网络上有很多相关的安装笔记,但是并不详尽,或是编译环境稍有不同,过程就会有差异,所以我总结了已有的经验和我自己安装过程中的体验,扩充并详尽地记录了整个过程。我选择安装的是MySQL5.5.27版本。以下是我的安装笔记。

打开终端

切换到根目录

[shell@localhost ~]# su -

安装Mysql5.5之前先卸载CentOS自带的Mysql5.0。

[root@localhost ~]# yum remove mysql

安装cmake

下载cmake源码包cmake-2.8.5.tar.gz

[root@localhost ~]# wget http://www.cmake.org/files/v2.8/cmake-2.8.5.tar.gz
编译安装
[root@localhost]# tar xzvf cmake-2.8.5.tar.gz  
[root@localhost]# cd cmake-2.8.5 
[root@localhost cmake-2.8.5]# ./bootstrap  
 
Error when bootstrapping CMake: Cannot find appropriate C compiler on this system. Please specify one using environment variable CC. See cmake_bootstrap.log for compilers attempted. 
 

报错:缺少C的编译器。

解决方法:安装gcc编译器

可以从Linux系统的安装盘中安装,也可以简单地用yum安装

[root@localhost ~]# yum install gcc

继续cmake的安装

[root@localhost cmake-2.8.5]# ./bootstrap  
Error when bootstrapping CMake: Cannot find appropriate C++ compiler on this system. Please specify one using environment variable CXX. See cmake_bootstrap.log for compilers attempted.
 

再次报错:缺少C++编译器。

安装gcc-c++编译器

同样可以从Linux系统的安装盘中安装,或者简单地用yum安装

[root@localhost ~]# yum install gcc-c++

重复上面的操作

[root@localhost cmake-2.8.5]# ./bootstrap 

没有报错后,编译安装

[root@localhost cmake-2.8.5]# make 
[root@localhost cmake-2.8.5]# make install
[root@localhost cmake-2.8.5]# cmake -version

开始正式安装Mysql

添加mysql用户和用户组

[root@localhost ~]# groupadd mysql 
[root@localhost ~]# useradd -g mysql mysql

下载mysql的源码包mysql-5.5.27.tar.gz

[root@localhost ~]# wget http://dev.mysql.com/Downloads/MySQL-5.5/mysql-5.5.27.tar.gz

解压

[root@localhost ~]# cd /usr/local/
[root@localhost local]# tar xzvf mysql-5.5.27.tar.gz
[root@localhost local]# cd mysql-5.5.27

cmake运行

[root@localhost mysql-5.5.27]# cmake .

报错:

-- Could NOT find Curses (missing:  CURSES_LIBRARY CURSES_INCLUDE_PATH)  CMake Error at cmake/readline.cmake:82 (MESSAGE):   Curses library not found.  Please install appropriate package,        remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel. Call Stack (most recent call first):   cmake/readline.cmake:126 (FIND_CURSES)   cmake/readline.cmake:216 (MYSQL_USE_BUNDLED_LIBEDIT)   CMakeLists.txt:250 (MYSQL_CHECK_READLINE)  -- Configuring incomplete, errors occurred!

解决办法:

[root@localhost mysql-5.5.27]# rm CMakeCache.txt 
[root@localhost mysql-5.5.27]# yum -y install ncurses-devel*

重新cmake运行

[root@localhost mysql-5.5.27]# cmake .

还是有个警告

Warning: Bison executable not found in PATH

有一个警告,也解决了它,缺少Bison就安装一下

[root@localhost mysql-5.5.27]# yum install bison

再次运行,没有报错

[root@localhost mysql-5.5.27]# cmake .

在编译安装前,可以设置安装的配置选项

[root@localhost mysql-5.5.27]# ./configure --help

根据帮助信息选择自己需要设置的选项,当然也可以跳过这步,按默认设置

#开始编译安装,时间有点稍长...

[root@localhost mysql-5.5.27]# make && make install

完成编译安装

进入安装目录,将程序二进制的所有权改为root,数据目录的所有权改为mysql用户,更新授权表

[root@localhost mysql-5.5.27]# cd /usr/local/mysql
[root@localhost mysql]# chown -R root . 
[root@localhost mysql]# chown -R mysql . 
[root@localhost mysql]# chgrp -R mysql . 
[root@localhost mysql]# scripts/mysql_install_db --user=mysql
 
初始化数据库
[root@localhost mysql]# /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
 

安全启动mysql

[root@localhost mysql]# ./bin/mysqld_safe --user=mysql

关闭mysql

[root@localhost mysql]# ./bin/mysqladmin -u root shutdown -p
默认密码为空
方便调用,为mysql设置一个软链接
[root@localhost ~]# ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql

其他设置处理:

设置选项文件,将配置文件拷贝到/etc下

[root@localhost mysql]# cp support-files/my-medium.cnf /etc/mysql.cnf
 
设置开机自启动
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysql 
[root@localhost mysql]# chmod +x /etc/init.d/mysql 
[root@localhost mysql]# chkconfig –add mysqld
[root@localhost mysql]# chkconfg mysqld on

现在可以通过服务来启动和关闭Mysql服务器

[root@localhost ~]# service mysql start 
[root@localhost ~]# service mysql shutdown

连接服务器

[root@localhost ~]# ./mysql -u root -p yourpassword
Welcome to the MySQL monitor.  Commands end with ; or /g.

Type 'help;' or '/h' for help. Type '/c' to clear the buffer.
mysql> ...

mysql> 提示符告诉你mysql准备为你输入命令。

至此MySQL已经正常安装并可以使用
