eaccelerator 安装

[不指定 2010/06/01 16:37 | by Totti ]
http://eaccelerator.net/wiki/InstallFromSource

When you have only one php install, it's safe to run these commands in the source directory:

phpize
./configure
make

The phpize and php-config are the ones that are in your path. When you have more then one php install or the phpize and php-config scripts aren't in your path then you should follow this procedure. This example has php installed in /opt/php, this is the path of the --prefix option given to the php configuration script.

export PHP_PREFIX="/opt/php"
$PHP_PREFIX/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=$PHP_PREFIX/bin/php-config
make

For more information about the options for the configure script you should read the CompileConfiguration page.

After compilation, there should be a "eaccelerator.so" file in the modules subdirectory of the eAccelerator source directory.
Step 2. Installing eAccelerator ¶

make install

This will copy the previously created eAccelerator binary to the php extension directory. When this command ends, it will print out the directory in which eAccelerator has been installed.
Step 3. Configuring eAccelerator ¶

eAccelerator can be installed both as Zend or PHP extension. When you install eAccelerator as a zend_extension you need to give the full path to the eaccelerator.so library.

If you have /etc/php.d directory, you should copy eaccelerator.ini to it and modify the default values. If not, you need to edit your php.ini file (usually /etc/php.ini).

To install as Zend extension:

zend_extension="/usr/lib/php4/eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

If you use a thread safe build of PHP you must use "zend_extension_ts" instead of "zend_extension".

To install as PHP extension:

extension="eaccelerator.so"
eaccelerator.shm_size="16"
eaccelerator.cache_dir="/tmp/eaccelerator"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

Step 4. Creating cache directory

One last very important step is creating the cache directory that you configured in the previous step. The default value is /tmp/eaccelerator It's easy because it's writable to everyone, but it isn't very smart because on a lot of systems this directory is cleaned on reboot. A better place would be /var/cache/eaccelerator. Create the directory and make sure it's writable for the user eAccelerator runs under (usually the user which you webserver runs as).

A safe bet is making it world writable. A safer and cleaner way would be to change the owner of the directory to the same user PHP runs as (most of the time the same user as Apache or Lighttpd) and set 0644 permissions.

The lazy way:

mkdir /tmp/eaccelerator
chmod 0777 /tmp/eaccelerator

MidpSSH——移动SSH客户端软件

[不指定 2010/06/01 09:10 | by Totti ]
MidpSSH是一SSH和Telnet客户端软件,可运行于MIDP 1.0 / 2.0 (J2ME) 设备上,例如 Java兼容的手机或其它移动设备等。MidpSSH 基于GPL发布,网址 www.xk72.com

MidpSSH支持 SSH1,Telnet和VT320 终端模拟,1.2+ 包括加密算法,支持SSH2 key交换。最新版本1.6支持键盘交互和代理服务器。

MidpSSH的作用

在移动终端上提供SSH和Telnet。对那些在任何地方需要登陆服务器的特别方便,不再需要找一台可以上网的电脑。需要指出的是,因为一般移动终端屏幕较小,连接也比较慢,所以不适合持久使用。

安装

可以通过http://xk72.com/wap直接上网下载安装,或者管理器安装

P.S.按官网的说明,支持绝大部分黑莓手机
服务器不重启的情况下定时自动重启apache及mysql服务,其实也大同小异。具体步骤如下:
一、每天的12点及16点重启apache及mysql服务
[root@www bin]# cd /opt/
[root@www opt]# vim reboot.txt
在reboot.txt.txt文件中输入下面的内容后保存
0 12 * * * service httpd restart
0 12 * * * service mysqld restart
0 16 * * * service httpd restart
0 16 * * * service mysqld restart
二、把新建的文件加入到cron服务中
[root@www opt]# crontab reboot.txt
[root@www opt]# crontab -l
0 12 * * * service httpd restart
0 12 * * * service mysqld restart
0 16 * * * service httpd restart
0 16 * * * service mysqld restart

Centos 上安装kloxo

[不指定 2010/05/19 12:22 | by Totti ]
CentOS是附带了httpd的unix版本,安装需要干净的系统,所以在装之前要反安装 httpd,php,mysql这些web组件。

yum remove httpd* php* mysql* -y


确定防火墙开启了7778和7777端口,以便打开kloxo。

Make sure that you open the ports 7778 and 7777 in the firewall. Otherwise you won't be able to connect to kloxo.

vi /etc/sysconfig/selinux 编辑,设置selinux=disabled,重启

You have to disable selinux by editing /etc/sysconfig/selinux and changing the line to selinux=disabled and then running

参考文档:http://wiki.lxcenter.org/Kloxo+Installation+Guide

命令:
# $ wget http://download.lxcenter.org/download/kloxo/production/kloxo-installer.sh
# $ sh ./kloxo-installer.sh --type=master


Centso下安装Kloxo出现YUM Gave Error… Trying Again的解决办法
Harry  3/20/2014 3:55:05 PM
在Centos下载安装Kloxo ,在安装过程中有可能出现YUM Gave Error… Trying Again 这样的错误,
发生这个错误的原因有3种
1,使用了64位的centos安装kloxo
2,使用了centos 6或者6以上版本安装kloxo (Kloxo 目前只能运行在 32 位的 CentOS 5或者5.X)
3,上面两则都不是但是还是出现错误:大多情况是kloxo安装到一半失败了,继续重装出现这个错误,出现这个错误的原因是:kloxo安装到一半的时候/etc/php.ini已被做了一些安装设置禁用了system这个函数。
解决方法:/etc/php.ini 里面找到 disable_functions 那几行全部注释掉就是在前面加一个分号。
然后重装开始安装kloxo就行了。
