1.解压tar.bz2
tar jxvf android-ndk-r5c-linux-x86.tar.bz2
2.linux IP可以访问域名无法访问
vi /etc/resolv.conf
添加，
nameserver 202.106.46.151
3.linux 安装deb文件
sudo dpkg -i ibus-sogoupycc_0.2.5-1_i386.debibus-sogoupycc-data_0.2.5-1_all.deb
4.UBUNTU清理内存（sudo su下执行）
echo 1 > /proc/sys/vm/drop_caches
5.UBUNTU查看内存free -m6.给VMWARE虚拟机硬盘瘦身

http://www.linuxcast.net不错的linux学习网站，最近看视频才想起这个博客，继续记录吧
7,程序暂停，前台，后台执行的问题
正在执行的进程可以使用Ctrl+Z暂停掉
jobs看后台作业，带序号的
可以使用fg <序号>将暂停的jobs前台运行
bg <序号>将暂停的Jobs后台运行
8.ESC+.可以得到上次命令的参数9.创建硬盘分区
使用fdisk /dev/vdb，对vdb做操作，进入操作界面按m根据提示操作即可，创建主分区，创建扩展分区，在扩展分区基础上创建逻辑分区
10.创建逻辑卷1.需要创建物理卷（PV），会分成若干物理扩展PE（4M大小），使用命令pvcreate /dev/vdb，使用pvs/pvdisplay查看2.在该物理卷上创建逻辑卷组（VG） test，vgcreate test /dev/vdb，创建完使用vgs/vgdisplay查看下3.在该卷组中创建2G大小的逻辑卷（LV) test-1， lvcreate -n test-1 -L 2G test ，使用lvs/lvdisplay查看4.之后mkfs再mount即可使用，路径是/dev/{vg-name}/{lv-name}5.umount之后删除逻辑卷，lvremove /dev/{vg-name}/{lv-name}6.删除卷组， vgremove /dev/{vg-name}7.清除物理卷，pvremove /dev/vdb11.screen的使用
screen创建一个会话screen -ls 列出已存在的会话screen -r {id} 切换到指定id的会话Ctrl+a d 退出当前的会话，但会话还在后台，可以resume在会话中Ctrl+d则完全结束会话在会话中Ctrl+a c可创建新窗口在会话中Ctrl+a S可以横向分屏，Ctrl+a |可竖向分屏在会话中Ctrl+a tab可以再分屏中切换在会话中Ctrl+a {数字}可以切换窗口，即Ctrl+a c创建的，Ctrl+a n是下一个窗口，Ctrl+a p是前一个窗口在会话中Ctrl+a A可以设定窗口名Ctrl+a ?查看帮助screen用vi打开退出后依然保留，http://stackoverflow.com/questions/9979318/how-to-avoid-emacs-or-vi-remaining-on-your-screen-after-closing-when-using-gnu，在~/.screenrc增加altscreen on，再ctrl+a :source ~/.screenrc
12.missing LSB tags最近在debian上安装screen出现这个问题导致安装不完整，出现类似下面的问题
insserv: warning: script 'K01monitor' missing LSB tags and overridesinsserv: warning: script 'monitor' missing LSB tags and overridesinsserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!insserv: Starting monitor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!
解决见http://forum.directadmin.com/showthread.php?t=42174与其他的服务脚本对比，需要对应服务/etc/init.d/monitor加上（因为这里是monitor服务，其他服务也对应文件加就行）
### BEGIN INIT INFO# Provides: monitor# Required-Start: $syslog# Required-Stop: $syslog# Should-Start: #named# Default-Start: 2 3 4 5# Default-Stop: 0 1 6# Short-Description: Start and stop directadmin# Description: DirectAdmin### END INIT INFO
