centos编译安装mysql5.5

centos编译安装mysql5.5

 

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  www.2cto.com  

 

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  --------------------------------------------- CMake 2.8.4, Copyright 2000-2009 Kitware, Inc. --------------------------------------------- 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.  --------------------------------------------- Log of errors: /usr/local/src/cmake-2.8.4/Bootstrap.cmk/cmake_bootstrap.log ---------------------------------------------

报错：缺少C的编译器。  www.2cto.com  

 

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. C compiler on this system is: cc  --------------------------------------------- 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. --------------------------------------------- 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  www.2cto.com  

 

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：  www.2cto.com  

 

-- 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!
 

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 .

  www.2cto.com  

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  www.2cto.com  

 

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 &

 

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：

  www.2cto.com  

使用SET PASSWORD语句

 

[root@localhost ~]# mysql -u root

mysql> SET PASSWORD FOR &＃39;root&＃39;@&＃39;localhost&＃39; = PASSWORD(&＃39;newpwd&＃39;); mysql> SET PASSWORD FOR &＃39;root&＃39;@&＃39;host_name&＃39; = PASSWORD(&＃39;newpwd&＃39;)

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(&＃39;newpwd&＃39;)     ->     WHERE User = &＃39;root&＃39;; 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  www.2cto.com  

 

[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
