MySQL主從同步、讀寫分別設置裝備擺設步調。本站提示廣大學習愛好者:(MySQL主從同步、讀寫分別設置裝備擺設步調)文章只能為提供參考,不一定能成為您想要的結果。以下是MySQL主從同步、讀寫分別設置裝備擺設步調正文


如今應用的兩台辦事器曾經裝置了MySQL,滿是rpm包裝的,能正常應用。
為了不不用要的費事,主從辦事器MySQL版本盡可能堅持分歧;
情況:192.168.0.1 (Master)
192.168.0.2 (Slave)
MySQL Version:Ver 14.14 Distrib 5.1.48, for pc-linux-gnu (i686) using readline 5.1
1、登錄Master辦事器,修正my.cnf,添加以下內容;
server-id = 1 //數據庫ID號, 為1時表現為Master,個中master_id必需為1到232–1之間的一個正整數值;
log-bin=mysql-bin //啟用二進制日記;
binlog-do-db=data //須要同步的二進制數據庫名;
binlog-ignore-db=mysql //分歧步的二進制數據庫名;這個同步後據說很費事,我沒有同步;
log-bin=/var/log/mysql/updatelog //設定生成的log文件名;
log-slave-updates //把更新的記載寫到二進制文件中;
slave-skip-errors //跳錯誤誤,持續履行復制;
2、樹立復制所要應用的用戶;
mysql>grant replication slave on *.* to [email protected] identified by '********'
3、重啟mysql;
/usr/bin/mysqladmin -uroot shutdown;
/usr/bin/mysql_safe &
4、如今備份Master上的數據;
鎖定後我直接tar.gz data這個庫文件;
mysql>FLUSH TABLES WITH READ LOCK;
cd /var/lib/mysql
tar data.tar.gz data
接著直接履行了長途scp;
scp ./data.tar.gz [email protected]:/var/lib/mysql
5、登錄Slave數據庫辦事器,修正my.cnf;
server-id = 3 //2曾經被用在另外一個辦事器上了,假如今後要再加Slave號接著往後數就OK了;
log-bin=mysql-bin
master-host = 192.168.0.1
master-user = test
master-password = ******
master-port = 3306
master-connect-retry=60 //假如發明主辦事器斷線,從新銜接的時光差;
replicate-ignore-db=mysql //不須要備份的數據庫;
replicate-do-db=data //須要備份的數據庫
log-slave-update
slave-skip-errors
6、解壓適才從Master scp過去的文件,此處不消改權限、屬主,默許沒有轉變,可以依據現實情形停止修正;
7、上述完成後,可以啟動slave了;檢查slave狀況;
mysql>slave start;
mysql>show slave status\G;
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event
Master_Host: 192.168.0.1
Master_User: test
Master_Port: 3306
Connect_Retry: 60
Master_Log_File: updatelog.000001
Read_Master_Log_Pos: 106
Relay_Log_File: onlinevc-relay-bin.000013
Relay_Log_Pos: 1069
Relay_Master_Log_File: updatelog.000001
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
Replicate_Do_DB: data
Replicate_Ignore_DB: mysql
Replicate_Do_Table:
Replicate_Ignore_Table:
Replicate_Wild_Do_Table:
Replicate_Wild_Ignore_Table:
Last_Errno: 0
Last_Error:
Skip_Counter: 0
Exec_Master_Log_Pos: 106

Last_IO_Errno: 0
Last_IO_Error:
Last_SQL_Errno: 0
Last_SQL_Error:
1 row in set (0.00 sec)

ERROR:

8、檢查Master下面的狀況;
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| updatelog.000012 | 15016 | data | mysql |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
因而可知二者的File、Position存在成績,所要要去Slave上設置對應主庫的Master_Log_File、Read_Master_Log_Pos;履行以下語句;
mysql>slave stop;
mysql>CHANGE MASTER TO MASTER_HOST='192.168.0.1',MASTER_USER='test', MASTER_PASSWORD='******',MASTER_LOG_FILE='updatelog.000012',MASTER_LOG_POS=15016;
確保 Slave_IO_Running: Yes 、Slave_SQL_Running: Yes都要為YES能力證實Slave的I/O和SQL停止正常。
9、解鎖主庫表;
UNLOCK TABLES;
到此主從MySQL辦事器設置裝備擺設完成,測試成果以下;
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| updatelog.000012 | 717039 | data | mysql |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
mysql> show slave status\G;

#################################### 以下是MySQL數據庫讀寫分別操作步調 ##########################################
此處應用MySQL本身(Mysql-proxy)的署理完成數據庫的讀寫分別;
所須要裝置包以下;
1、check-0.9.8
2、glib-2.18.4
3、libevent-2.0.6-rc
4、lua-5.1.4
wget http://www.lua.org/ftp/lua-5.1.4.tar.gz
5、pkg-config-0.23
6、mysql-5.0.56
7、mysql-proxy-0.8.0
http://mysql.cdpa.nsysu.edu.tw/Downloads/MySQL-Proxy/mysql-proxy-0.8.0.tar.gz

