gearman安装

apt-get install gearman gearman-server libgearman-dev

配置bindip

/etc/defalut/gearman-job-server

PARAMS="--listen=0.0.0.0"

/etc/init.d/gearman-job-server start

/etc/init.d/gearman-job-server status

mysql_config无就安装下面的

apt-get install libmysqld-dev libmysqlclient-dev

mysql 查找plugin目录：

show variables like '%plugin%';

编译安装 udf

CPPFLAGS=" -Werror -Wno-unused-but-set-variable" ./configure --with-mysql=/usr/bin/mysql_config --libdir=/usr/lib/mysql/plugin

make install

Libraries have been installed in:

/usr/lib/mysql/plugin

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR'

flag during linking and do at least one of the following:

- add LIBDIR to the `LD_LIBRARY_PATH' environment variable

during execution

- add LIBDIR to the `LD_RUN_PATH' environment variable

during linking

- use the `-Wl,-rpath -Wl,LIBDIR' linker flag

- have your system administrator add LIBDIR to `/etc/ld.so.conf'
