DNS的服务器的编译安装，及缓存名称服务器配置
###################################废话不多说直接上货#############################################
###########这里我编译安装的版本是bind-9.10
实验前准备：
[root@localhost local]# yum groupinstall "server platform development" [root@localhost ~]# yum groupinstall "development tools" -y [root@localhost local]# groupadd -r -g 53 named [root@localhost local]# useradd -r -g 53 -u 53 named [root@localhost local]# id named uid=53(named) gid=53(named) groups=53(named)
[root@localhost src]# tar -xf bind-9.10.1-P1.tar.gz -C /usr/local/ [root@localhost bind-9.10.1-P1]# ./configure --prefix=/usr/local/bind9 --sysconfdir=/etc/named/ --disable-chroot --enable-threads --disable-ipv6 [root@localhost bind-9.10.1-P1]#make && make install [root@localhost init.d]# vim /etc/profile.d/named.sh ############添加环境变量 1 PATH=/usr/local/bind9/bin:/usr/local/bind9/sbin:$PATH [root@localhost init.d]# . /etc/profile.d/named.sh
注意：到此为止我们编译的named全部处理完毕但是，此时的named是没有配置文件的，根域的解析文件也没有。
###################################提供man文件##############################################
1，一次性查看man文件的方式 [root@localhost man]# man -M /usr/local/bind9/share/man/ named 2，通过添加man文件的方式 [root@localhost man1]# cp * /usr/share/man/man1/ [root@localhost man3]# cp * /usr/share/man/man3/ [root@localhost man5]# cp * /usr/share/man/man5/ [root@localhost man8]# cp * /usr/share/man/man8/ 3，通过指明man的文件变量的方式 43 MANPATH /usr/man 44 MANPATH /usr/share/man 45 MANPATH /usr/local/man 46 MANPATH /usr/local/share/man 47 MANPATH /usr/X11R6/man 48 MANPATH /usr/local/bind9/share/man ###添加路径，但是不会立即生效
