免安装版的mysql5.7.17里面的mysqlserver.lib1G多,可以删除吗

: 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

shell>groupadd mysql

shell>useradd -r -g mysql mysql

shell>cd /usr/local

shell>tar zxvf mysql-5.5.32-linux2.6-x86_64.tar.gz

shell>mv mysql-5.5.32-linux2.6-x86_64 /usr/local/mysql3309

shell>cd /usr/local/mysql3309

shell>chown -R mysql .

shell>chgrp -R mysql .

2

shell>cat my3309.cnf

#/usr/local/mysql3309下新建my3309.cnf配置文件,内容复制my3308.cnf

shell>mkdir /usr/local/mysql3309/logs

shell>mkdir /usr/local/mysql3309/bin-log

shell>chown -R mysql.mysql .

shell>scripts/mysql_install_db --user=mysql --defaults-file=/usr/local/mysql3309/my3309.cnf

(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

4

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
