MySQL配置读写分离在这里你再也不用担心高手省略了大段代码了，因为我也是新手。下面开整先安装luaLua 是一个小巧的脚本语言。Lua由标准C编写而成，代码简洁优美，几乎在所有操作系统和平台上都可以编译，运行。一个完整的Lua解释器不过200k，在目前所有脚本引擎中，Lua的速度是最快的。这一切都决定了Lua是作为嵌入式脚本的最佳选择。先安装可能的依赖包[plain] view plain copy print?[root@bogon ~]# yum -y install gcc* gcc-c++* autoconf* automake* zlib* libxml* ncurses-devel* libmcrypt* libtool* flex* pkgconfig*  libevent* glib* readline-devel      [root@bogon ~]# mkdir /opt/install/    [root@bogon ~]# cd /opt/install/    [root@bogon install]# wget http://www.lua.org/ftp/lua-5.1.4.tar.gz    [root@bogon install]# tar zxvf lua-5.2.3.tar.gz    [root@...

Touchscreen This page is a documentation of my dealings with various touchscreen devices I've encountered. In my experience, most modern devices work out of the box with both 10.04 LTS or 12.04 LTS, but lack the proper calibration or configuration. Some older devices, especially those embedded in laptops such as GD Itronix line of rugged computers, use serial interfaces which lack the configuration to work in Linux. The methods documented here should work with other distros as well. Global Dynamics Itronix GoBook XR-1This is a rugged laptop I picked up from ebay for a good price, which the seller wiped with Ubuntu 10.04 due to the expense of Microsoft's Windows relicensing fee. The device has an integrated serial touchscreen, and the manufacturer is notorious for hiding any and all documentation on legacy devices such as this one. With a little trial and error however, it's relatively simple to configure this and similar devices. This method should work for most G...
