      毫無預(yù)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(jié)束,mysqld進(jìn)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(jié)果發(fā)現(xiàn)

      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(yīng)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(tǒng)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(jìn)行下一步

       

      代碼如下:
      [root@local mysql-5.5.37]# rm -f CMakeCache.txt

       

      繼續(xù)編譯mysql

       

      代碼如下:
      [root@local ~]# cmake ./
      [root@local ~]# make
      [root@local ~]# make install

       

      這樣,mysql默認(rèn)將成功安裝到/usr/local/mysql

      創(chuàng)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(fā)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(wù),開機(jī)自動啟動

      1.設(shè)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(shè)置mysql開機(jī)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(wù)

       

      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(jié)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(jié)果集中的行號, ISO SQL:2003 標(biāo)準(zhǔn)提出的方法是提供 ROW_NUMBER() / RANK() 函數(shù)。 Oracle 中可以使用標(biāo)準(zhǔn)方法(8i版本以上),也可以使用非標(biāo)準(zhǔn)的 ROWNUM ; MS SQL Server 則在 2005 版本中提供了 ROW_NUMB
