several different directories at once, Cassandra automatically synchronizes data for all directories. Also in the log configuration file log4j-server.properties has a default setting log file directory: Log4j.appender.r.file=/var/log/cassandra/system.log
In general, the default configuration can be, unless you have special storage requirements, so now there are two scenarios: first, the default configuration to create the relevant directory, and the second is to modify the configuration fil

Work within the same namespace
Think carefully about the following code:
myapp1.php
Execution results:
Applib1myconst applib1myfunction Applib1myclass::whoami Namespace Import
You can import namespaces using the use operator, such as:
myapp2.php
Execution results:
Applib2myconst Applib2myfunction Applib2myclass::whoami namespace alias
Namespace aliases may be the most useful idea, and ali
: = $ (x) barx: = Later
It is equivalent to:
Y: = foo barx: = Later
It is worth mentioning that this method, the previous variable can not use the following variables, only the previously defined variables. If this is the case:
Y: = $ (x) barx: = foo
Then, the value of y is "bar", not "foo bar".
Here are some simpler variables to use, let's take a look at a complex example that includes the function of make, the conditional expression, and the use of a system variable "Makelevel":

. LoginShell exploitation of initial files
. Initial files used by second-level Shell
. Reasonable utilization of the two types of files

After you enter the username and password in Login, the Shell described in [/etc/passwd] will be started. The standard SHELL in LINUX is Bash, if you want to confirm the SHELL you are using, enter

Listing 1 shows some examples, indicating that the prompt string (from the PS1 environment variable) is different from other examples in this article. It is a useful function to include your id in the prompt string.

Although this can be done, I suggest you do not do this. it is best to define only one namespace in each file to avoid confusion.
Sub-namespace
PHP allows you to define a hierarchical namespace so that the database can be subdivided. the sub-namespace is separated by a backslash character (\), for example:
