Ubuntu 10.10 源码安装MySQL 5.1.34
最近将系统重新安装了Ubuntu 10.10系统，需要重新编译安装Mysql，源码版本是5.1.34很折腾，不知道10.10的系统改了些什么东西，装
最近将系统重新安装了Ubuntu 10.10系统，需要重新编译安装Mysql，源码版本是5.1.34
很折腾，不知道10.10的系统改了些什么东西，装软件都这么不顺利
在这里把发生的问题都记录一下:
步骤如下：
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
1. 安装Ubuntu 10.10下的编译工具
sudo apt-get install build-essentials
安装后gcc 和 g++ 的版本都是 (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
2. ./configure --prefix=/usr/local/mysql
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
3. make
在make时出错，最后几行如下：
make[2]: *** [do_abi_check] Error 1
make[2]: Leaving directory `/home/ice/Documents/software/mysql/src/mysql-5.1.34'
make[1]: *** [abi_check] Error 2
make[1]: Leaving directory `/home/ice/Documents/software/mysql/src/mysql-5.1.34'
make: *** [all-recursive] Error 1
参照 ?id=52514 中对此问题的说明，将Makefile中最后面的do_abi_check注释掉
跳过ABI Check
重新make成功
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
4. sudo make install 顺利通过
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
5. 到目录/usr/local/mysql下执行如下命令 (ice是我的用户名)
chown -R ice .
chgrp -R ice .
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
6. 到目录/usr/local/bin 下 运行mysql_install_db --basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
7. 切到目录libexec下
-------------------------------------------------------
执行命令 ./mysqld 产生如下错误
101215 10:09:07 [ERROR] Can't find messagefile '/usr/share/mysql/english/errmsg.sys'
问题的原因,应该是自己没有定义一个my.cnf配置文件，如果不给自己的配置文件，系统就会用默认的配置，然后就会产生上面的错误
将源码中的 support_files 文件夹下的 my_small.cnf 复制到 /etc/my.cnf下，并增加一个参数
language = /usr/local/mysql/share/mysql/english
--------------------------------------------------------
运行 ./mysqld 还有错：
101215 2:25:47 [Warning] Can't create test file /var/lib/mysql/ice-ThinkPad-R400.lower-test
101215 2:25:47 [Warning] Can't create test file /var/lib/mysql/ice-ThinkPad-R400.lower-test
./mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 2)
101215 2:25:47 [ERROR] Aborting
101215 2:25:47 [Note] ./mysqld: Shutdown complete
未找到原因，查阅官方文档
发现中间有这么一句话: When the mysqld server starts, it changes location to the data directory.
所以估计上面的错误是因为没有指定datadir参数，系统默认数据文件夹是在 /var/lib/mysql/ 的原故吧
再一次运行命令 ./mysqld --datadir=/usr/local/mysql/data
上面的错误没有了
将这个参数也加到 /etc/my.cnf 配置文件中
--------------------------------------------------------
运行 ./mysqld 发生如下错误
101215 11:12:31 [ERROR] Can't start server : Bind on unix socket: No such file or directory
101215 11:12:31 [ERROR] Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?
101215 11:12:31 [ERROR] Aborting
纠结，怎么不断的有错误,继续在网上搜索终于找到了问题的根源所在
在Ubuntu下，还有一个这样的配置文件 /etc/mysql/my.cnf
文件中有下面几行：
user= mysql
socket= /var/run/mysqld/mysqld.sock
port= 3306
basedir= /usr
datadir= /var/lib/mysql
tmpdir= /tmp
这个配置文件是系统自己带的，原来上面好多问题都是这个隐藏的配置文件在搞鬼，唉，折腾了好长时间，终于找到问题根源了！
将/etc/mysql/my.cnf 改为 /etc/mysql/my.cnf.backup
再次运行 ./mysqld
101215 11:54:11 [Note] Event Scheduler: Loaded 0 events
101215 11:54:11 [Note] ./mysqld: ready for connections.
Version: '5.1.34' socket: '/tmp/mysql.sock' port: 3306 Source distribution
ready for connections 终于成功了! 祝贺一下自己！
-----------------------------------------------------------------
注：这两天又查了一些资料发现出现这么多问题的原因是由于gcc4.3升级到gcc4.4版本的改动，，用gcc4.4编译，不仅ABI_CHECK出现问题，安装后执行mysql自带的测试时还有一些测试通不过，将编译器降为gcc4.3和g++4.3后，源码安装过程中就不会出现ABI_CHECK不通过的问题，编译成功后能通过所有的测试
