安装Mysql5.5之前先卸载CentOS自带的Mysql5.0。
- [root@localhost ~]# yum remove mysql
编译安装cmake
下载cmake源码包cmake-2.8.4.tar.gz,mv到/usr/local/src目录下
- [root@localhost ~]# cd /usr/local/src/
- [root@localhost src]# tar xzvf cmake-2.8.4.tar.gz
- [root@localhost src]# cd cmake-2.8.4
- [root@localhost cmake-2.8.4]# ./bootstrap
- ---------------------------------------------

报错:缺少C的编译器。
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-2.8.4]# ./bootstrap
- ---------------------------------------------
- CMake 2.8.4, Copyright 2000-2009 Kitware, Inc.

- ---------------------------------------------
- Log of errors: /usr/local/src/cmake-2.8.4/Bootstrap.cmk/cmake_bootstrap.log
- ---------------------------------------------
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-2.8.4]# ./bootstrap
没有报错后,编译安装
- [root@localhost cmake-2.8.4]# gmake
- [root@localhost cmake-2.8.4]# gmake install
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-5.5.11.tar.gz到/usr/local/src下,解压
- [root@localhost ~]# cd /usr/local/src/
- [root@localhost src]# tar xzvf mysql-5.5.11.tar.gz
- [root@localhost src]# cd mysql-5.5.11
cmake运行
- [root@localhost mysql-5.5.11]# 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)

-
- -- Configuring incomplete, errors occurred!
缺少Curses包,解决办法:
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev,
on Redhat and derivates it is ncurses-devel.很容易看懂,不解释了...
在CentOS下需要安装ncurses-devel
- [root@localhost mysql-5.5.11]# yum install ncurses-devel
重新cmake运行
- [root@localhost mysql-5.5.11]# 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-5.5.11]# yum install bison
再次运行,没有报错
- [root@localhost mysql-5.5.11]# cmake .
在编译安装前,可以设置安装的配置选项
- [root@localhost mysql-5.5.11]# ./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,可以泡杯咖啡转悠一下...
- [root@localhost mysql-5.5.11]# 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,数据目录的说有权改为mysql用户,更新授权表
- [root@localhost mysql-5.5.11]# 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
安全启动mysql
- [root@localhost mysql]# ./bin/mysqld_safe --user=mysql &"white-space: normal;">
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
有3种方法为root账户设置密码:
使用SET PASSWORD语句
- [root@localhost ~]# mysql -u root
- mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');
- mysql> SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd')
使用mysqladmin命令行程序
- [root@localhost ~]# mysqladmin -u root password "newpwd"
- [root@localhost ~]# mysqladmin -u root -h host_name password "newpwd"
使用UPDATE语句
- [root@localhost ~]# mysql -u root
- mysql> UPDATE mysql.user SET Password = PASSWORD('newpwd')
- -> WHERE User = 'root';
- mysql> FLUSH PRIVILEGES;
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
现在可以通过服务来启动和关闭Mysql
- [root@localhost ~]# service mysql start
- [root@localhost ~]# service mysql shutdown
基本上的安装就是这样了......
