mysql5.7.10

5.7.10问题

复制／support-file/my-default.cnf  修改并重命名my.cnf 
修改
basedir = /usr/local/mysql
  datadir = /usr/local/mysql/data
port = 3306
# server_id = .....
  socket = /tmp/mysql.socket


Can't read from message file errmsg.sys？
解决
复制  mysql 二进制解压缩包下的share/errmsg.sys 到datadir下（/usr/local/mysql/data/errmag.sys）

初始化：
./mysqld --defaults-file=/local/mysql-5.7.10-linux-glibc2.5-x86_64/support-files/my.cnf --initialize --user=mysql

Please read "Security" section of the manual to find out how to run mysqld as root!
这个版本mysql不允许用户直接操作root权限，./mysqld --user=root来强制启动
