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 -pyourpasswordWelcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 3 to server version: 5.5.27 Source distributinoType '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
