    BSD單用戶級與多用戶級啟動腳本/etc/rc.d/rc.1

    時間: 若木635 分享

      BSD單用戶級啟動腳本/etc/rc.d/rc.1

      腳本執(zhí)行后,除了內(nèi)核后臺程序和init外都將關(guān)閉。登陸程序?qū)㈤_啟,su:S1:respawn:/sbin/sulogin指定的功能。只有root用戶才能用系統(tǒng)。

      --------------------------------/etc/rc.d/rc.1-------------------------------

      #!/bin/sh

      # 卸載遠程文件系統(tǒng)

      echo "Unmounting remote filesystems..."

      /bin/umount -a -tnfs

      #下面兩個信號后,除了內(nèi)核后臺程序和init外都將關(guān)閉。

      echo "Sending all processes the TERM signal..."

      /sbin/killall5 -15

      sleep 1

      echo "Sending all processes the KILL signal..."

      /sbin/killall5 -9

      ----------------------------end of /etc/rc.d/rc.1----------------------------

      BSD多用戶終端腳本/etc/rc.d/rc.2

      /etc/rc.d/rc.2

      #!/bin/sh

      # 這個例子里網(wǎng)卡ip設(shè)置為192.168.0.2 。子網(wǎng)掩碼為255.255.255.0,網(wǎng)關(guān)為192.168.0.1

      ### You may wish to add some commands changing sysctl states here, for example:

      # echo 1 > /proc/sys/net/ipv4/ip_forward # enable IP forwarding

      # echo 1 > /proc/sys/net/ipv4/tcp_syncookies # defend against SYN flood

      #設(shè)置網(wǎng)卡

      echo "Setting up loopback networking..."

      /sbin/ifconfig lo 127.0.0.1

      /sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo

      echo "Setting up eth0..."

      /sbin/ifconfig eth0 192.168.0.1 broadcast 192.168.0.255 netmask 255.255.255.0

      /sbin/route add -net default gw 192.168.0.1 netmask 0.0.0.0

      # 掛載遠程文件系統(tǒng)

      echo "Mounting remote filesystems..."

      /bin/mount -a -v -tnfs

      ### you can create additional scripts for specific (networking) tasks,

      ### for example NFS, which needs a lot of daemons to work (see 3.2)

      ### or your firewall script:

      # 有防火墻則去下面注釋

      # if [ -x /etc/rc.d/rc.firewall ]; then

      # echo "Restoring firewall rules..."

      # /etc/rc.d/rc.firewall

      # fi

      # 網(wǎng)絡(luò)的一些后臺程序,如NFS

      # if [ -x /etc/rc.d/rc.netdaemons ]; then

      # echo "Starting network daemons..."

      # /etc/rc.d/rc.netdaemons

      # fi

      # 用戶個人配制文件

      if [ -x /etc/rc.d/rc.local ]; then

      /etc/rc.d/rc.local

      fi
