我原来的数据库用的是　mysql 4.1.x ，新的是 4.0.x ，版本看起来差别不大，可是变化挺大。4.1支持每个库，每个表设置 charset，4.0还没有。4.0导入4.1好多人都乱码了。我从4.1 导入 4.0 开始也乱码了。后来搜了一下，找到一个方法，4.1 的mysqldump 有个 compactable 选项，指定是 mysql40 就行了。现在 phpmyadmin 里面看，中文也正常了。

迁移的时候顺手就换了一个 theme，弄了一天才弄好。不太喜欢这种用ftp上传的方法，都习惯用vim直接编辑文件了，本地没有环境，只能修改一下上传一次。盘古的ftp发呆时间还比较短，隔一会就得重新连接一下。感觉好墨迹。

老婆这几天一定要我写写她，可是写什么呢，她一天到晚都呆在家里，我觉得都要发霉了，让她去晒晒太阳好茁壮成长都懒得去，没办法。不过前几天她突发奇想写了一首改编自《小白兔，白又白》那个儿歌的儿歌，我贴到水木上面，加了好多个x，还是被不可re了，就看到有人发了一个帖子说“我靠，那个儿歌太x了。。。”，不过此文也被立刻删掉啦。不能re了肯定上不了十大了，也挺郁闷的，呵呵。

To start mysqld at boot time you have to copy support-files/mysql.server
to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password ‘new-password’
./bin/mysqladmin -u root -h czhand password ‘new-password’
See the manual for more instructions.

You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &

You can test the MySQL daemon with the benchmarks in the ‘sql-bench’ directory:
cd sql-bench ; perl run-all-tests

Please report any problems with the ./bin/mysqlbug script!

shell> chown -R root  .
shell> chown -R mysql data
shell> chgrp -R mysql .

/home/my.cnf

basedir=/usr/local/mysql

#err-log=/var/log/mysqld.log
pid-file=/usr/local/mysql/data/mysqld.pid

shell> bin/mysqld_safe –user=mysql &

事实上，mysql.sock放到data目录是会出现问题的，因为data目录只有mysql用户可读，用php连接数据库的时候就会出现问题。所以，上面的最好修改一下。
