mysql架构精选

◆主从架构
1.安装服务（主从）
yum -y install mysql*
/etc/init.d/mysqld start
2.修改配置文件:/etc/my.conf(主从)
vi /etc/my.conf
log-bin=mysql-bin ###开启二进制日志文件
server-id=131 ###声明服务器ID，不重复即可
/etc/init.d/mysqld restart
3.1进入主—数据库
mysqladmin -uroot password '123'
mysql -uroot –p
##创建从服务器登录用户
##grant replication slave on *.* to '用户'@'%' identified by '密码';
grant replication slave on *.* to 'master'@'%' identified by '123';
show master status; ##查看二进制文件名，以及大小
3.2进入从-数据库
mysqladmin -uroot password '123'
mysql -uroot –p
##确定从主服务器同步
##change master to master_host='主服务器IP',master_user='用户',master_password='密码',master_log_file='二进制文件',master_log_pos=文件空间大小;
change master to master_host='192.168.116.131',master_user='master',master_password='123',master_log_file='mysql-bin.000001',master_log_pos=385;
##启动同步
start slave;
##查看同步服务开启状态
show slave status\G;
4.测试
主：create database aa;
从：show databases;
◆主从从架构
1.安装服务（主从）

start slave;
##查看同步服务开启状态
show slave status\G;
4.测试

◆主主架构（互为主从）
###服务器有数据的情况，需要手动先同步一致，cp重定向到mysql
1.安装服务（主主）
yum -y install mysql*
/etc/init.d/mysqld start
2.修改配置文件:/etc/my.conf(主主)
vi /etc/my.conf
log-bin=mysql-bin ###开启二进制日志文件
server-id=131 ###声明服务器ID，不重复即可
###下面几个看实际情况使用，实验环境可忽略
replicate-do-db=test ###需要同步的数据库
binlog-ignore-db=mysql ###不需要同步的数据库
binlog-ignore-db=information_schema ##不需要同步的数据库
auto-increment-increment=2 ###为了保证含有自增长的不会冲突
auto-increment-offset=1 ###为了保证含有自增长的不会冲突
log-slave-updates=true
/etc/init.d/mysqld restart
3.1进入主1—数据库 ip:192.168.116.131
mysqladmin -uroot password '123'
mysql -uroot –p
##创建从服务器登录用户
##grant replication slave on *.* to '用户'@'%' identified by '密码';
grant replication slave on *.* to 'master'@'%' identified by '123';
flush privileges;
show master status; ##查看二进制文件名，以及大小
##确定从主服务器同步
##change master to master_host='主服务器IP',master_user='用户',master_password='密码',master_log_file='二进制文件',master_log_pos=文件空间大小;
change master to master_host='192.168.116.132',master_user='slave',master_password='123',master_log_file='mysql-bin.000001',master_log_pos=384;
##启动同步
start slave;
##查看同步服务开启状态
show slave status\G;
3.2进入主2-数据库 ip:192.168.116.132
mysqladmin -uroot password '123'
mysql -uroot –p
##创建从服务器登录用户
##grant replication slave on *.* to '用户'@'%' identified by '密码';
grant replication slave on *.* to 'slave'@'%' identified by '123';
show master status; ##查看二进制文件名，以及大小
##确定从主服务器同步
##change master to master_host='主服务器IP',master_user='用户',master_password='密码',master_log_file='二进制文件',master_log_pos=文件空间大小;
change master to master_host='192.168.116.131',master_user='master',master_password='123',master_log_file='mysql-bin.000001',master_log_pos=247;
##启动同步
start slave;
##查看同步服务开启状态
show slave status\G;
4.测试
主1：create database aa;show databases;主2:show databases;
主2：create database aa;show databases;主1:show databases;
◆主主从架构
1.安装服务（主主从）
yum -y install mysql*
/etc/init.d/mysqld start
2.主配置文件:/etc/my.conf
2.1两台主服务器
vi /etc/my.conf
log-bin=mysql-bin ###开启二进制日志文件
server-id=131和132 ###声明服务器ID，不重复即可
/etc/init.d/mysqld restart
2.2从服务器
vi /etc/my.cnf
[mysqld_multi]
mysqld=/usr/bin/mysqld_safe
mysqladmin=/usr/bin/mysqladmin
log=/tmp/multi.log
[mysqld131]
port=3306
pid-file=/var/lib/mysqla/mysqld.pid
datadir=/var/lib/mysqla
socket=/var/lib/mysqla/mysql.sock
server-id=129
user=mysql
[mysqld132]
port=3307
pid-file=/var/lib/mysqlb/mysqld.pid
datadir=/var/lib/mysqlb
socket=/var/lib/mysqlb/mysql.sock
server-id=129
user=mysql
3.1 主1进入数据库
mysqladmin -uroot password '123'
mysql -uroot -p
grant replication slave on *.* to 'master1'@'%' identified by '123';
show master status;
3.2 主2进入数据库
mysqladmin -uroot password '123'
mysql -uroot -p
grant replication slave on *.* to 'master2'@'%' identified by '123';
show master status;
3.3 从服务器
mysql_install_db --datadir=/var/lib/mysqla --user=mysql ###初始化mysqla数据库
mysql_install_db --datadir=/var/lib/mysqlb --user=mysql ###初始化mysqlb数据库
cd /var/lib
chown -R mysql /var/lib/mysqla/ ##修改文件权限
chown -R mysql /var/lib/mysqlb/ ##修改文件权限
mysqld_multi --defaults-file=/etc/my.cnf start 131 ##主1id号，开起数据库01，为主1备份
mysqld_multi --defaults-file=/etc/my.cnf start 132 ##主2id号，开起数据库02，为主2备份
测试端口：netstat -an |grep 3306&3307
mysqladmin -u root password '123' -S /var/lib/mysqla/mysql.sock ##建立131数据库密码
mysqladmin -u root password '123' -S /var/lib/mysqlb/mysql.sock ##建立132数据库密码

