ubunt11 安装mysql_ubuntu11.10安装mysql+handlersocket

1.安装mysql：(不管要啥，一股脑都装上)

sudo apt-get install mysql-serversudo apt-get install mysql-clientsudo apt-get install libmysqlclient-devsudo apt-get install libmysqld-dev

2.下载mysql和handlersocket源代码：

3.解压

sudo tar -zxvf mysql-5.1.62.tar.gz -C /usr/local/src/

sudo tar -zxvf handlersocket_1.0.6-80-g88bf1e0.orig.tar.gz -C /usr/local/src/

4.编译安装handler socket

cd /usr/local/src/ahiguti-HandlerSocket-Plugin-for-MySQL-395fa55/

sudo ./autogen.sh

小插曲：

这里出现：

错误1

Searching libtoolize...-e WARNING: Cannot Found libtoolize... input libtool command^C

解决：

sudo apt-get install libtool

错误2

Searching libtoolize...-e FOUND: libtoolize ->libtoolize

Searching aclocal...-e WARNING: Cannot Found aclocal... input aclocal command^C

解决：

sudo apt-get install autotools-devsudo apt-get install automake

插曲结束~

sudo ./configure --with-mysql-source=../mysql-5.1.62 --with-mysql-bindir=/usr/bin --with-mysql-plugindir=/usr/lib/mysql/plugin

with-mysql-source 表示MySQL源代码目录，with-mysql-bindir 表示MySQL二进制可执行文件目录(也就是 mysql_config 所在目录，可以用whereis mysql_config找到)，with-mysql-plugindir 表示MySQL插件目录

如果不清楚这个目录在哪，可以按如下方法查询：

mysql> SHOW VARIABLES LIKE 'plugin%';

+---------------+-----------------------+

| Variable_name | Value                 |

+---------------+-----------------------+

| plugin_dir    | /usr/lib/mysql/plugin |

+---------------+-----------------------+

sudo make & make install

5.修改mysql配置文件my.cnf，添加相关端口配置：

# sudo vi /etc/my.cnf

[mysqld]

loose_handlersocket_port= 9998# the port number to bind to (forread requests)

loose_handlersocket_port_wr= 9999# the port number to bind to (for writerequests)

loose_handlersocket_threads= 16# the number of worker threads (forread requests)

loose_handlersocket_threads_wr= 1# the number of worker threads (for writerequests)

open_files_limit= 65535# to allow handlersocket accept many concurren connections,make open_files_limit as large as possible.

6.登陆mysql

bobo@master:/usr/local/src$ mysql -u root -p

Enter password:

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

Query OK,0 rows affected (0.30sec)

插曲二：

中间又出现错误了。。

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

ERROR1126 (HY000): Can't open shared library'/usr/lib/mysql/plugin/handlersocket.so'(errno: 2 cannot open shared object file: No such file or directory)

莫名其妙的，结果我又单独make一下，再make install一下，就好了。。

我也不知道跟这个又没有关系。。。

插曲二终

通过show processlist 能在MySQL里看到HandlerSocket的线程了：

mysql>show processlist->;+----+-------------+-----------------+---------------+---------+------+-------------------------------------------+------------------+

| Id | User | Host | db | Command | Time | State | Info |

+----+-------------+-----------------+---------------+---------+------+-------------------------------------------+------------------+

也可以查看端口占用来验证你的mysql装好了：

bobo@master:~$ sudo lsof -i :9998COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

mysqld14173 mysql 30u IPv4 49030 0t0 TCP *:9998(LISTEN)

bobo@master:~$ sudo lsof -i :9999COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

mysqld14173 mysql 77u IPv4 49032 0t0 TCP *:9999 (LISTEN)

7.简单测试

看了许多教程，有许多问题，觉得这个的参考价值大一些：
