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.

#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.
