MySQL可以使用MySQL的mysql-udf-http进行效率测试 ,这次不使用rest架构,而是使用:libmemcached和memcached_functions_mysql,测试版本是:libmemcached-0.34.tar.gz和memcached_functions_mysql-0.9.tar.gz,其它版本配对都有问题,我安装测试过有问题的版本有:
memcached_functions_mysql-1.1在: libmemcached-0.49libmemcached-0.48libmemcached-0.47libmemcached-0.30libmemcached-0.43\libmemcached-0.42 下安装有错误 memcached_functions_mysql-0.10在: libmemcached-0.42下安装有错误 memcached_functions_mysql-0.8在: libmemcached-0.49libmemcached-0.48libmemcached-0.47libmemcached-0.44libmemcached-0.43 libmemcached-0.42下安装有错误
MySQL测试版本:5.1.55,操作系统Centos5.4 64bit,内存2G
安装libmemcached-0.34和memcached_functions_mysql-0.9:
[chinastor.com-root@sunss24 libmemcached-0.34]#./configure --with-memcached=/home/memcache/bin/memcached [chinastor.com-root@sunss24 libmemcached-0. 34]# make [chinastor.com-root@sunss24 libmemcached-0. 34]# make install 再运行一下memstat,算成功了 [chinastor.com-root@sunss24 ~]# ln -s /usr/local/lib/libmemcached.so.3 /usr/lib/ [chinastor.com-root@sunss24 ~]# cd memcached_functions_mysql-0.9 [chinastor.com-root@sunss24 memcached_functions_mysql-0.9]# ./configure --with-mysql=/usr/local/mysql/bin/mysql_config --libdir=/usr/local/mysql/lib/ [chinastor.com-root@sunss memcached_functions_mysql-0.9]# make && make install
安装完成后将UDFs加载到MySQL中:
mysql> show variables like "%plugin%"; +---------------+-----------------------------------+ | Variable_name | Value | +---------------+-----------------------------------+ | plugin_dir | /usr/local/mysql/lib/mysql/plugin | +---------------+-----------------------------------+ 1 row in set (0.00 sec) [chinastor.com-root@sunss ~]# find / -name "libmemcached_functions_mysql.so" /usr/local/mysql/lib/libmemcached_functions_mysql.so /root/memcached_functions_mysql-0.9/src/.libs/libmemcached_functions_mysql.so You have new mail in /var/spool/mail/root [chinastor.com-root@sunss ~]# cp /usr/local/mysql/lib/libmemcached_functions_mysql.so /usr/local/mysql/lib/mysql/plugin/ [chinastor.com-root@sunss ~]# cd memcached_functions_mysql-0.9/ [chinastor.com-root@sunss ~]#cd sql/ mysql> source install_functions.sql;
查看各种版本:
mysql> select memc_udf_version(); +--------------------+ | memc_udf_version() | +--------------------+ | 0.9 | +--------------------+ 1 row in set (0.00 sec) mysql> select memc_libmemcached_version(); +-----------------------------+ | memc_libmemcached_version() | +-----------------------------+ | 0.34 | +-----------------------------+ 1 row in set (0.00 sec) mysql>
遇到问题:
No package 'libmemcached' 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 DEPS_CFLAGS and DEPS_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
解决办法:
[chinastor.com-root@sunss24 memcached_functions_mysql-0.9]# whereis pkgconfig [chinastor.com-root@sunss24 memcached_functions_mysql-0.9]# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig
导出所有memcache内容:
使用:memcached-hack.zip
效率测试:
插入:
< php include_once("gettime.php"); $btime = getmicrotime(); $i = 0; $mem = new Memcache(); $mem->addServer('192.168.0.10', 11212); $local_db = mysql_connect("192.168.0.208", "sunss", "123456"); if(!$local_db) { die('Could not connect: '.mysql_error()); } $local_db_sel = mysql_select_db("test", $local_db); mysql_query("set names utf8", $local_db); while ( $i < 1000) { $re_sql = "insert into urls (id,url) values ($i, 'www.gongchang.com')"; $res = mysql_query($re_sql, $local_db); $i++; } mysql_close($local_db); $etime = getmicrotime(); $runTime = round($etime - $btime, 4); echo "runTime: ".$runTime."rn"; >
1000条,插入时间:runTime: 1.4072

删除1000条,运行时间:runTime: 1.5534
结论:每秒query大概650条记录,比上次的mysql-udf-http快多了原文链接:http://www.cnblogs.com/sunss/archive/2011/06/07/2074435.html
