咋感覺像寫論文一樣。。。

一. mysql安裝

Ø 開始安裝

將下載的mysql-5.1.60.tar.gz檔案拷貝到/usr/local/src目錄下。版本最好都是統一的 ！

以root使用者在CentOS的終端中輸入以下命令，開始安裝MySQL程式。

#cd /usr/local/src/

#groupadd mysql

#useradd -g mysql -s /sbin/nologin mysql

#tar xzvf mysql-5.1.60.tar.gz

#cd mysql-5.1.60/

* 在編譯之前，由於缺少ncurses安裝包，必須yum install ncurses-devel

#./configure --prefix=/usr/local/mysql --with-extra-charset=all --without-isam --exec-prefix=/usr/local/mysql --with-tcp-port=3306 --with-innodb --with-partition

#make

#make install

Ø MySQL的啟動配置

以root使用者在CentOS的終端中輸入以下命令，讓MySQL支援service 啟動。

#cd /usr/local/mysql/

#chown -R mysql .

#chgrp -R mysql .

#cd /usr/local/src/mysql-5.1.60/support-files

#cp my-medium.cnf /etc/my.cnf

   修改my.cnf檔案，修改內容如下。

替換skip-locking為skip-external-locking

   在my.cnf中新增如下內容。

datadir=/usr/local/mysql2/data

basedir=/usr/local/mysql2

#cp mysql.server /etc/init.d/mysqld

#chmod 755 /etc/init.d/mysqld

#chkconfig --add mysqld

#chkconfig mysqld on

Ø MySQL DB的安裝

#mkdir /usr/local/mysql/data

#mkdir /usr/local/mysql/log

#chown -R mysql:mysql /usr/local/mysql/data

#chmod -R 755 /usr/local/mysql/data

#/usr/local/mysql/bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &

Ø MySQL的service啟動

#service mysqld restart

Ø MySQL的手動啟動

#/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

Ø 配置MySQL的遠端連線

#mysql -h 127.0.0.1 -P 3306

mysql>use mysql;

mysql>update user set host = '%' where user = 'root';

mysql>select host, user from user;

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;

mysql>FLUSH PRIVILEGES;

二。mysql主從配置

Basic configuration of master 1，2，slave3

======================db1============================
log-error=/usr/local/mysql/log/error.log
long_query_time=5
slow_query_log=/usr/local/mysql/log/slow.log

log-bin=mysql-bin
binlog_format=ROW

server-id       = 1
#log-bin   =  /var/log/mysql/mysql-bin.log
#log-bin-index   =  /var/log/mysql/mysql-bin.index
relay-log   =  /var/log/mysql/mysql-relay-bin
relay-log-index   =  /var/log/mysql/mysql-relay-bin.index
expire_logs_days = 10
max_binlog_size = 100M
log_slave_updates  =1

auto_increment_increment=2
auto_increment_offset=1
bind-address = 0.0.0.0

===================db2====================
log-error=/usr/local/mysql/log/error.log
long_query_time=5
slow_query_log=/usr/local/mysql/log/slow.log

log-bin=mysql-bin
binlog_format=ROW

server-id       = 2
#log-bin   =  /var/log/mysql/mysql-bin.log
#log-bin-index   =  /var/log/mysql/mysql-bin.index
relay-log   =  /var/log/mysql/mysql-relay-bin
relay-log-index   =  /var/log/mysql/mysql-relay-bin.index
expire_logs_days = 10
max_binlog_size = 100M
log_slave_updates  =1

auto_increment_increment=2
auto_increment_offset=2
bind-address = 0.0.0.0

=====================db3=============================
db3修改my.cnf，確定有以下內容
 
server-id       = 3
log-bin=mysql-bin
log_slave_updates  =1

========================資料複製=============================

備份出sql：mysqldump -h127.0.0.1 -uroot -proot --lock-tables=0 --all-databases > /tmp/database-backup.sql

拷貝到其他機器：scp /tmp/database-backup.sql [email protected]:/tmp

在其他機器上執行：source /tmp/database-backup.sql

===========================建立使用者===============================

GRANT REPLICATION CLIENT                 ON *.* TO 'mmm_monitor'@'10.77.50.%' IDENTIFIED BY 'mmm_monitor';
GRANT SUPER, REPLICATION CLIENT, PROCESS ON *.* TO 'mmm_agent'@'10.77.50.%'   IDENTIFIED BY 'mmm_agent';
GRANT REPLICATION SLAVE                  ON *.* TO 'slave'@'10.77.50.%' IDENTIFIED BY 'slave';

 FLUSH PRIVILEGES;

=============================建立主從=============================

1 row in set (0.00 sec) 

(db2) mysql> CHANGE MASTER TO master_host='192.168.0.11', master_port=3306, master_user='replication', 
              master_password='replication_password', master_log_file='<file>', master_log_pos=<position>;

1 row in set (0.00 sec) 

(db1) mysql> CHANGE MASTER TO master_host = '192.168.0.12', master_port=3306, master_user='replication',
              master_password='replication_password', master_log_file='<file>', master_log_pos=<position>;

(db1) mysql> START SLAVE;

(db1) mysql> SHOW SLAVE STATUS\G
*************************** 1. row *************************** 
             Slave_IO_State: Waiting for master to send event 
                Master_Host: 192.168.0.12
                Master_User: <replication>
                Master_Port: 3306 
              Connect_Retry: 60 

然後以db2為主，然後db1為從。這樣就建立了db1,db2互相主從，db3，db4，db5從於db1.

三。ip的規劃

這些虛擬ip最後會在啟動的時候自動的由monitor分配給固定ip的db的
