001:
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.
configure failed for srclib/apr

原因：未安装C编译器所致。

解决办法：安装所有的‘开发工具’（因我无法确定是哪个，所以全部安装了）。再执行编译，编译成功！

002:
1) install selinux-policy-targeted-sources from your OS vendor
2) add the following two lines to /etc/selinux/targeted/src/policy/domains/program/mysqld.te:
allow mysqld_t random_device_t:chr_file read;
allow mysqld_t urandom_device_t:chr_file read;
3) cd to /etc/selinux/targeted/src/policy and issue the following command:
make load

[root@localhost soft]# service mysql status
MySQL is not running, but lock exists [失败]

原因：安装前，，未检查到系统默认安装了mysql-devel-4.1.7-4.RHEL4.1所致。

解决办法：卸载刚才安装的Mysql版本，同时卸载mysql-devel-4.1.7-4.RHEL4.1，然后重新安装即可！

最终结果：
[root@localhost soft]# rpm -ivh MySQL-server-community-5.0.51a-0.rhel4.i386.rpm
