配置：mysql-proxy?? 192.168.1.163

#mysql-proxy -r 192.168.0.162:3306 -b 192.168.0.164:3306 -s /usr/local/mysql-proxy/share/doc/mysql-proxy/rw-splitting.lua &

-r 指定讀服務器

-b 指定些服務器

-s 指定使用那個lua(我這們這邊做的讀寫分離所以選rw-splitting.lua)

執行命令后提示：

2016-03-18 00:32:38: (critical) plugin proxy 0.8.5 started

# netstat -antup|grep proxy

tcp ? 0 ? 0 ? 0.0.0.0:4040 ? ? ? ? ?0.0.0.0:* ? ? ? ? ? ? ? LISTEN ? ? ?3323/mysql-proxy

測試：

#mysql -u user1 -p123456 -P 4040 -h 192.168.0.163(拿mysql-proxy做pc機測試。)

mysql> use db ;

Reading table information for completion of table and column names

You can turn off this feature to get a quicker startup with -A

Database changed

mysql> select *from test;

? ? server default db:?

? ? client default db: db

? ? syncronizing

+------+

| id ? |

+------+

| ? 62 |

+------+

1 row in set (0.00 sec)

mysql> insert into test values(63);

Query OK, 1 row affected (0.00 sec)

mysql> select *from test;

+------+

| id ? |

+------+

| ? 62 |

+------+

1 row in set (0.00 sec)

測試寫數據沒有問題，但是select *from test;查看不到，說明現在已經實現讀寫分離。

檢測數據登錄1.162從（只讀服務器）

mysql> use db;

Database changed

mysql> select *from test;

+------+

| id ? |

+------+

| ? 62 |

+------+

1 row in set (0.00 sec)

檢測數據登錄1.164從（寫服務器）

mysql> use db;

Database changed

mysql> select *from test;

+------+

| id ? |

+------+

| ? 64 |

| ? 63 |

+------+

2 rows in set (0.00 sec)

在1.163上面insert into test values(63);添加的63來到（1.64寫服務器）。

讀寫分離成功。

那下面我們配置mysql主從:

mysql-master? 192.168.1.164 （主）

#vim /etc/my.conf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

log-bin=mysqllog

server-id=1 ? ? ? ? ? ?添加這三行。

binlog-do-db=db?

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

登錄數據庫：主服務器

mysql> grant all on *.* to user2@'%' identified by '123456';?

Query OK, 0 rows affected (0.00 sec)

建個同步的賬戶.

mysql> drop table test; 刪除test表格

#service mysqld restart

mysql-slave?? 192.168.1.162 （從）

#vim /etc/my.conf

[mysqld]

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

server-id=2?

master-host=192.168.0.164 ? ? t添加這4行

master-user=user2?

master-password=123456?

[mysqld_safe]

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

登錄數據庫：從服務器

mysql> drop table test; 刪除test表格

#service mysqld restart

登錄：mysql-master? 192.168.1.164 （主）

mysql> use db;

Database changed

mysql> ?create table test (id int );?

Query OK, 0 rows affected (0.03 sec)

mysql> ?insert into test values(62);?

Query OK, 1 row affected (0.00 sec)

mysql> ?insert into test values(63);?

Query OK, 1 row affected (0.00 sec)

建立test表。

登錄：mysql-slave?? 192.168.1.162 （從）

mysql> use db ;

Database changed

mysql> select *from test;

+------+

| id ? |

+------+

| ? 62 |

| ? 63 |

+------+

2 rows in set (0.00 sec)

數據已同步過來。
