Nginx Introduction I will not wordy, first say the installation environment of the system.
0. Installation Environment
System: Ubuntu 14.04
PHP version: 5.5.9
Existing Server Software: Apache (basic not affected, will be mentioned later)
1. Installing Nginx
sudo apt-get install NginxIf you have Apache installed, and Apache is running at this time, then please modify the configuration file (no students skip directly):

The question is, how do multiple processes listen to the same port? Can't bind fail?
First fork, then bind.
First Bind,listen, then fork.
If two separate processes attempt to bind to the same port, the sockets in the two processes are two separate files in the file system, and if they try to bind to the same NIC, they will inevitably clash. Therefore, BIND will return an error di
@ localhost)28> gettableinfo = fun (item)-> mnesia: table_info (Dictionary, item) end.
# Fun
(A @ localhost)29> getfragnodes = fun ()-> mnesia: Activity (sync_dirty, gettableinfo, [frag_dist], mnesia_frag) end. # Fun
Test:
(A @ localhost)30> getfragnodes ().
[{B @ localhost, 0}, {c @ localhost, 0}, {A @ localhost, 1}]
Now you can add a shard. Through the node list returned by getfragnodes, mnesia can add the new Shard to a relatively idle node by load balancing:
(A @ localhost)35

Fortunately, XML syntax is very close to SGML (and hence HTML), so there is little difference in syntax.Above, you have explained all the specifications that XHTML documents must follow, most of which are already defined by HTML. Additional cases, such as all elements must be closed and the rules of the empty element, are new。When using empty element syntax for XML, add a space before the trailing slash (/), such as Most older browsers will put the XML declarationAs content is displayed, it is

It is to allow all the elements in the distributed system to have unique identification information, and do not need to through the central control side to do the identification information designation. In this way, everyone can create a UUID that does not clash with others. In this case, there is no need to consider the name duplication problem when the database is established. A

is that there are hundreds of languages all over the world, Japan has made it Shift_JIS in Japanese, South Korea has made it into the Korean language, and Euc-kr countries have standards that inevitably clash, and the result is that in the mixed text of multiple languages, there will be garbled characters.As a result, Unicode emerges. Unicode unifies all languages into a set of encodings, so there is no more garbled problem.The Unicode standard is al
