--with-gd-lib=/usr/local/lib --with-gd-inc=/usr/include
3. 创建nagios 运行所需的用户，组和目录并且赋权
[root@nagios nagios-3.2.1]# groupadd nagios
[root@nagios nagios-3.2.1]# mkdir /usr/local/nagios
[root@nagios nagios-3.2.1]# useradd -g nagios nagios
[root@nagios nagios-3.2.1]# chown -R nagios:nagios /usr/local/nagios/
4. 安装
[root@nagios nagios-3.2.1]# make all
5. 安装主程序,CGI 和HTML 文件
