Centos5.5中安装Mysql5.5过程分享_MySQL教程
推荐:/var/log/pacct文件导致MySQL启动失败的案例分享毫无预兆的,MySQL 罢工了。 用 mysql.server 启动脚本启动之后,没有任何提示信息就结束,mysqld进程自然是没有起来。 把 mysql.server 里面 $bindir/mysqld_safe --datadir=$datadir --pid-file=$server_pid_file /dev/null 21 这句的输出重定向去掉后运行,结果发现
这几天在centos下装mysql,这里记录一下安装的过程,方便以后查阅
Mysql5.5.37安装需要cmake,5.6版本开始都需要cmake来编译,5.5以后的版本应该也要装这个。
安装cmake
代码如下:
[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
安装mysql
代码如下:
[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 ./
可能还会报这个错,没有就跳过
代码如下:
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".
说明centos系统没有ncurses-devel
代码如下:
[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
再删除刚才编译生成的 CMakeCache.txt 文件,否则无法进行下一步
代码如下:
[root@local mysql-5.5.37]# rm -f CMakeCache.txt
继续编译mysql
代码如下:
[root@local ~]# cmake ./
[root@local ~]# make
[root@local ~]# make install
这样,mysql默认将成功安装到/usr/local/mysql
创建mysql用户组
代码如下:
[root@local ~]# groupadd mysql
[root@local ~]# useradd –r –g mysql mysql
[root@local ~]# chown –R mysql.mysql /usr/local/mysql
启动mysql
代码如下:
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql
这里可能会发生错误,没有就跳过:
代码如下:
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.
解决方法:
代码如下:
[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
再启动mysql
代码如下:
[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql
注册mysql服务,开机自动启动
1.设置mysql配置文件到/etc目录
代码如下:
[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf
2.设置mysql开机自启
代码如下:
[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.启动mysql服务
代码如下:
[root@local ~]# service mysql start
测试mysql是否安装成功
代码如下:
[root@local ~]# /usr/local/mysql/bin/mysql -u root -p
Enter password:

分享:MySQL中在查询结果集中得到记录行号的方法如果需要在查询语句返回的列中包含一列表示该条记录在整个结果集中的行号, ISO SQL:2003 标准提出的方法是提供 ROW_NUMBER() / RANK() 函数。 Oracle 中可以使用标准方法(8i版本以上),也可以使用非标准的 ROWNUM ; MS SQL Server 则在 2005 版本中提供了 ROW_NUMB
