pex+linux redhat as4自動安裝薦

        最近公司有個大專案要做30臺左右的機器。要是一部一部的裝估計要死人。考慮的半天還是pex自動安裝來的好 hoho。。。。

第一步：安裝xinetd服務

xinetd-2.3.13-4.4E.1.i386.rpm （建議裝完系統後安裝，可以保證其他要裝的機子乾淨）

tftp服務包含在xinetd裡面

但是要注意啟動服務

第三步：準備檔案

將/p_w_picpaths/pxeboot裡的initrd.img  vmlinuz兩個檔案拷貝到/tftpboot裡去

將/usr/lib/syslinux/menu.c32  拷貝到/tftpboot裡去

將/usr/lib/syslinux/pxelinux.0 拷貝到/tftpboot裡去

 cp /root/anaconda-ks.cfg /var/www/html/ks.cfg

貼下我的ks.cfg檔案注意先要安裝http服務

rpm -ivh apr-*和rpm -ivh http*

[root@autoinstall pxeboot]# more /var/www/html/ks.cfg
# Kickstart file automatically generated by anaconda.
install
nfs –server=192.168.11.99 –dir=/var/ftp/pub  ##指定資源

第四步：共享資源

把系統盤上的資源考到/var/ftp/pub下然後共享出來

[root@autoinstall RPMS]# more /etc/exports
/var/ftp/pub    192.168.11.0/24(ro,sync) 

以showmount -e ip來驗證

第五步：在伺服器準備好dhcp服務並配置相關服務

rpm -ivh dhcp-3.0.1-59.EL4.i386.rpm （系統盤中獲取）

配置檔案可以從模版檔案中考取做修改

/usr/share/doc  —模版檔案庫

貼一下我的dhcpd.conf檔案

[root@autoinstall doc]# more /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
allow booting;                        
allow bootp;                                
subnet 192.168.11.0 netmask 255.255.255.0 {

# — default gateway
        option routers                  192.168.11.99;
        option subnet-mask              255.255.255.0;

#       option nis-domain               “domain.org”;
#       option domain-name              “domain.org”;
#       option domain-name-servers      192.168.1.1;

        option time-offset              -18000; # Eastern Standard Time
#       option ntp-servers              192.168.1.1;
#       option netbios-name-servers     192.168.1.1;
# — Selects point-to-point node (default is hybrid). Don`t change this unless
# — you understand Netbios very well
#       option netbios-node-type 2;

        range dynamic-bootp 192.168.11.128 192.168.11.254;
        default-lease-time 21600;
        max-lease-time 43200;
        next-server 192.168.11.99;
        filename “pxelinux.0”; 
}

default linux
prompt 0

label linux
        kernel vmlinuz
        append initrd=initrd.img ks=http://192.168.11.99/ks.cfg

哪的可以去網上找找，可以訪問下http://192.168.11.99/ks.cfg

看是否可以訪問ks.cfg檔案。

至此一個簡單的安裝到此完成。
