推薦:/var/log/pacct文件導(dǎo)致MySQL啟動(dòng)失敗的案例分享
毫無預(yù)兆的,MySQL 罷工了。 用 mysql.server 啟動(dòng)腳本啟動(dòng)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(yùn)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(gè)。

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(huì)報(bào)這個(gè)錯(cuò),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(dòng)mysql

 

代碼如下:
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql  

 

這里可能會(huì)發(fā)生錯(cuò)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(dòng)mysql

 

代碼如下:
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql

 

注冊(cè)mysql服務(wù),開機(jī)自動(dòng)啟動(dòng)

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(dòng)mysql服務(wù)

 

代碼如下:
[root@local ~]# service mysql start  

 

測(cè)試mysql是否安裝成功

 

代碼如下:
[root@local ~]# /usr/local/mysql/bin/mysql -u root -p

分享:MySQL中在查詢結(jié)果集中得到記錄行號(hào)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(gè)結(jié)果集中的行號(hào), 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