####进入mysqla ----131数据库配置
mysql -uroot -p -S /var/lib/mysqla/mysql.sock
change master to master_host='192.168.116.131',master_user='master1',master_password='123',master_log_file='mysql-bin.000001',master_log_pos=247;
start slave;
show slave status\G;
exit

####进入mysqlb -----132数据库配置
mysql -uroot -p -S /var/lib/mysqlb/mysql.sock
change master to master_host='192.168.116.132',master_user='master2',master_password='123',master_log_file='mysql-bin.000001',master_log_pos=247;
start slave;
show slave status\G;
exit
4.测试
主1备份测试：
主1: create database aa;
从:
mysql -uroot -p -S /var/lib/mysqla/mysql.sock
show databases;
主2备份测试:
主2:create database bb;
从：
mysql -uroot -p -S /var/lib/mysqlb/mysql.sock
show databases;

◆mysql读写分离 -----amoeba
1.两台数据库主从关系
yum -y install mysql*
/etc/init.d/mysqld start
vi /etc/my.conf
log-bin=mysql-bin ###开启二进制日志文件
server-id=131 ###声明服务器ID，不重复即可
/etc/init.d/mysqld restart
##主数据库
mysqladmin -uroot password '123'
mysql -uroot –p
grant all privileges on *.* to 'amoeba'@'%' identified by '123';
show master status; ##查看二进制文件名，以及大小

###从数据库
mysqladmin -uroot password '123'
mysql -uroot –p
change master to master_host='192.168.116.131',master_user='amoeba',master_password='123',master_log_file='mysql-bin.000001',master_log_pos=382;
grant all privileges on *.* to 'amoeba'@'%' identified by '123';

##查看同步服务开启状态
show slave status\G;
#启动同步
start slave;
###测试
主：create database aa;
从：show databases;

2.配置amobe服务器
yum -y install lrzsz mysql
rz amoeba-n.iso
mkdir /iso
mount -o loop amoeba-n.iso /iso/
cp /iso/* .
tar zxvf jdk-7u40-linux-x64.gz
mv jdk1.7.0_40/ /usr/local/jdk
vi /etc/profile
#JDK
JAVA_HOME=//usr/local/jdk
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH export CLASSPATH
source /etc/profile

###测试：echo $PATH java -version

unzip amoeba-mysql-1.3.1-BETA.zip -d /usr/local/amoeba
chmod -R a+x /usr/local/amoeba/bin/
vi /usr/local/amoeba/conf/amoeba.xml
