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.gz
Mysql 下载地址：http://dev.mysql.com/downloads/
2. Cmake安装包
mysql5.5以后是通过cmake来编译的
wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz
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
[[email protected] /]# rpm -qa | grep -i mysql
mysql-libs-5.1.52-1.el6_0.1.i686
qt-mysql-4.6.2-20.el6.i686
mysql-server-5.1.52-1.el6_0.1.i686
mysql-5.1.52-1.el6_0.1.i686
perl-DBD-MySQL-4.013-3.el6.i686
3.2 使用yum来删除MySQL
[[email protected] ~]# yum -y remove mysql-server-5.1.52-1.el6_0.1.i686
[[email protected] ~]# yum -y remove mysql-5.1.52-1.el6_0.1.i686
[[email protected] ~]# yum -y remove mysql-libs-5.1.52-1.el6_0.1.i686
4 主服务器上安装MySql
4.1 先安装cmake
[[email protected] software]# tar -zxvf cmake-2.8.4.tar.gz
[[email protected] software]# cd cmake-2.8.4
[[email protected] cmake-2.8.4]# ./configure
[[email protected] cmake-2.8.4]# make
[[email protected] cmake-2.8.4]# make install
4.2 创建mysql的安装目录及数据存放目录
[[email protected] opt]# mkdir /opt/mysql //安装mysql
[[email protected] opt]# mkdir /opt/mysql/data //存放数据
4.3 创建mysql用户及用户组
[[email protected] opt]# groupadd mysql
[[email protected] 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
[[email protected] software]# tar -zxvf mysql-5.6.15.tar.gz
[[email protected] software]# cd mysql-5.6.15
[[email protected] mysql-5.6.15]# cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql \
-DSYSCONFDIR=/opt/mysql/etc \
-DMYSQL_DATADIR=/opt/mysql/data \

-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

参数详细见：http://dev.mysql.com/doc/refman/5.6/en/source-configuration-options.html
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

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 is
strongly 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!
The latest information about MySQL is available on the web at
Support MySQL by buying support/licenses at http://shop.mysql.com
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
[[email protected] mysql]# chown -R root .
[[email protected] mysql]# chown -R mysql data
[[email protected] mysql]# bin/mysqld_safe --user=mysql &
[3] 20646
[[email protected] 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/data
4.6 配置数据库
修改密码：
[[email protected] mysql]# bin/mysqladmin -u root password ‘mysql‘
[[email protected] mysql]# cp support-files/mysql.server /etc/init.d/
[[email protected] 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：
[[email protected] etc]# cd /etc
[[email protected] etc]# vi profile
在文件最后增加：
PATH=/opt/mysql/bin:/opt/mysql/lib:$PATH
export PATH
4.7 手工启动数据库
[[email protected] mysql]# service mysql.server status

[[email protected] mysql]# service mysql.server start
