●mysql 5.0.46安装配置
mysql 5.0.46是企业版本，貌似双数版本都是企业版本了。个人觉得代码质量要比社区版本要好一些。大家可以下载，免费使用。并不需要向mysql公司交钱。
cd /usr/local/src
# wget
# tar xzvf mysql-5.0.46.tar.gz
# cd mysql-5.0.46
修改mysql 客户端最大连接数， 默认的只有100,远远达不到我们的要求。
# vi sql/mysqld.cc
搜索找到下面一行：
{"max_connections", OPT_MAX_CONNECTIONS,
"The number of simultaneous clients allowed.", (gptr*) &max_connections,
(gptr*) &max_connections, 0, GET_ULONG, REQUIRED_ARG, 100, 1, 16384, 0, 1,
0},
将其中的100改为1500, 当然小点也可以，根据你的需要来，不建议改的太大。
{"max_connections", OPT_MAX_CONNECTIONS,
"The number of simultaneous clients allowed.", (gptr*) &max_connections,
(gptr*) &max_connections, 0, GET_ULONG, REQUIRED_ARG, 1500, 1, 16384, 0, 1,
0},
保存。

编译的时间可能会比较长，毕竟优化的比较厉害。
# mamake ske install
编译安装完成后执行后续操作：
# useradd mysql //添加 mysql 用户
# cd /usr/local/mysql
# bin/mysql_install_db --user=mysql
# chown -R root:mysql . //设置权限，注意后面有一个 "."
# chown -R mysql /var/lib/mysql //设置 mysql 目录权限
# chgrp -R mysql . //注意后面有一个 "."
# cp share/mysql/my-medium.cnf /etc/my.cnf
# cp share/mysql/mysql.server /etc/rc.d/init.d/mysqld //开机自动启动 mysql。
# chmod 755 /etc/rc.d/init.d/mysqld
# chkconfig --add mysqld
# /etc/rc.d/init.d/mysqld start //启动 MySQL
# bin/mysqladmin -u root password "password_for_root"
