在psftp(sftp的命令行客户端)中进行批处理操作:
1.首先建立文件->myscript.scr,内容如下:
|
2.然后你可以运行下面命令行:
psftp user@hostname -b myscript.scr
myscript.scr中所写的内容就会执行下去
3.有什么用呢?在windows下写个批处理.bat,配合editplus上传文件,爽翻你
附命令行帮助:

I have recently had success setting up a MySQL Cluster, so I thought I’d share what I did with everyone since it was such a challenge for me to do and the documentation for how to set it up is so poor. |
######################### My Setup #################################### Here is my setup: I have two machines, Machine A and Machine B, that have requests and updates to the db balanced by a router. There is one IP address that clients use to access the db. The router distributes 50% of the requests to Machine A and the remaining 50% to Machine B. Therefore, the db on both Machine A and Machine B must be exactly the same at all times. To achieve this I used MySQL Cluster. I am running Redhat Linux 9 on both machines, and the machines are physically identical. Machine A ip = 10.0.2.39 Machine B ip = 10.0.2.38 ########################### Installing ################################ I did the following on both machines: - I installed MySql-Max (Linux (x86, glibc-2.2, static, gcc) 4.1.7 http://dev.mysql.com/get/Downloads/MySQL-4.1/mysql-max-4.1.7-pc-linux-i6 86.tar.gz/from/pick - I extracted the tar file into the root folder, and installed the mysql db by running the mysql_install_db script in the scripts directory. (In the mysql directory type- ./scripts/mysql_install_db) - I then created a config.ini file which I placed in the mysql directory. I also created a my.cnf file which I placed in the mysql/data directory. ################### Config.ini ####################################### [NDBD DEFAULT] NoOfReplicas= 2 [MYSQLD DEFAULT] [NDB_MGMD DEFAULT] [TCP DEFAULT] [NDB_MGMD] HostName= 10.0.2.39 (10.0.2.38 on machine B) [NDBD] HostName= 10.0.2.38 DataDir= /root/mysql/data [NDBD] HostName= 10.0.2.39 DataDir= /root/mysql/data [MYSQLD] [MYSQLD] [MYSQLD] ###################### My.cnf ########################## The my.cnf file on both machines is: [mysqld] ndbcluster ###################### Starting the cluster ############# To start the cluster I did the following: (please note that MySQL is installed in the /root/mysql directory) Machine A: - opened a terminal. - typed- cd mysql - typed- ./bin/ndb_mgmd - starts the cluster manager - typed- ./bin/ndbd --initial - please note, only use the '--initial' parameter if it is the first time you are starting the node. - typed- ./bin/mysqld_safe --user=root & - starts mysql. The terminal may stick here so use ctrl-c to get a new prompt. - typed- ./bin/mysql - starts the mysql monitor. - typed- use test; - to use the test database. Machine B: - follow the same steps as Machine A: ###################### Testing the cluster ############# On Machine A: - at the mysql monitor prompt - type- use test; - to use the test database. - type- create table cluster_test (i int) engine=ndbcluster; - this should create a clustered table called cluster_test. On Machine B: - at the mysql monitor prompt - type- use test; - type- show tables; - this should show the cluster_test table created on Machine A. Inserting Subsequent inserts etc. can be done at the mysql monitor prompt. Example: On Machine A: - type- insert into cluster_test values(314159); On Machine B: - type- select * from cluster_test; - should display the value 314159. ##########################################################
今天把公司的服务器从php4升级到php5,问题来了.最严重的是使用Pear::Pager类,报错如下:
Fatal error: Cannot re-assign $this in D:xampphtdocstmptest.php on line 5
看了下Pager类的构造,有如下代码:
$this = ……………..;
看来从php5开始不再支持这种对自身重新实例化的写法了,只好重写了Pager类草草收场

在pear的rss列表上看到了PHP_Beautifier 0.1.1 beta发布,便下载回来试用:
>>pear install PHP_Beautifier
………………………………………..
顺利完成,看了下帮助,还带有命令行工具,方便:
D:xamppphp>php_beautifier –help Usage: php_beautifier [options] Filter definition: |
不过试用下来,处理的不是太完美,比如复杂点php代码美化后不整齐之类的,期待更好的版本出现 [@more@]
如果你开始使用php5了,而且正好又是editplus的忠实用户,一定会为editplus的function列表无法正确显示而烦恼.这时候,我们不能怨社会,php5新增的public,private,proctectd,static关键字才是罪恶的根源,function不再是function,而是public function….
当然,这一切不会难倒我们,editplus具有很好的可定制性,以下步骤可以轻松解决这个问题:
好了,按下ctrl+F11,看看函数窗口,有没有显示出所有的函数呢?

今天给同一虚拟主机添加了两个端口,过程如下:[@more@]
今天给同一虚拟主机添加了两个端口,过程如下:
绑定端口为:80,8080
1.在httpd.conf中添加:
Listen 8080
2.复制原虚拟主机配置
以下是代码片段:
<VirtualHost *:80> ….. </VirtualHost> |
添加:
以下是代码片段:
<VirtualHost *:8080> ….. </VirtualHost> |
但是实际上有更简化的写法:
以下是代码片段:
<VirtualHost *:80 *:8080> ….. </VirtualHost> |
重启apache观察配置是否生效
Apache中目录的Option设置为Indexes后,文件和文件夹将列表出来,其中有一项是‘描述’
Description的,这个属性可以对文件进行一些描述,但是如何赋值呢?
