Use UDF to automatically sync memcached efficiency notes in Mysql _mysql

Next: MySQL uses mysql-udf-http efficiency test notes, this time not using the rest architecture, but using: libmemcached and Memcached_functions_mysql, the test version is:

Libmemcached-0.34.tar.gz and memcached_functions_mysql-0.9.tar.gz, other versions of the pairing are problematic, and I've installed the tested version with the following problems:

Copy Code code as follows:

memcached_functions_mysql-1.1 in:
Libmemcached-0.49\libmemcached-0.48\libmemcached-0.47\libmemcached-0.30\libmemcached-0.43\\libmemcached-0.42\
There is an error installing the
Memcached_functions_mysql-0.10 in:
There are errors installed under Libmemcached-0.42\
memcached_functions_mysql-0.8 in:
Libmemcached-0.49\libmemcached-0.48\libmemcached-0.47\libmemcached-0.44\libmemcached-0.43\
There are errors installed under \libmemcached-0.42\

MySQL beta version: 5.1.55, operating system Centos5.4 64bit, memory 2G

Install libmemcached-0.34 and memcached_functions_mysql-0.9,

Copy Code code as follows:

[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
Run the MemStat again, it's a success.
[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

Load the UDFs into MySQL after the installation is complete:

Copy Code code as follows:

Problem encountered:

Copy Code code as follows:

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.
The Pkg-config man page is for more details.
Solution:
[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

Conclusion: Query about 650 records per second, more quickly than the last Mysql-udf-http
