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-0.49\libmemcached-0.48\libmemcached-0.47\libmemcached-0.30\libmemcached-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-0.49\libmemcached-0.48\libmemcached-0.47\libmemcached-0.44\libmemcached-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:
[root@sunss24 libmemcached-0.34]#./configure \
--with-memcached=/home/memcache/bin/memcached
[root@sunss24 libmemcached-0. 34]# make
[root@sunss24 libmemcached-0. 34]# make install
再运行一下memstat,算成功了
[root@sunss24 ~]# ln -s /usr/local/lib/libmemcached.so.3 /usr/lib/
[root@sunss24 ~]# cd memcached_functions_mysql-0.9
[root@sunss24 memcached_functions_mysql-0.9]# ./configure \
--with-mysql=/usr/local/mysql/bin/mysql_config \
--libdir=/usr/local/mysql/lib/
[root@sunss memcached_functions_mysql-0.9]# make && make install
安装完成后将UDFs加载到MySQL中:
mysql> show variableslike"%plugin%";
+---------------+-----------------------------------+
| Variable_name | Value |
+---------------+-----------------------------------+
| plugin_dir | /usr/local/mysql/lib/mysql/plugin |
+---------------+-----------------------------------+
1 rowinset(0.00 sec)
[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 mailin/var/spool/mail/root
[root@sunss ~]# cp /usr/local/mysql/lib/libmemcached_functions_mysql.so /usr/local/mysql/lib/mysql/plugin/
[root@sunss ~]# cd memcached_functions_mysql-0.9/
[root@sunss ~]#cd sql/
mysql> source install_functions.sql;
查看各种版本:
mysql>selectmemc_udf_version();
+--------------------+
| memc_udf_version() |
+--------------------+
| 0.9 |
+--------------------+
1 rowinset(0.00 sec)

遇到问题:
Nopackage'libmemcached'found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed softwareina non-standard prefix.
Alternatively, you maysetthe environment variables DEPS_CFLAGS
andDEPS_LIBStoavoid the needtocall pkg-config.
See the pkg-config man pageformore details.
解决办法:
[root@sunss24 memcached_functions_mysql-0.9]# whereis pkgconfig
[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:
效率测试:
插入:
include_once("gettime.php");
$btime= getmicrotime();
$i= 0;
$mem=newMemcache();
$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
$re_sql="insert into urls (id,url) values ($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."\r\n";
?>
1000条,插入时间:runTime: 1.4072
删除:
include_once("gettime.php");
$btime= getmicrotime();
$i= 0;
$mem=newMemcache();
$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
//$re_sql = "insert into urls (id,url) values ($i, 'www.gongchang.com')";
$re_sql="delete from urls where id=".$i;
//echo "re_sql_1: ".$re_sql."\n";
$res= mysql_query($re_sql,$local_db);
$i++;
}
mysql_close($local_db);
$etime= getmicrotime();
$runTime=round($etime-$btime, 4);
echo"runTime: ".$runTime."\r\n";
?>
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
