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
starting mysql/etc/init.d/mysql: line 159: kill: (3871) - 没有那个进程

[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
warning: mysql-server-community-5.0.51a-0.rhel4.i386.rpm: v3 dsa signature: nokey, key id 5072e1f5
