主从mysql架设

二进制安装mysql

tar xvf mysql-5.1.46-linux-i686-glibc23.tar -C /usr/local

cd /usr/local

ln -sv mysql-5.1.46-linux-i686-glibc23.tar mysql

cd mysql

groupadd mysql

useradd -g mysql -s /sbin/nologin -M -r mysql

mkdir /mysql/data

chown -R mysql.mysql /mysql/data

-r :加一系统用户

cd /usr/local/mysql

chown mysql:mysql . -R

#use mysql to init

scripts/mysql_install_db --user=mysql --datadir=/var/mysql/data

chown root . -R

chown mysql data/ -R

cp support-files/my-large.cnf /etc/my.cnf

################################

vim /etc/my.cnf

datadir = /var/mysql/data

启动mysql

bin/mysqld_safe --user=mysql &

netstat -nutlp | grep 3306

vim /etc/profile

#add

PATH=$PATH:/usr/local/mysql/bin

. /etc/profile

#move include file

vim /etc/ld.so.conf.d/mysql.conf

#add

/usr/local/mysql/lib

#reread configure

ldconfig -v

ln -sv /usr/local/mysql/include /usr/include/mysql

ls /usr/include/mysql/

#service mysql start

cp support-files/mysql.server /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig mysqld on

service mysqld restart

注意如果不删匿名用户，即便是你设了root密码只要输入

mysql -u.. 回车就可以进入数据库系统

-u 后跟任意字符

主从mysql工作的原理图：

主mydsql配置：

1. grant replication slave, replication client on *.* to tom@‘192.168.0.%’ identified by '123456';

2.

log_bin = mysql-bin

server_id = 1

show master status

从mysql配置：

3。server_id = 2

relay_log = mysql-relay-bin

log_slave_updates = 1

read_only = 1

mysql

mysql>change master to myster host ="server1"

mysql>maser_user='rep1'

mysql>master_password ='password',

mysql>master log_file='mysql-bin.001',

mysq>master_log_pos=0;

show slave status\G

start slave
