# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /usr/local/mysql/var) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
# The following options will be passed to all MySQL clients

[client]
default-character-set = utf8
#password    = your_password

# if all processes that need to connect to mysqld run on the same host.

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id    = 1
# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
  # overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id    = 2
#
# The replication master for this slave - required
#master-host    = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user    = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port    =  <port>

那也就是说你做的是升级mysql的操作咯？
那就按照提示所说的[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
运行一下mysql_upgrade,具体的参数可以man一下。

还有[ERROR] Do you already have another mysqld server running on socket: /usr/local/mysql/lib/mysql.sock ?
你没有把原来的那个数据库关掉？就执行更新操作了？

还 ...

老大，我是帮别人看，我对mysql不太会
开始问题好像是硬盘没有空间了
然后被人把数据库移走了，包括错误日志
后来又然装了一个mysql，位置在/use/local/mysql2
现在搞不好了，我接手了

作者: cenalulu 时间: 2009-06-04 15:34
那也就是说你有现成的数据库文件，只是新装了一个mysql？
那么你至少要把my.cnf里的datadir 配置到原来的数据文件夹的位置。

还有就是你新装的mysql版本跟原来一样么？

作者: myr 时间: 2009-06-04 16:17
新装了一个，路径还不一样，版本不知道一样不

作者: Coolriver 时间: 2009-06-04 16:18
LZ估计就是想装一个MySQL在/usr/local/mysql2 下。

你在my.cnf 中声明一下：
[mysqld]
basedir=/usr/local/mysql2
datadir=/usr/local/mysql/var

作者: myr 时间: 2009-06-04 16:31
还是不行

作者: cenalulu 时间: 2009-06-04 17:52
你的mysql数据文件到底存在哪？？
/var/lib/mysql ?
/usr/local/mysql/var ??

作者: myr 时间: 2009-06-04 21:30
老大，我详细的给你说一下整个过程

开始在5月底的时候，数据库出现错误，不可以正常启动（我后来查看错误日志，发现是磁盘空间不够引起的错）
别人把数据库移动到了一个地方（具体哪里我忘记了），这时候数据库还是不可以启动（当然了），
然后就重新安装mysql到/usr/local/mysql2（这时候数据库还没有好，我开始接手），（他不知道那个环节备份过一个my.cnf）

开始的错误提示好像是权限问题
在my.cnf中加入user=mysql，问题解决
然后出现这个错误提示（开始的那个）

我恢复my.cnf文件
把数据库，移回/usr/local/mysql/var
整个过程差不多就这样

/var/lib/mysql下也有文件，文件的日期是6月3日，也就是他安装mysql到/usr/local/mysql2的时候

其实，我的目的很简单，把正在使用的数据库可以正常使用就行了

可以重新安装mysql，然后像sqlserver一样把数据库文件加载上去就可以了

或者像sybase一样，建好库，然后把database文件一替换

首先，如果你决定以后就一直用mysql2的话，最好var文件别放原来的mysql下。

然后你check下面几项吧。
1. ps aux|grep mysql
看看有没有在跑的进程
2. 看一下 /usr/local/mysql2/var 的权限（我的建议是把var放这里或者放/var/lib/mysql 下）
如果你的系统有mysql帐户的话，最好把这个文件夹的owner改成mysql。
3. 把你的my.cnf贴一下
你的有些设置还是跟原来那个数据库有关联，总之很混乱

basedir = /usr/local/mysql2

另外，LZ 以前启动MySQL也是：
#mysqld start
？？？不知道是不是可行？

我的推荐的方法是：
/usr/local/mysql/libexec/mysqld --defaults-file=/etc/my.cnf &
#user = mysql 添加到[mysqld] 中。

其实我比较纠结的是LZ为什么要搞两个mysql。
原来mysql不是能够运行么，只是空间不够，现在够了为什么还要弄个mysql2出来

作者: myr 时间: 2009-06-06 01:54
我也不知道，开始的时候不是我弄得，别人弄不好了，找的我
