Ubuntu 10.10 源碼安裝MySQL 5.1.34

最近將系統(tǒng)重新安裝了Ubuntu 10.10系統(tǒng)，需要重新編譯安裝Mysql，源碼版本是5.1.34

很折騰，不知道10.10的系統(tǒng)改了些什么東西，裝軟件都這么不順利

在這里把發(fā)生的問題都記錄一下:

步驟如下：

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-
 

1. 安裝Ubuntu 10.10下的編譯工具

sudo apt-get install build-essentials

安裝后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時出錯，最后幾行如下：

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

參照 http://bugs.mysql.com/bug.php?id=52514 中對此問題的說明，將Makefile中最后面的do_abi_check注釋掉

跳過ABI Check

重新make成功

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

4. sudo make install 順利通過

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

5. 到目錄/usr/local/mysql下執(zhí)行如下命令 (ice是我的用戶名)

chown -R ice .

chgrp -R ice .

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

6. 到目錄/usr/local/bin 下 運行mysql_install_db --basedir=/usr/local/mysql \

--datadir=/usr/local/mysql/data

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

7. 切到目錄libexec下

-------------------------------------------------------

執(zhí)行命令 ./mysqld 產(chǎn)生如下錯誤

101215 10:09:07 [ERROR] Can't find messagefile '/usr/share/mysql/english/errmsg.sys'

問題的原因,應該是自己沒有定義一個my.cnf配置文件，如果不給自己的配置文件，系統(tǒng)就會用默認的配置，然后就會產(chǎn)生上面的錯誤

將源碼中的 support_files 文件夾下的 my_small.cnf 復制到 /etc/my.cnf下，并增加一個參數(shù)

language = /usr/local/mysql/share/mysql/english

--------------------------------------------------------

運行 ./mysqld 還有錯：

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，查閱官方文檔http://dev.mysql.com/doc/refman/5.1/en/starting-server.html

發(fā)現(xiàn)中間有這么一句話: When the mysqld server starts, it changes location to the data directory.

所以估計上面的錯誤是因為沒有指定datadir參數(shù)，系統(tǒng)默認數(shù)據(jù)文件夾是在 /var/lib/mysql/ 的原故吧

再一次運行命令 ./mysqld --datadir=/usr/local/mysql/data

上面的錯誤沒有了

將這個參數(shù)也加到 /etc/my.cnf 配置文件中

--------------------------------------------------------

運行 ./mysqld 發(fā)生如下錯誤

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

糾結，怎么不斷的有錯誤,繼續(xù)在網(wǎng)上搜索終于找到了問題的根源所在

在Ubuntu下，還有一個這樣的配置文件 /etc/mysql/my.cnf

文件中有下面幾行：

user= mysql

socket= /var/run/mysqld/mysqld.sock

port= 3306

basedir= /usr

datadir= /var/lib/mysql

tmpdir= /tmp

這個配置文件是系統(tǒng)自己帶的，原來上面好多問題都是這個隱藏的配置文件在搞鬼，唉，折騰了好長時間，終于找到問題根源了！

將/etc/mysql/my.cnf 改為 /etc/mysql/my.cnf.backup

再次運行 ./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 終于成功了! 祝賀一下自己！

-----------------------------------------------------------------

注：這兩天又查了一些資料發(fā)現(xiàn)出現(xiàn)這么多問題的原因是由于gcc4.3升級到gcc4.4版本的改動，用gcc4.4編譯，不僅ABI_CHECK出現(xiàn)問題，安裝后執(zhí)行mysql自帶的測試時還有一些測試通不過，將編譯器降為gcc4.3和g++4.3后，源碼安裝過程中就不會出現(xiàn)ABI_CHECK不通過的問題，編譯成功后能通過所有的測試
