关系型系统之Mysql安装配置教程
MySQL，目前在中小企业大受欢迎，其成本低廉，而且所使用的编程语言都是简单易懂，稍稍懂得mysql原理的同学都可以进行简单的编程。
MySQL是最流行的关系型数据库管理系统，由瑞典MySQLAB公司开发，目前属于Oracle公司。
MySQL所使用的SQL语言是用于访问数据库的最常用标准化语言。
MySQL由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点，一般中小型网站的开发都选择MySQL作为网站数据库。
MySQL安装
本教程的系统平台：CentOSrelease6.6(Final)64位。
一、安装编译工具及库文件
yum-yinstallgccgcc-c++makeautoconflibtool-ltdl-develgd-develfreetype-devellibxml2-devellibjpeg-devellibpng-developenssl-develcurl-develbisonpatchunziplibmcrypt-devellibmhash-develncurses-develsudobzip2flexlibaio-devel
二、安装cmake编译器
cmake版本：cmake-3.1.1。
1、下载地址：http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz
[[email protected],ccsrc]#wgethttp://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz
2、解压安装包
[[email protected],ccsrc]#tarzxvfcmake-3.1.1.tar.gz
3、进入安装包目录
[[email protected],ccsrc]#cdcmake-3.1.1
4、编译安装
[[email protected],cccmake-3.1.1]#./bootstrap[[email protected],cccmake-3.1.1]#make&&makeinstall
三、安装MySQL
MySQL版本：mysql-5.6.15。
1、下载地址：http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz
[[email protected],ccsrc]#wgethttp://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz
2、解压安装包
[[email protected],ccsrc]#tarzxvfmysql-5.6.15.tar.gz
3、进入安装包目录
[[email protected],ccsrc]#cdmysql-5.6.15
4、编译安装
[[email protected],ccmysql-5.6.15]#cmake-DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/-DMYSQL_UNIX_ADDR=/tmp/mysql.sock-DDEFAULT_CHARSET=utf8-DDEFAULT_COLLATION=utf8_general_ci-DWITH_EXTRA_CHARSETS=all-DWITH_MYISAM_STORAGE_ENGINE=1-DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_MEMORY_STORAGE_ENGINE=1-DWITH_READLINE=1-DWITH_INNODB_MEMCACHED=1-DWITH_DEBUG=OFF-DWITH_ZLIB=bundled-DENABLED_LOCAL_INFILE=1-DENABLED_PROFILING=ON-DMYSQL_MAINTAINER_MODE=OFF-DMYSQL_DATADIR=/usr/local/webserver/mysql/data-DMYSQL_TCP_PORT=3306[[email protected],ccmysql-5.6.15]#make&&makeinstall
5、查看mysql版本:
[[email protected],ccmysql-5.6.15]#/usr/local/webserver/mysql/bin/mysql–version
到此，mysql安装完成。
MySQL配置
1、创建mysql运行使用的用户mysql：
[[email protected]]#/usr/sbin/groupaddmysql[[email protected]]#/usr/sbin/useradd-gmysqlmysql
2、创建binlog和库的存储路径并赋予mysql用户权限
[[email protected],ccmysql]#mkdir-p/usr/local/webserver/mysql/binlog/www/data_mysql[[email protected],ccmysql]#chownmysql.mysql/usr/local/webserver/mysql/binlog//www/data_mysql/
2、创建my.cnf配置文件
将/etc/my.cnf替换为下面内容
[[email protected],ccmysql]#cat/etc/my.cnf[client]port=3306socket=/tmp/mysql.sock[mysqld]replicate-ignore-db=mysql
replicate-ignore-db=test
replicate-ignore-db=information_schema

3、初始化数据库
[[email protected],ccmysql]#/usr/local/webserver/mysql/scripts/mysql_install_db–defaults-file=/etc/my.cnf–user=mysql
显示如下信息：
InstallingMySQLsystemtables…2015-01-2620:18:510[Warning]TIMESTAMPwithimplicitDEFAULTvalueisdeprecated.Pleaseuse–explicit_defaults_for_timestampserveroption(seedocumentationformoredetails).OKFillinghelptables…2015-01-2620:18:570[Warning]TIMESTAMPwithimplicitDEFAULTvalueisdeprecated.Pleaseuse–explicit_defaults_for_timestampserveroption(seedocumentationformoredetails).OK…
4、创建开机启动脚本
[[email protected],ccmysql]#cd/usr/local/webserver/mysql/[[email protected],ccmysql]#cpsupport-files/mysql.server/etc/rc.d/init.d/mysqld
[[email protected],ccmysql]#chkconfig–addmysqld
[[email protected],ccmysql]#chkconfig–level35mysqldon
4、启动mysql服务器
[[email protected],ccmysql]#servicemysqldstart
5、连接MySQL
[[email protected],ccmysql]#/usr/local/webserver/mysql/bin/mysql-uroot-p
修改MySQL用户密码
mysqladmin-u用户名-p旧密码password新密码
或进入mysql命令行
SETPASSWORDFOR'用户名'@'主机'=PASSWORD(‘密码');
创建新用户并授权:
grantallprivilegeson*.*to用户名@'%'identifiedby'密码'withgrantoption;
其他命令
启动：servicemysqldstart
停止：servicemysqldstop
重启：servicemysqldrestart
重载配置：servicemysqldreload
