ubuntu安装mysql时遇到的问题

1. sudo scripts/mysql_install_db --user=mysql
   出现FATAL ERROR: Neither host 'David' nor 'localhost' could be looked up with /usr/bin/resolveip
   Please configure the 'hostname' command to return a correct hostname.

把mysql目录下bin里面的resolveip复制到/usr/bin/下

2. 再次启动后出现
   [ERROR] Can't find messagefile '/usr/share/mysql/errmsg.sys'

将mysql目录下share/english/errmsg.sys复制到/usr/share/mysql

3. sudo bin/mysqld_safe --user=mysql &启动mysql服务后，打开另一个终端，bin/mysql可以进入mysql控制台，但是使用sudo ./bin/mysql_secure_installation修改root密码时，出现ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (13)，此时使用sudo ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock建立软连接后，即可使用
