CentOS 6.5系统安装配置MySQL 5.6数据库

发布时间:2014-03-30 来源:服务器之家

先卸载CentOS自带的Mysql

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

 yum install cmake

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/usr/local/src下,解压

[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# tar xzvf mysql-5.6.15.tar.gz
 [root@localhost src]# cd mysql-5.6.15

cmake运行

[root@localhost mysql-5.6.15]# cmake .

-- 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.

[root@localhost mysql-5.6.15]# yum install ncurses-devel

重新cmake运行

[root@localhost mysql-5.6.15]# cmake . -DENABLE_DOWNLOADS=1

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-5.6.15]# yum install bison

再次运行,没有报错

[root@localhost mysql-5.6.15]# cmake . -DENABLE_DOWNLOADS=1

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-5.6.15]# make && make install

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-5.6.15]# 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:

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 my.cnf  /etc/mysql.cnf

 如果

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
