这里有新鲜出炉的Mysql教程,程序狗速度看过来!

Mysql关系型数据库管理系统

MySQL是一个开放源码的小型关联式数据库管理系统,开发者为瑞典MySQL AB公司。MySQL被广泛地应用在Internet上的中小型网站中。由于其体积小、速度快、总体拥有成本低,尤其是开放源码这一特点,许多中小型网站为了降低网站总体拥有成本而选择了MySQL作为网站数据库。


这篇文章主要介绍了Centos5.5中安装Mysql5.5过程分享,本文使用编译方法安装MySQL,并给出了一些可能遇到的错误和解决方法,需要的朋友可以参考下

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



[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



[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



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



[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



[root@local mysql-5.5.37]# rm -f CMakeCache.txt

继续编译mysql



[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



[root@local ~]# groupadd mysql

[root@local ~]# useradd –r –g mysql mysql

[root@local ~]# chown –R mysql.mysql /usr/local/mysql

启动mysql



[root@local ~]# /usr/local/mysql/bin/mysqld_safe --user=mysql  

这里可能会发生错误,没有就跳过:



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:



[root@local ~]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

再启动mysql



[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



[root@local ~]# cp /usr/local/mysql/support-files/my-medium.cnf/etc/my.cnf  

2.设置mysql开机自启



[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



[root@local ~]# service mysql start  

测试mysql是否安装成功



[root@local ~]# /usr/local/mysql/bin/mysql -u root -p  

Enter password:
