Background leading to the site can not log。

If you have administrative privileges php.ini，Then，Directly edit php.ini，The output_buffer open (just give a value of 1024-4086),If you do not have permission to php.ini，But the server provides the function of words .htaccess，Then in .htaccess add that this thing on it：

All the php files are checked still the same。
Finally found out that there was no host in php.ini setting output_buffering。Although not yet ask them to correct，But we can try to use .htaccess。

.htaccess set as follows：
php_value output_buffering 4096

Tested 。no problem。

Replication thread

The Mysql Replication is an asynchronous replication process，From a Mysql instace(We call Master)Copied to another Mysql instance(We call it Slave)。Realization of the entire replication process between Master and Slave is done mainly by the three threads，Two threads(Sql threads and IO thread)In the end Slave，Another thread(IO thread)At the end of Master。

To achieve the MySQL Replication ，You must first open the Master end of the Binary Log(mysql-bin.xxxxxx)Features，Otherwise it is impossible to achieve。Various operations because the whole process is actually a copy Slave from the Master side to obtain the log and then himself completely in the implementation of the log in the order recorded。Open the MySQL Binary Log can be used in the process of starting MySQL Server "-log-bin" parameter options，Or my.cnf configuration file mysqld parameter set([mysqld]Section identifies the parameters after)Increase the "log-bin" Parameter。

The basic process is as follows MySQL replication：

　　1. Slave IO above the thread connecting the Master，And requests the specified log file from the specified location(Or from the beginning of the log)After the contents of the log;

　 　2. After receiving the request from the Master of Slave IO thread，Log information is read by the specified log specify the location of the IO thread is responsible for copying the information after the request，Back to the Slave IO thread ends。Addition to the information contained in the log, in addition to the return information，This also includes the name of the information returned by the end of the Master Binary Log file and its location in the Binary Log in;

　　3. Slave IO thread after receiving the information，The contents of the log of the received file are sequentially written to the Slave Relay Log end(mysql-relay-bin.xxxxxx)The very end，And records the file name and location of the read end of the Master bin-log to the master- info file，So that when the next time can be clearly read speed Master "I need a position from which bin-log log content beginning later，please send to me"

　 　4. Slave SQL thread detected Relay Log in newly added content after，Parses the contents of the Log file immediately becomes a real implementation of the Master side when those Query executable statement，And their implementation of these Query。such，Actually end in Master and Slave implementation of the same end Query，So the data is exactly the same at both ends。

Actually，In the old version，MySQL replication is not achieved at the end Slave to work together by the IO thread and the SQL thread two threads completed，But by a separate thread to do all the work。But MySQL's engineers soon discovered，Doing so there is a big risk and performance problems，Notably the following：

First of all，If you do this work independently, then by a single thread，Causes the end of the Master Copy，Binary Log Log，And parsing these logs，Then the execution of this process itself becomes a serial process，Performance will naturally be subject to greater restrictions，Replication of this architecture naturally relatively long delay。

Secondly，After this replication thread Slave side get up from Master Binary Log end，Then we need to resolve these，Restore the original end Query Master performed，Then in its own execution。During this process，Master end and is likely to have generated a lot of changes and generate a large amount of information Binary Log。If there is a fault can not be repaired at the end of this storage system Master stage，So at this stage all the changes arising will be lost forever，I can not get it back。This potential risk is particularly prominent in the Slave-side pressure is relatively large when，If the pressure is relatively large because the Slave，Log analysis and application of these logs time spent will naturally be longer，The data will also be lost more。

and so，In the latter part of the transformation，The new version of MySQL in order to minimize this risk，And improve the performance of replication，Copy the Slave-side instead of two threads to finish，That is, the aforementioned IO thread and the SQL thread。The first proposed improvement program is Yahoo!An engineer "Jeremy Zawodny"。Through this transformation，This will not only largely solve the performance problems，Shorten the delay time of asynchronous，While reducing the potential amount of data loss。

of course，Even replaced the two threads so now to collaborate after，Also there is still the possibility of Slave data latency and data loss is，After all, this replication is asynchronous。Whenever you change the data in a transaction not，These problems are there。

If you want to completely avoid these problems，We can only use the MySQL Cluster to solve。But the MySQL Cluster know when I wrote this part of，It is still a number of memory database solutions，That is, all the data including the index will need all Load into memory，This memory requirement is very large large，For the general popularity of applications can be implemented not too much。of course，Before that communicate with the MySQL CTO David when，MySQL is now achieve continuous improvement of its Cluster，One very large data do not allow a change is all the Load into memory，But merely an index of all Load into memory，I would like to believe that after the completion of the transformation will be more popular MySQL Cluster，Can be implemented will be greater。

SNR is the ratio of the page text on a web page with all the HTML code，This is also what we need to understand the basics of SEO。From how search engines in terms of，The first is that the system will crawl the entire web page download，Then extract the text inside，After analyzing remove HTML format，Clear noise，Then word，Finally, the index is stored in the library。During this process，Search engines will go through the process of de-noising，We are obviously able to know，The higher the SNR website，The higher the search engine spiders crawl efficiency，Document search spiders to be processed every day very much，How to quickly extract information web page theme is an important task。
In fact, the concept is derived from the acoustic signal to noise ratio，It refers to the ratio originally generated voice signal to noise output，Page is actually applied to not only refers to the ratio of all the code and herein，Also it includes useful information on the ratio of the current page text content with useless information。What useful information，For example, on the topic of my article is a web-noise ratio，Whole article has 1000 words，And all of the current page text has 2000 characters，The other text is unrelated to noise ratio，The information that is unrelated to the noise。and so，Web page divided into two areas to improve the signal to noise ratio：Including the optimization of code and content optimization。
one、Noise-Code
we know，The first step in the search engine noise removal is cleared HTML format，Then the first step to improve the signal to noise ratio of the page is optimized HTML code。Why do we often say，Page code to comply with W3C standards、Code to be Jian Jie、Use DIV + CSS，In fact, it is based on this principle。Actually，Many of my friends just to see the online article said to go write code like this，But I do not know why you want to do，This is what I suggest that you first learn SEO principle of reason (I know，Greater than the theoretical practice，But if the theories are not，How to practice，Not a starting point)。Remove noise code includes the following aspects：
Reduce the use JS，JS code must use to encapsulate。
The encapsulated CSS code。
Reduce DIV nesting (many of my friends do not know if the principle of，The blind pursuit of DIV + CSS，But also produced a lot of redundant code。）
Reduce picture、FLASH use
two、Noise-content
same，After the search engine extracts the text content pages，But also for secondary analysis of de-noising，That is, determine the theme of the current page。So in this process，How do we make search engines more accurately judge (issues related to sexual This is) our theme page，How to improve the relevance of a web page? It is to reduce the noise content of the page。
We very common that some e-commerce website product details，SEO may be a part of e-commerce sites do not pay attention to personnel，In the catalog explains here are some instructions on Delivery or help information，The presence of these contents，Improve the similarity of each product page，But also reduces the signal to noise ratio。The information from the user experience perspective is friendly，It is to enhance trust websites，But from the perspective of search engines is a certain disadvantage in terms of，So we can use these elements to encapsulate the call IFRAME or JS，So that both sides take care。There is also the main include the following：
Encapsulated duplicates call
Exporting a list of links to encapsulate unnecessary calls
Streamlining copyright information
Associated with an increased content of text length
The method is more than a few，It depends on how they implement their own understanding of the technology or master。Although we know that search engine noising preprocessing stage in the index page will，But if we ourselves do a good job to improve the signal to noise ratio of the page，On the one hand reduce the workload of the search engine，So as to enhance its efficiency crawl on our website，On the one hand to enhance the accuracy of the search engines judge。Then，One can imagine，Our pages are more trusted。

Here are a few steps to strengthen the security of the Zen Cart shop:
1. Delete / zc_install installation directory
After the installation is complete，Deleted from the server business / zc_install installation directory。
Do not just rename the directory，In case people know the name of the directory，Insecure。
2. Set configure.php files as read-only
The two configure.php files CHMOD(Setting permissions)Command be changed to read is important。
It is usually set to "644"，Sometimes "444"。
If the program can not be modified via FTP，You can use file management tool provided by the host to modify。
If you are using Windows Server，As long as the file is set to "Everyone", "Read Only"，If that is in IIS，User is IUSR_xxxxx，Or "System" account，International trade payment qq 1274899661 In Apache，Is "apache user" account。
3. Renamed "/ admin" directory
Modify the "admin" directory name，With a difficult to guess the name。
(Before making the following changes，Back up your files and databases。)
A- Using a text editor，Notepad e.g.，Open the file admin / includes / configure.php。
All appear / admin / local directory name into their management。
We need to modify the part:
define(’DIR_WS_ADMIN’, ‘/admin/’);
define(’DIR_WS_CATALOG’, ‘/’);
define(’DIR_WS_HTTPS_ADMIN’, ‘/admin/’);
define(’DIR_WS_HTTPS_CATALOG’, ‘/’);
We need to modify the part:
define(’DIR_FS_ADMIN’, '/home/mystore.com/www/public/admin/');
define(’DIR_FS_CATALOG’, '/home/mystore.com/www/public/');
B- Find the Zen Cart / admin / directory，
The directory name in accordance admin / includes / configure.php defined in amended accordingly。
4. Remove unused administrator accounts
Management page -> Tools -> Manage Settings
In the management page，Open the Tools menu，Select Management Settings
– Check that all administrator accounts are not using and delete。Particular attention to whether there is "Demo" account。
5. Strengthening the administrator password
Be sure to use a certain intensity、Not easy to guess password。
To change the administrator password，Enter the management page -> Tools -> Manage Settings，Click the "Reset Password" button，Or click on the icon would like recycling bins。International trade payment qq 1274899661
We recommend using a password of at least eight。
Password should contain letters、digital、meets the、And capitalization, etc.。
6. Protected content "custom page" "html_includes" in
Well defined your custom page after，(Management page -> Tools -> Edit Page), You want to protect these files:
A. Backup using FTP software download，These files are located
/includes/languages/schinese/html_includes目录。
B. Modify the file CHMOD 644 or 444 (Under Windows or "read-only")。See description above CHMOD
/includes/languages/schinese/html_includes
