二、实施过程

1、搭建MySQL主从复制

-时间同步，主节点搭建时间同步服务器

--安装ntp

[[email protected] src]# yum -y install ntp

--配置ntp，添加

[[email protected] src]# vim /etc/ntp.conf
server 127.127.1.0
fudge 127.127.1.0 stratum 8

--重启服务

[[email protected] src]# service ntpd restart

--从节点时间同步

[[email protected] ~]# yum -y install ntpdate
[[email protected] ~]# ntpdate 192.168.10.130
 8Dec 14:16:14 ntpdate[28137]: step time server 192.168.10.130 offset 1.107709sec
-编译安装MySQL
[r[email protected] src]# yum -y installncurses-devel

--安装cmake

[[email protected] src]# tar zxfcmake-2.8.6.tar.gz
[[email protected] src]# cd cmake-2.8.6
[[email protected] cmake-2.8.6]# ./configure&& gmake && gmake install

--安装MySQL

[[email protected] src]# tar zxfmysql-5.5.22.tar.gz
[[email protected] src]# cd mysql-5.5.22
[[email protected] mysql-5.5.22]# cmake-DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DSYSCONFDIR=/etc-DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all&& make && make install

--优化调整

[[email protected] mysql-5.5.22]# cpsupport-files/my-medium.cnf /etc/my.cnf
[[email protected] mysql-5.5.22]# cpsupport-files/mysql.server /etc/init.d/mysqld
[[email protected] mysql-5.5.22]# chmod +x /etc/init.d/mysqld
[[email protected] mysql-5.5.22]# chkconfig --addmysqld
[[email protected] mysql-5.5.22]# echo"PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
[[email protected] mysql-5.5.22]# source/etc/profile

--初始化数据库

[[email protected] mysql-5.5.22]# useradd -M -s/sbin/nologin mysql
[[email protected] mysql-5.5.22]# chown -Rmysql:mysql /usr/local/mysql
[[email protected] mysql-5.5.22]#/usr/local/mysql/scripts/mysql_install_db --user=mysql--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data/

--启动服务

[[email protected] ~]# service mysqld start
Starting MySQL..                                           [确定]
[[email protected] ~]# chkconfig mysqld on
[[email protected] ~]# mysqladmin -u rootpassword '123456'
-配置master主服务器

--修改配置文件

[[email protected] ~]# vim /etc/my.cnf
log-bin=master-bin     #修改
log-slave-updates=true #修改
server-id       = 11   #增加

--重启服务

[[email protected] ~]# service mysqld restart
Shutting down MySQL.                                       [确定]
Starting MySQL..                                           [确定]

--给从服务器授权

[[email protected] ~]# mysql -uroot -p123456
mysql> grant replication slave on *.* to'slave'@'192.168.10.%' identified by '123456';
Query OK, 0 rows affected (0.00 sec)
 
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
 
mysql> show master status;
+-------------------+----------+--------------+------------------+
| File              | Position | Binlog_Do_DB |Binlog_Ignore_DB |
+-------------------+----------+--------------+------------------+
| master-bin.000001 |      336 |              |                  |
+-------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
-配置从服务器

--修改配置文件

[[email protected] ~]# vim /etc/my.cnf
server-id       = 22   #修改
relay-log=relay-log-bin      #增加
relay-log-index=slave-relay-bin.index #增加

--重启服务

[[email protected] data]# service mysqld restart

--登陆MySQL，配置同步

---根据主服务器的file和position,配置master_log_file和master_log_pos参数

[[email protected] data]# mysql -uroot –p
mysql> change master tomaster_host='192.168.10.130',master_user='slave',master_password='123456',master_log_file='master-bin.000001',master_log_pos=336;
Query OK, 0 rows affected (0.07 sec)

--启动同步

mysql> start slave;

Query OK, 0 rows affected (0.00 sec)

 

mysql> show slave status\G;

*************************** 1. row***************************

               Slave_IO_State: Waiting formaster to send event

                  Master_Host: 192.168.10.130

                  Master_User: slave

                  Master_Port: 3306

                Connect_Retry: 60

              Master_Log_File:master-bin.000001

         Read_Master_Log_Pos: 336

               Relay_Log_File:relay-log-bin.000002

                Relay_Log_Pos: 254

       Relay_Master_Log_File: master-bin.000001

             Slave_IO_Running: Yes

            Slave_SQL_Running: Yes #确保两个yes

-测试主从复制

--在主服务器上新建数据库

[[email protected] ~]# mysql -uroot -p123456
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.01 sec)
 
mysql> create database db_test;
Query OK, 1 row affected (0.00 sec)
 
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| db_test            |
| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.00 sec)

--从服务器如果同步显示，则表示成功

[[email protected] ~]# mysql -uroot -p123456
mysql> show databases;
+--------------------+
| Database           |
+--------------------+

| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.12 sec)

 

2、搭建MySQL读写分离

-在主机amoeba上安装Java环境
[[email protected] src]# chmod +xjdk-6u14-linux-x64.bin
[[email protected] src]# ./jdk-6u14-linux-x64.bin
[r[email protected] src]# mv jdk1.6.0_14//usr/local/jdk1.6

--添加环境变量

[[email protected] src]# vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.6
exportCLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
exportPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
export AMOEBA_HOME=/usr/local/amoeba/
export PATH=$PATH:$AMOEBA_HOME/bin
[[email protected] src]# source /etc/profile
[[email protected] src]# java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build1.6.0_14-b08)
Java HotSpot(TM) 64-Bit Server VM (build14.0-b16, mixed mode)
-安装amoeba
[[email protected] src]# mkdir /usr/local/amoeba
[[email protected] src]# tar zxfamoeba-mysql-binary-2.2.0.tar.gz -C /usr/local/amoeba/
[[email protected] src]# chmod -R 755 /usr/local/amoeba/
[[email protected] src]#/usr/local/amoeba/bin/amoeba
amoeba start|stop  #显示此说明成功
-配置amoeba读写分离

--节点服务器开放权限

mysql> grant all on *.* totest@'192.168.10.%' identified by '123456';
Query OK, 0 rows affected (0.01 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

--修改配置文件-amoeba.xml

[[email protected] ~]# vim/usr/local/amoeba/conf/amoeba.xml

--启动amoeba，8066/tcp

[[email protected] ~]#/usr/local/amoeba/bin/amoeba start &
