解压下载的安装包:
安装mysql:
#chmod +x configure.sh
#./configure.sh
#make && make install
#groupadd mysql /添加一个mysql组
#useradd -g mysql mysql 添加一个mysql用户到mysql组里
#cp support-files/my-medium.cnf /etc/my.cnf
#cp support-files/mysql.server /etc/rc.d/init.d/mysqld
#chmod 700 /etc/init.d/mysqld
#chkconfig --add mysqld
#chkconfig --level 345 mysqld on
#cd /usr/local/mysql
#bin/mysql_install_db --user=mysql
#chown -R root .
#chown -R mysql var
#chgrp -R mysql .
#bin/mysqld_safe --user=mysql &
#bin/mysqladmin -uroot -poldpwd password XXXX
下面介绍下 mysql 多实例安装的方法。

注意:如果编译出现问题,请安装ncurses-devel-5.5-24.20060715.x86_64.rpm。
一般即可解决问题。
开始安装:
#chmod +x configure.sh
#./configure.sh
#make && make install
创建mysql用户:
#groupadd mysql
#useradd -g mysql mysql
#cp support-files/my-medium.cnf /etc/my.cnf
#cp support-files/mysql.server /etc/rc.d/init.d/mysqld
#cp support-files/mysqld_multi.server /etc/rc.d/init.d/mysqld_multi
#chmod 700 /etc/init.d/mysqld
(忽略该步)#chkconfig --add mysqld
(忽略该步)#chkconfig --level 2345 mysqld off
#cd /usr/local/mysql
show variables like 'server_id';
查看server-id
手动修改server-id
6)change master之后,查看slave的状态,发现slave_IO_running 为NO
注意:做完上述操作之后,记得重启mysql进程:
(初始化数据目录)
#bin/mysql_install_db --user=mysql --datadir=/usr/local/mysql/var21001/
#bin/mysql_install_db --user=mysql --datadir=/usr/local/mysql/var21002/
#bin/mysql_install_db --user=mysql --datadir=/usr/local/mysql/var21003/
#bin/mysql_install_db --user=mysql --datadir=/usr/local/mysql/var(默认)
#chown -R root .
#chown -R mysql var21001/ var21002/ var21003/
#chgrp -R mysql .
#bin/mysqld_safe --user=mysql &
(到此安装完成)
#bin/mysqladmin -uroot -poldpwd password 1qaz@WSX

flush privileges;
//set password for root@'localhost' =password('XXX');
//set password for root@'127.0.0.1' =password('XXX');
