Centos/RHEL安装没setup命令 最小化装完centos 5.5/RHEL系统后,发现用setup的配置命令没有了.12[root@localhost ~]# setup-bash: setup: command not found这时就要手动去安装这个快速配置程序了.1[root@localhost ~]# yum install setuptool ntsysv system-config-network system-config-keyboard# yum install setuptool发现setup命令可以用了,可是系统服务,网络配置,键盘配置,时区配置不见了.安装下这几个配置程序安装系统服务配置# yum install ntsysv安装网络配置# yum install system-config-network安装键盘时区配置# yum install system-config-keyboardsystem-config-network system-config-keyboard这两个包的依赖很多,能手工改就手动改吧,没特殊应用就不用装了.本方法适用于centos/redhat 5.x

ESXi 5 and VNCHello, I have configured my ESXi 5 VMs for VNC - to enable me to VNC to the console for each of the VMs. But I cannot work out how to obfuscate the password, I wonder if anyone can help? I have set it up as follows: Stop each VMLog in to the ESXi host using SSHAdd the following to the VM's .vmx file: RemoteDisplay.vnc.enabled = "TRUE" RemoteDisplay.vnc.port = "5901"RemoteDisplay.vnc.password = "password"When I restart the VM, I see that the following line has been added to the .vmx file RemoteDisplay.vnc.key = "long random string blah blah blah......." Now, when I try to connect to the server using a VNC client, I am not being allowed in. It is not asking for a password, it is showing me a blank screen.You configuration works, but you need to open the firewall on ESXi... First step is build a new rule like this:~ # cat /etc/vmware/firewall/vnc.xml <!-- Firewall configuration information for VNC ...

Linux VPS Nginx+PHP 安装ionCube 今天下载了一个whmcs，在自己的VPS上测试一下，但是提示：Site error: the file /home/test/whmcs/index.php requires the ionCube PHP Loader ioncube_loader_lin_5.2.so to be installed by the site administrator.上面的提示是没有安装ionCube的原因。首先，执行uname -a 查看系统是32位还是64位，打开http://www.ioncube.com/loaders.php页面根据Linux是32位还是64位下载适当的软件包，比如我的是32位的，切换到/usr/local/目录，执行cd /usr/local ，wget http://downloads2.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.gz 下载，再执行tar zxvf ioncube_loaders_lin_x86.tar.gz 解压软件包。修改/usr/local/php/etc/php.ini 在文件尾部添加如下代码：[ionCube Loader]zend_extension="/usr/local/ioncube/ioncube_loader_lin_5.2.so"如果以前装有Zend Optimizer，安装ionCube会和Zend Optimizer发生冲突，再执行/usr/local/php/php-fpm reload 时会发生如下错误：The Loader must appear as the first entry in the php.ini file in Unknown on line 0须将Zend Optimizer的代码删除，如LNMP中是如下代码...
