Mysql主从复制的实现
MySQL是一个开放源码的小型关联式数据库管理系统，开发者为瑞典MySQL AB公司。MySQL被广泛地应用在Internet上的中小型网站中。由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点，许多中小型网站为了降低网站总体拥有成本而选择了MySQL作为网站数据库。Mysql内建的复制功能是构建大型、高性能应用程序的基础；将Mysql的数据分布到多个系统上，而这种分布的机制是通过将一台Mysql服务器的数据复制到其他主机(slave)上，由slave主机读取Master服务器的二进制日志文件然后重新在本地执行一遍来实现。做Mysql主从复制时，所有更新操作都只能在Master服务器，而Slave服务只负责更新自己的数据并提供查询操作。
Mysql复制主要能解决的有问题有：数据的分布、负载均衡、数据备份、高可用以及容错性。
Mysql的复制原理基本上可以分为以下3步：
1.在Master服务器将改变的数据记录到二进制日志(binary log)中（这些记录叫做二进制日志事件）
2.Slave服务器将Master服务器上的二进制日志拷贝到自己的中继日志(relay-log)中
3.Slave服务器读取中继日志中的事件，然后将改变的数据写入到自己的数据库中
第1步：在Master服务器上记录二进制日志。在每个更新数据的事务完成之前，Master服务器都会将数据更改记录到二进制日志中。即使事务在执行期间是交错的，Mysql也会串行地将事务写入到二进制日志中。在把事件写入二进制日志之后，Master服务器告诉存储引擎可以提交事务了
第2步：Slave服务器把主服务器的二进制日志拷贝到自己的硬盘上，进入所谓的“中继日志”中。首先，它启动一个工作线程，叫I/O线程，这个I/O线程开启一个普通的客户端连接，然后启动一个特殊的二进制日志转储进程（它没有相应的SQL命令）。这个转储进程Master服务器的二进制日志中读取数据。它不会对事件进行轮询。如果3跟上了Master服务器，就会进入休眠状态并等待有新的事件发生时Master服务器发出的信号。I/O线程把数据写入Slave服务器的中继日志中
第3步：SQL线程读取中继日志，并且重放其中的事件，然后更新Slave服务器的数据。由于这个线程能跟上I/O线程，中继日志通常在操作系统的缓存中，所以中继日志的开销很低。SQL线程执行事件也可以被写入Slave服务器自己的二进制日志中，它对于有些场景很实用
上图中显示了在Slave服务器有两个运行的线程，在Master服务器上也有一个运行的线程：和其他普通连接一样，由Slave服务器发起的连接，在Master服务器上同样拥有一个线程。
系统环境及拓扑
系统版本：CentOS 6.3_x86_64
Mysql版本：mysql-5.6.17
下载地址：http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.17.tar.gz
1.准备工作
1.1修改master、slave主机名
master主机名:mysql_master
slave主机名：mysql_slave
1.2在master和slave上配置主机名解析
# cat >> /etc/hosts << EOF
172.16.10.72 mysql_master master
172.16.10.61 mysql_slave slave
EOF
1.3时间同步
# yum install -y ntpdate
# ntpdate ntp.fudan.edu.cn
# crontab -e
* * * * /usr/sbin/ntpdate ntp.fudan.edu.cn
2.安装Mysql（master与slave分别进行）
# groupadd mysql
# useradd -s /sbin/nologin -g mysql mysql
# tar xf mysql-5.6..tar.gz
# cd mysql-5.6.# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
# make && make install# chown -R mysql.mysql /usr/local/mysql
# cd /usr/local/mysql/scripts/
# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data #初始化mysql数据库，#指定mysql数据文件的存放位置
# cd ..
# cd support-files/# cp mysql.server /etc/rc.d/init.d/mysql
# cp my-default.cnf /etc/my.cnf
# chkconfig --add mysql
# chkconfig mysql on
# service mysql start
Starting MySQL..... SUCCESS!# ln -s /usr/local/mysql/bin/* /usr/bin/
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql遇到报错如下：
- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake: (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake: (FIND_CURSES)
cmake/readline.cmake: (MYSQL_USE_BUNDLED_EDITLINE)
CMakeLists.txt: (MYSQL_CHECK_EDITLINE)
-- Configuring incomplete, errors occurred!
解决办法：
yum -y install ncurses-devel
find / -name CMakeCache.txt|xargs rm -f
然后重新执行cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
3.配置主从复制
3.1在master上建立用于slave服务器复制数据的帐户
[root@mysql_master ~]# mysql
mysql> GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* to eivll0m@'172.16.10.61' IDENTIFIED by 'password';
Query OK, rows affected (0.10 sec)
mysql> FLUSH PRIVILEGES;
Query OK, rows affected (0.06 sec)
mysql> SHOW GRANTS FOR eivll0m@'172.16.10.61';
+---------------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for eivll0m@172.16.10.61 |
+---------------------------------------------------------------------------------------------------------------------------------------------------+
| GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'eivll0m'@'172.16.10.61' IDENTIFIED BY PASSWORD '*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19' |
+---------------------------------------------------------------------------------------------------------------------------------------------------+
row in set (0.02 sec)
3.2在Slave服务器上使用授权用户连接测试
[root@mysql_slave ~]# mysql -ueivll0m -ppassword -h 172.16.10.72
Warning: Using a password on the command line interface can be insecure.
ERROR (HY000): Can't connect to MySQL server on '172.16.10.72' (113) #报错原因为master服务器iptables阻止了slave的连接，暂时先关闭即可 [root@mysql_slave ~]# mysql -ueivll0m -ppassword -h 172.16.10.72
Warning: Using a password on the command line interface can be insecure.

