Centos5.5中安裝Mysql5.5過程分享_MySQL教程
推薦:/var/log/pacct文件導致MySQL啟動失敗的案例分享毫無預兆的,MySQL 罷工了。 用 mysql.server 啟動腳本啟動之后,沒有任何提示信息就結束,mysqld進程自然是沒有起來。 把 mysql.server 里面 $bindir/mysqld_safe --datadir=$datadir --pid-file=$server_pid_file /dev/null 21 這句的輸出重定向去掉后運行,結果發現
這幾天在centos下裝mysql,這里記錄一下安裝的過程,方便以后查閱
Mysql5.5.37安裝需要cmake,5.6版本開始都需要cmake來編譯,5.5以后的版本應該也要裝這個。
安裝cmake
代碼如下:
[root@local ~]# wget http://www.cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz
[root@local ~]# tar xvf cmake-2.8.12.2.tar.gz
[root@local ~]# cd cmake-2.8.12.2
[root@local cmake-2.8.12.2]#./bootstrap
[root@local cmake-2.8.12.2]# make
[root@local cmake-2.8.12.2]# make install
安裝mysql
代碼如下:
[root@local ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.37.tar.gz
[root@local ~]# tar xvf mysql-5.5.37.tar.gz
[root@local ~]# cd mysql-5.5.37
[root@local mysql-5.5.37]# cmake ./
可能還會報這個錯,沒有就跳過
代碼如下:
CMake Error at cmake/readline.cmake:83(MESSAGE):
Curses library not found. Pleaseinstall appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name islibncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake:127 (FIND_CURSES)
cmake/readline.cmake:217 (MYSQL_USE_BUNDLED_LIBEDIT)
CMakeLists.txt:355 (MYSQL_CHECK_READLINE
-- Configuring incomplete, errors occurred!
See also "/root/my/mysql-5.5.37/CMakeFiles/CMakeOutput.log".
See also"/root/my/mysql-5.5.37/CMakeFiles/CMakeError.log".
說明centos系統沒有ncurses-devel
代碼如下:
[root@local ~]# wget http://invisible-island.net/datafiles/release/ncurses.tar.gz
[root@local ~]# cd ncurses-5.9
[root@local ncurses-5.9]#./configure
[root@local ncurses-5.9]# make
[root@local ncurses-5.9]# make install
再刪除剛才編譯生成的 CMakeCache.txt 文件,否則無法進行下一步
代碼如下:
[root@local mysql-5.5.37]# rm -f CMakeCache.txt
繼續編譯mysql
代碼如下:
[root@local ~]# cmake ./
[root@local ~]# make
[root@local ~]# make install
這樣,mysql默認將成功安裝到/usr/local/mysql
創建mysql用戶組
代碼如下:
[root@local ~]# groupadd mysql
[root@local ~]# useradd –r –g mysql mysql
[root@local ~]# chown –R mysql.mysql /usr/local/mysql
啟動mysql
代碼如下:
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql
這里可能會發生錯誤,沒有就跳過:
代碼如下:
FATAL ERROR: Could not find./bin/my_print_defaults
If you compiled from source, you need torun 'make install' to
copy the software into the correct locationready for operation.
If you are using a binary release, you musteither be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
解決方法:
代碼如下:
[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
再啟動mysql
代碼如下:
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql
注冊mysql服務,開機自動啟動
1.設置mysql配置文件到/etc目錄
代碼如下:
[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf
2.設置mysql開機自啟
代碼如下:
[root@local ~]# cp/usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@local ~]# chmod +x /etc/init.d/mysql
[root@local ~]# /sbin/chkconfig --add mysql
3.啟動mysql服務
代碼如下:
[root@local ~]# service mysql start
測試mysql是否安裝成功
代碼如下:
[root@local ~]# /usr/local/mysql/bin/mysql -u root -p
Enter password:

分享:MySQL中在查詢結果集中得到記錄行號的方法如果需要在查詢語句返回的列中包含一列表示該條記錄在整個結果集中的行號, ISO SQL:2003 標準提出的方法是提供 ROW_NUMBER() / RANK() 函數。 Oracle 中可以使用標準方法(8i版本以上),也可以使用非標準的 ROWNUM ; MS SQL Server 則在 2005 版本中提供了 ROW_NUMB
