HandlerSocket安装

HandlerSocket安装

1、下载HandlerSocket

https://github.com/DeNA/HandlerSocket-Plugin-for-MySQL

2、查看你服务器mysql的版本，下载对应的源代码包并解压

3、安装HandleSocket

unzip HandlerSocket-Plugin-for-MySQL-master .zip

./autogen.sh

 ./configure --with-mysql-source=/root/mysql-5.6.26/ --with-mysql-bindir=/home/mysql/mysql/bin/ --with-mysql-plugindir=/home/mysql/mysql/lib/plugin/ 

其中：

--with-mysql-source：指定MySQL源码所在目录

--with-mysql-bindir：指定mysql_config所在目录

--with-mysql-plugindir：指定MySQL插件的存储路径

执行make编译安装：

make && make install

4、mysql相关设置

（1）将下面写入my.cnf中，重启数据库

  loose_handlersocket_port=9998

# the port number to bind to (for read requests)

loose_handlersocket_port_wr = 9999

# the port number to bind to (for write requests)

loose_handlersocket_threads = 16 # 指定读线程数目

# the number of worker threads (for read requests)

loose_handlersocket_threads_wr = 1 # 指定写线程数目

# the number of worker threads (for write requests)

open_files_limit = 65535

innodb_buffer_pool_size=1024M

innodb_log_file_size=512M

innodb_log_files_in_group = 3

open_files_limit = 65535

innodb_adaptive_hash_index=1

（2）在mysql里加载HandlerSocket插件：

mysql>install plugin handlersocket SONAME 'handlersocket.so';

mysql>show plugins;#查看插件是否加载成功。

5、查看端口

lsof -i -P|grep mysql

mysqld    2646   mysql   17u  IPv4  14234      0t0  TCP *:9998 (LISTEN)

mysqld    2646   mysql   35u  IPv4  14257      0t0  TCP *:9999 (LISTEN)

mysqld    2646   mysql   37u  IPv6  14272      0t0  TCP *:3306 (LISTEN)
