方法,我没试过,因为我一直是改my.ini的,相信你有这么大的数据库应该不是用的虚拟主机吧:
set global max_allowed_packet = 100*1024*1024*1024
然后用:
show VARIABLES like '%max_allowed_packet%'
查看一下是否修改成功,这个应该就不用重启mysql了

(启动mysql)
shell>bin/mysqld_safe --defaults-file=/usr/local/mysql3309/my3309.cnf --user=mysql >/dev/null 2>&1 &
(进入mysql)
shell>bin/mysql --defaults-file=/usr/local/mysql3309/my3309.cnf

无法启动或进入:
查看日志shell>tail -f /usr/local/mysql3309/logs/mysql3309.log
END
注意事项
解压缩版的mysql可直接运行,执行时需指定my.cnf文件
注意添加--defaults-file=/usr/local/my3309.cnf命令
由于在my.cnf文件中指定了mysql.sock的位置,为了避免多个mysql同时读取/tmp/mysql.sock文件,在启动时指定读取的sock文件位置: --socket=/tmp/mysql3307.sock
