今天在Red Hat Linux 9上面安装了MYSQL，但是在service mysql start以后，，查看service mysql status的时候出现以下提示：
mysqld 已死，但是 subsys 被锁
我起初还看了日志文件，日志文件提示：
Cannot initialize InnoDB as ‘innodb_data_file_path’ is not set.
If you do not want to use transactional InnoDB tables, add a line
skip-innodb
to the [mysqld] section of init parameters in your my.cnf
or my.ini. If you want to use InnoDB tables, add to th本文来源gaodai$ma#com搞$$代**码网e [mysqld]
section, for example,
innodb_data_file_path = ibdata1:10M:autoextend
But to get good performance you should adjust for your hardware
the InnoDB startup options listed in section 2 at
060806 12:51:01 /usr/libexec/mysqld: Incorrect information in file: ‘./mysql/host.frm’
060806 12:51:01 mysqld ended
我把原版的英文发给大家看看：
1. Obviously the ‘ole check the log file for anything nasty
cat /var/log/mysqld.log
2. Stop the service
service mysqld stop
3. Check to see if the service stopped, it might be calling the wrong pid.
ps aux | grep mysql
4. Kill any mysql process that might still be running.
kill -9 ??? ???
5. (*CAREFUL*) Remove/move/backup any databases from the data directory, only do this step if you need to.
rm -Rf /var/lib/mysql/*
6. Check your global options configuration file, should be similar to stevanbt’s initial post.
cat /etc/my.cnf
7. Copy over one of the preconfigured ‘sample’ server-specific options file. Global (/etc/my.cnf) file has priority over server-specific file, but these have more options in them and have been tuned for a certain role.
cp /usr/share/doc/mysql-server-?.??.??/my-small.cnf /var/lib/mysql
8. Recreate the initial databases, this step is optional as the initscripts will do this anyway.
mysql_install_db
9. Check and set the runlevels for the service.
chkconfig –level 345 mysqld on
chkconfig –list mysqld
10. Start the service.
service mysqld start
11. Check the log file (step 1)
Thats just a basic step through check, most of you have probably already done this.
其实做到step 9问题都已经解决了。
