搬瓦工的 64M 内存装不上 mysql 吗？

Unable to set password for the MySQL "root" user

An error occurred while setting the password for the MySQL administrative user.
This may have happened because the account already has a password, or because of
a communication problem with the MySQL server.

You should check the account's password after the package installation.

Please read the /usr/share/doc/mysql-server-5.5/README.Debian file for more
information.

我也遇到这个问题，会不会是因为内存太少了，干脆换个OS再来试试

[tpxcer]

那么小就不要装了

[yanest]

@kkxh 我试了，centos6能安装上，debian和ubuntu 不知道为啥安装不上

[yanest]

@kkxh 不过centos安装的版本是5.1，

@yanest 新版默认引擎是innodb，需要的内存提交量很大，因此你有两个选择
1. 打开内核的overcommit，然后祈祷自己内存不会爆
2. 修改mysql.cnf把默认引擎改成myisam后关闭innodb，然后再完成安装

家用电脑用64M内存的年代要追溯到20年前了，你不能总指望现代的大型软件还能在20年前的主机上正常运行吧。
