MySql主从安装

1 环境介绍

操作系统：Oracle Linux Server release 6.2

2 安装软件采用源码安装方式1. mysql安装包：mysql-5.6.15.tar.gzMysql 下载地址：2.  Cmake安装包mysql5.5以后是通过cmake来编译的wget 

3 删除Oracle Linux自带的MySql

如果已经安装了Mysql其他版本，先删除3.1 检查是否安装了MySQL[root@study1 /]# rpm -qa | grep -i mysqlmysql-libs-5.1.52-1.el6_0.1.i686qt-mysql-4.6.2-20.el6.i686mysql-server-5.1.52-1.el6_0.1.i686mysql-5.1.52-1.el6_0.1.i686perl-DBD-MySQL-4.013-3.el6.i686

3.2 使用yum来删除MySQL

[root@study1 ~]# yum -y remove  mysql-server-5.1.52-1.el6_0.1.i686[root@study1 ~]# yum -y remove mysql-5.1.52-1.el6_0.1.i686[root@study1 ~]# yum -y remove mysql-libs-5.1.52-1.el6_0.1.i6864 主服务器上安装MySql4.1 先安装cmake[root@study1 software]# tar -zxvf cmake-2.8.4.tar.gz[root@study1 software]# cd cmake-2.8.4[root@study1 cmake-2.8.4]# ./configure[root@study1 cmake-2.8.4]# make[root@study1 cmake-2.8.4]# make install

4.2 创建mysql的安装目录及数据存放目录

[root@study1 opt]# mkdir /opt/mysql        //安装mysql[root@study1 opt]# mkdir /opt/mysql/data    //存放数据4.3 创建mysql用户及用户组[root@study1 opt]# groupadd mysql[root@study1 opt]# useradd –r –g mysql mysql赋予数据存放目录权限：chown mysql:mysql -R /opt/mysql/data

4.4 编译安装mysql

? 编译[root@study1 software]# tar -zxvf mysql-5.6.15.tar.gz[root@study1 software]# cd mysql-5.6.15[root@study1 mysql-5.6.15]# cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql \ -DSYSCONFDIR=/opt/mysql/etc \ -DMYSQL_DATADIR=/opt/mysql/data \ -DMYSQL_TCP_PORT=3306 \ -DMYSQL_UNIX_ADDR=/tmp/mysqld.sock \ -DWITH_EXTRA_CHARSETS=all \ -DWITH_SSL=bundled \ -DWITH_EMBEDDED_SERVER=1 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci

参数说明：

 CMAKE_INSTALL_PREFIX ： MySQL安装目录 SYSCONFDIR ： 配置文件目录 MYSQL_DATADIR :数据库目录 MYSQL_TCP_PORT ：数据库端口 MYSQL_UNIX_ADDR ：安排个目录放mysql.sock文件把，可以设置为日志存放，data存放目录等位置 WITH_EXTRA_CHARSETS : 字符 WITH_SSL       ：the type of SSL WITH_EMBEDDED_SERVER ：Whether to build embedded server (默认：OFF) ENABLED_LOCAL_INFILE ：Whether to enable LOCAL for LOAD DATA INFILE（默认:OFF）  允许从本地导入数据 WITH_INNOBASE_STORAGE_ENGINE:  1

参数详细见：

如果发生错误查看：。。。/mysql-5.6.15/CMakeFiles下的CMakeError.log、CMakeOutput.log文件注意事项：重新编译时，需要清除旧的对象文件和缓存信息。# rm -f CMakeCache.txt? 安装[root@study1 mysql-5.6.15]# make[root@study1 mysql-5.6.15]# make install

4.5 初始化数据库

[root@study1 mysql]# cd /opt/mysql[root@study1 mysql]# mkdir etc[root@study1 mysql]# mkdir log[root@study1 mysql]#  chown -R mysql .[root@study1 mysql]# chgrp -R mysql .[root@study1 mysql]# scripts/mysql_install_db --user=mysql --basedir=/opt/mysql/ --datadir=/opt/mysql/data/Installing MySQL system tables...2014-01-23 10:18:50 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

  /opt/mysql//bin/mysqladmin -u root password 'new-password'

  /opt/mysql//bin/mysqladmin -u root -h study1.dlt password 'new-password'

Alternatively you can run:

  /opt/mysql//bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default.  This isstrongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

  cd . ; /opt/mysql//bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

  cd mysql-test ; perl mysql-test-run.pl

Please report any problems with the ./bin/mysqlbug script!

Support MySQL by buying support/licenses at 

New default config file was created as /opt/mysql//my.cnf and

will be used by default by the server when you start it.You may edit this file to change server settings

[root@study1 mysql]# chown -R root .[root@study1 mysql]# chown -R mysql data[root@study1 mysql]#  bin/mysqld_safe --user=mysql &[3] 20646[root@study1 mysql]# 140123 10:42:05 mysqld_safe Logging to '/opt/mysql/data/study1.dlt.err'.140123 10:42:05 mysqld_safe Starting mysqld daemon with databases from /opt/mysql/data4.6 配置数据库    修改密码：[root@study1 mysql]# bin/mysqladmin -u root password 'mysql'

[root@study1 mysql]# cp support-files/mysql.server /etc/init.d/[root@study1 mysql]# cp support-files/my-default.cnf  etc/my.cnf

编辑etc/my.cnf,zai [mysqld]下增加lower_case_table_names=1

设置环境：[root@study1 etc]# cd /etc[root@study1 etc]# vi profile在文件最后增加：PATH=/opt/mysql/bin:/opt/mysql/lib:$PATHexport PATH