3.5.查看master服务器的二进制日志及二进制日志事件位置
[root@mysql_master ~]# mysql -e 'SHOW MASTER STATUS;'
+------------------+----------+--------------+------------------+-------------------+

+----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+
3.9验证：在saster服务器创建数据库，在slave服务器上验证是否复制过去
[root@mysql_master ~]# mysql -e 'CREATE DATABASE eivll0m;'
[root@mysql_master ~]# mysql -e 'SHOW DATABASES;'
+--------------------+
| Database |
+--------------------+
| information_schema |
| eivll0m |
| mysql |
| performance_schema |

+--------------------+
[root@mysql_slave ~]# mysql -e 'SHOW DATABASES;' #可以看到eimll0m数据库已经复制过去
+--------------------+
| Database |
+--------------------+
| information_schema |
| eivll0m |
| mysql |
| performance_schema |
| test |
+--------------------+
3.10在主从服务器查看二进制日志事件位置是否更新
[root@mysql_master ~]# mysql -e 'SHOW MASTER STATUS;'
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin. | | | | |
+------------------+----------+--------------+------------------+-------------------+
[root@mysql_slave ~]# mysql -e 'SHOW SLAVE STATUS\G;' | grep "Read_Master_Log_Pos"
Read_Master_Log_Pos:
由此可见，已经更新。
4.配置基于SSL的复制
由于Mysql的主从复制是明文传送的，如果在生产环境中跨网络使用主从还是明文传送，就无法保证数据的传输安全性，为了解决这一问题，我们需要加密进行传送，也就是基于SSL的加密方法进行传输数据。
4.1在master服务器搭建CA服务器
[root@mysql_master ~]# cd /etc/pki/CA/
[root@mysql_master CA]# (umask ;openssl genrsa -out private/cakey.pem )
[root@mysql_master CA]# openssl req -new -x509 -key private/cakey.pem -out cacert.pem -days
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name ( letter code) [XX]:CN
State or Province Name (full name) []:BeiJing
Locality Name (eg, city) [Default City]:ChaoYang
Organization Name (eg, company) [Default Company Ltd]:eivll0m
Organizational Unit Name (eg, section) []:Tech
Common Name (eg, your name or your server's hostname) []:mysql_master
Email Address []:master@eivll0m.com
[root@mysql_master CA]# touch index.txt
[root@mysql_master CA]# echo > serial
4.2为master创建证书申请并由CA服务器签发证书
[root@mysql_master ~]# mkdir /usr/local/mysql/ssl
[root@mysql_master ssl]# cd /usr/local/mysql/ssl
[root@mysql_master ssl]# (umask ;openssl genrsa -out master.key )
[root@mysql_master ssl]# openssl req -new -key master.key -out master.csr -days

在mastet服务器上将签署好证书申请拷贝到Slave服务器
[root@mysql_master ~]# scp /tmp/slave.crt mysql_slave:/usr/local/mysql/ssl/
4.5将CA证书拷贝到slave服务器与saster相应目录
[root@mysql_master ~]# scp /etc/pki/CA/cacert.pem mysql_slave:/usr/local/mysql/ssl/
[root@mysql_master ~]# cp /etc/pki/CA/cacert.pem /usr/local/mysql/ssl/
4.6修改master与slave服务器证书属主、属组为"mysql"用户
# chown -R mysql.mysql /usr/local/mysql/ssl
# ll /usr/local/mysql/ssl/
-rw-r--r-- mysql mysql Sep : cacert.pem
-rw-r--r-- mysql mysql Sep : master.crt
-rw-r--r-- mysql mysql Sep : master.csr
-rw------- mysql mysql Sep : master.key
4.7在master与slave服务器编辑my.cnf开启SSL加密功能
在master服务器的my.cnf文件中[mysqld]下添加如下参数
ssl #开启SSL功能
ssl_ca = /usr/local/mysql/ssl/cacert.pem #指定CA文件位置
ssl_cert = /usr/local/mysql/ssl/master.crt #指定证书文件位置
ssl_key = /usr/local/mysql/ssl/master.key #指定密钥所在位置
在slave服务器的my.cnf文件中[mysqld]下添加如下参数
ssl
ssl_ca = /usr/local/mysql/ssl/cacert.pem
ssl_cert = /usr/local/mysql/ssl/slave.crt
ssl_key = /usr/local/mysql/ssl/slave.key
4.8在master服务器查看SSL加密是否开启并创建授权一个基于密钥认证的用户
mysql> SHOW VARIABLES LIKE '%ssl%';
+---------------+---------------------------------+
| Variable_name | Value |
+---------------+---------------------------------+
| have_openssl | YES |
| have_ssl | YES |