其余裝置包地址其時沒有記下載地址,不外年夜部門都在這個網站上找的;http://sourceforge.net/
&&&&&&&&&& 裝置開端 &&&&&&&&
1、tar -zxvf check-0.8.4.tar.gz
cd check-0.8.4
./configure
make
make install
2、tar -zxvf glib-2.18.4.tar.gz //體系rpm包能夠版本低湧現了成績3;
./configure
make
make install
3、tar -zxvf libevent-2.0.6-rc.tar.gz
cd libevent-2.0.6-rc
./configure --prefix=/usr/local/libevent
make && make install
4、tar -zxvf lua-5.1.4.tar.gz
INSTALL_TOP= /usr/local/lua // 為了把lua裝置到/var/lib/lua下,故要修正其下的Makefile;
或許直接履行:sed -i 's#INSTALL_TOP= /usr/local#INSTALL_TOP= /usr/local/lua#' Makefile
root@testmysql [/software/lua-5.1.4]# make
Please do
make PLATFORM
where PLATFORM is one of these:
aix ansi bsd freebsd generic linux macosx mingw posix solaris
See INSTALL for complete instructions.
這處是要你選擇辦事器所應用的平台;
履行:make linux //此處履行後湧現了毛病,處理方法鄙人面成績處理區1處,此處先跳過;
再履行:make install
設置情況變量:
export LUA_CFLAGS="-I/usr/local/lua/include" LUA_LIBS="-L/usr/local/lua/lib -llua -ldl" LDFLAGS="-L/usr/local/libevent/lib -lm"
export CPPFLAGS="-I/usr/local/libevent/include"
export CFLAGS="-I/usr/local/libevent/include"

5、tar -zxvf pkg-config-0.23.tar.gz
cd pkg-config-0.23
./configure
make
make install
裝置完以後要履行:cp etc/lua.pc /usr/local/lib/pkgconfig/lua5.1.pc //緣由見上面的成績處理區2處;
6、裝置MySQL客戶端;
由於此辦事器體系是默許裝置了MySQL,沒有裝置客戶端,我又裝了client、devel以下所示已裝置的rpm包;
root@testmysql [/software/lua-5.1.4]# rpm -qa | grep MySQL
MySQL-client-5.1.48-0.glibc23
MySQL-bench-5.0.91-0.glibc23
MySQL-test-5.1.48-0.glibc23
MySQL-shared-5.1.48-0.glibc23
MySQL-server-5.1.48-0.glibc23
MySQL-devel-5.1.48-0.glibc23
爾後的Mysql-proxy時老是一向報錯,編譯不外去,無法之下用源碼包客戶端;(此時的rpm包都沒有卸載,直接履行了上面的裝置)//此處成績見成績處理區4處;
tar zxvf mysql-5.0.56.tar.gz //此處我直接應用了mysql的5.0.56的源碼包;
cd mysql-5.0.56
./configure --prefix=/usr/local/mysql --without-server
make && make install

7、tar xvf mysql-proxy-0.8.0.tar.gz
cd mysql-proxy-0.8.0
./configure --prefix=/usr/local/mysql-proxy --with-mysql=/usr/local/mysql --with-lua //成績處理處4有引見;
Make && Make install

8、在/var/lib/bin創立mysql-proxy.sh,內容以下;
#!/bin/bash
LUA_PATH="/usr/local/mysql-proxy/lib/mysql-proxy/lua/?.lua" /usr/local/mysql-proxy/bin/mysql-proxy --proxy-backend-addresses=192.168.0.1:3306 --proxy-read-only-backend-addresses=192.168.0.2:3306 --proxy-lua-script=/usr/local/mysql-proxy/lib/mysql-proxy/rw-splitting.lua >> /var/log/mysql-proxy.log &
然後加上可履行權限;
chmod a+x /var/lib/bin/mysql-proxy.sh
履行:/var/lib/bin/mysql-proxy.sh 啟動辦事;
9、驗證能否開戶了:4040、4041;
root@testmysql [/usr/local/bin]# netstat -an | grep 404*
tcp 0 0 0.0.0.0:4040 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:4041 0.0.0.0:* LISTEN
10、測試讀寫分別,此步略過,一切設置裝備擺設曾經完成。

&&&&&&&&&&&&&&&&&&&&&&&&&&& 成績處理區 &&&&&&&&&&&&&&&&&&&&&&&&&&&&
1、在裝置的第四步履行make linux時報錯以下:

make: *** [linux] Error 2

處理辦法:yum install libtermcap-devel
yum install ncurses-devel
yum install libevent-devel
yum install readline-devel

2、裝置MySQL-proxy時報錯:
checking for LUA... configure: error: Package requirements (lua5.1 >= 5.1) were not met:

No package 'lua5.1' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LUA_CFLAGS
and LUA_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
處理方法:
cp etc/lua.pc /usr/local/lib/pkgconfig/lua5.1.pc

3、裝置MySQL-proxy時報錯:
checking for GLIB... configure: error: Package requirements (glib-2.0 >= 2.16.0) were not met:

No package 'glib-2.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GLIB_CFLAGS
and GLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
處理方法:
1、檢查體系曾經裝置glib的rpm包;
glibc-2.5-49.el5_5.4
glibc-headers-2.5-49.el5_5.4
glib2-2.12.3-4.el5_3.1
glibc-common-2.5-49.el5_5.4
glibc-devel-2.5-49.el5_5.4
2、下載裝置glib-2.18.4.tar.gz

4、剛開端應用體系裡rpm所指定的mysq_config時,mysql-proxy裝置報錯,信息以下;
configure: error: mysql_config not exists or not executable, use $ ./configure --with-mysql=/path/to/mysql_config
看到贊助裝置文檔裡請求以下:
--with-mysql[=PATH] Include MySQL support. PATH is the path to 'mysql_config'。
處理方法就是:裝置包中的第6步。
