linux share anti complaints server

A morning to get a customer reflects a lack of space，He said that the space I use www， In fact, very few of，But 50G space almost full：

Filesystem Size Used Avail Use% Mounted on
/dev/simfs 50G 47G 3.1G 94% /

Official statement：

Every day, if the log file’s size is larger than 50MB, they are moved into the client’s home directory. If you set the remove_processed_logs as true, then instead of moving, they will be deleted. Your main statistics calculation will not be affected at all.

In Kloxo / Lxadmin add a domain name,The default is to open the site statistics. When you add the domain name is recommended to turn off this feature。If you do not shut down and traffic statistics lot,Before long the hard drive will be explode statistics file。If your MySQL does not start，It is likely to be the reason。You can turn off the lower position shown in FIG Statistics

To prevent this from happening，Please make the following settings：

ssh login vps，Delete the existing statistics file
Enter the command：
rm -f /home/admin/__processed_stats/*

If the hard disk has been filled and the database can not be started，lxadmin not open，You can log on to perform the removal operation of the system with SSH，command：
rm -f /home/admin/__processed_stats/*
After the deleting start MySQL，command：
service mysqld start

After avoiding also generates more log，It recommended that each domain name do the following settings：

A customer's process：

Customers reflect kloxo can not enter the background，And all the open site。To check，You can ping，Can ssh。Nor restart kloxo。strange。So a look df，Space is full。Following treatment：

[[email protected] __processed_stats]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/simfs 20G 20G 0 100% /
[[email protected] __processed_stats]# pwd
/home/admin/__processed_stats
[[email protected] __processed_stats]# -m -s .
19426 . Logs take up 19G
[root@vps76 __processed_stats]# rm -f /home/admin/__processed_stats/*

Restart kloxo

kloxo service restart

If your login kloxo background，Tip Alert: not_in_list_of_allowed_ip，This is most likely you are not careful to set up IP restrictions，For example whitelist blacklist，He refused to give himself up outside。 How to do?

Log in as root ssh，carried out：
/script/clearallowedblockedip –class=client –name=admin
See the following prompt：

AllowedIp Sucessfully cleared for client:admin
Says admin unblocked，This time you can log in normally kloxo，Be careful not to put themselves in refused。

Forget Kloxo the admin login password how to restore your password? Only reinstall it? Too painful。

Do not worry，There is a way，ssh root user login，Run the following command to reset the admin password：

cd /usr/local/lxlabs/kloxo/httpdocs;lphp.exe ../bin/common/resetpassword.php master ctohome the above command kloxo new password reset for ctohome

then，Your background can log kloxo。After logging，Change your password。

Although the default is not turned xcache kloxo，But sometimes not careful on the，Unknowingly opened xcache。If it turns xcache，lighttpd 500 error please try to close xcache。

If not enough，Fastcgi try again Close。

Not enough，You can also try adding a few more lighttpd process method：In LIGHTTPD.CONF which added：

server.max-worker = 6

# max-connections == max-fds/2 (maybe /3)
server.max-connections = 1024
server.max-fds = 2048

#Maximum number of seconds until an idling keep-alive connection is dropped.
server.max-keep-alive-idle = 5
server.max-keep-alive-requests = 1000

Since the vast majority of Chinese pages when encoding is gb2312, so we kloxo panel installation，The default encoding of apache changed gb2312 (Simplified Chinese)，If your program / web page is the default encoding of UTF-8，Then please switch to lighttpd，Such acquiescence is to support UTF-8 encoding。

kloxo panel switched to apache lighttpd method：

Login kloxo background，Click on the left server：linux => switching program => Select lighttpd and djbdns => Click update => Wait 10 seconds to refresh your page to see results。

If the page does not open，Probably lighttpd does not start，Please start：

Restart Lighttpd，As shown below，In server：linux = "Services =" Click lighttpd this line of three blue dots (I've added a shadow)

How to set up a directory，And let him inside all the attributes are changed to 777 (written permission)? Lxadmin file manager with authority to modify the directory (including sub) method follows FIG.，Remember to Change Permssion Recursively check to make all the subdirectories and files can also change the attributes：

Installed KLOXO，The default is apache web server，Sometimes you may wonder：KLOXO Why UTF-8 / GBK / GB2312 Chinese web pages garbled? This is due to the encoding output set would be forced apache UTF-8 or caused GBK，And your web pages are not in the coding，So there will be problems Chinese garbled。

How to solve the problem? simplest，It is switched to Lighttpd web service software。

apache kloxo panel switched to a method for lighttpd：Kloxo into the background = "server：linux => = handover procedure "Choose lighttpd =" update point。As shown below：

If you want to use apache，We need to find the apache httpd.conf，Modify the default encoding settings，as follows：

First landing VPS with SSH，Modify the httpd.conf file

cd /etc/httpd/conf/
vi httpd.conf

Seek：AddDefaultCharset
The：AddDefaultCharset UTF8
Changed：AddDefaultCharset OFF

In this case，When it will open the page in accordance with encoding settings page to open the page。

Enter the following command to restart Apache
service httpd restart

Use KLOXO panel，FTP connection timeout，Sometimes you can FTP，Sometimes I can not upload，what happened? This is most likely because Lxguard function caused kloxo panel. Solution： Guard Lx disable or whitelist (not fixed due to the total IP's ADLS，IP whitelist setting is not very good)：

Lxguard Profile：Lx guards(Lxguard)The effect is to prevent brute force ssh and ftp。When someone tries to enumerate password ftp or ssh，After the cumulative number of errors，It will be blacklisted。This feature can not be disabled，But you can adjust the allowed number of failed logins or white list。

Prohibited FTP link IP example of Figure (number of failures exceeds a predetermined 21 times，The future will no longer be linked)：

Solution： Disable Lx guards

Kloxo / lxadmin panel is not supported by default mbstrin，And other functions are not supported mb_substr。How to do? How to install mbstring?

Usually you the domain name resolves to the ip of installed kloxo，You see the following kloxo default page。Why does it always displays the default page of kloxo? Usually several reasons，The following very clearly written in English。If you kloxo background has opened this site (bind this domain)，Then need to restart apache / lighttpd take effect after the。If the restart does not work，It would need to verify the correct corresponding IP。

This is the Kloxo Default Page

If you are seeing this page, it means that web has not been configured for this domain on this server.

This could be due to the following causes:

•Kloxo has not restarted the web server yet after you added the domain. Please wait for the web server to restart.
•The domain is pointing to the wrong Kloxo server. Ping the domain and make sure that the IP matches one of the IPaddress seen in admin home -> ipaddresses
•If you are seeing this page when you try to access an IP like http://192.168.1.1, then that means that the IP has not yet been mapped to a domain. Go to client home -> ipaddresses -> ipaddress home -> domain config and map an IP to a domain.
•Once you map an IP to a domain, then you have to make sure that the domain pings back to the same IP. Otherwise, if you try to access the domain, you will get this page. So IP -> domain.com should mean that domain.com pings to the same IP.

How to add IP addresses to the server via kloxo panel? default，If your server has multiple IP addresses，As long as the card is similar to the configuration file ifcfg-eth0:1，ifcfg-eth0:2 format，kloxo can identify multiple default ip address。But if you do not have to modify the configuration file bind IP address，or，IP addresses are added to the batch with the ifcfg-eth0-range0 format，So kloxo could not identify them，This can cause a range of problems,For example, the site always appears not display properly，Always display the default page kloxo。

How kloxo configuration and binding multiple IP addresses? See below：

The following IP and subnet mask，You can not be wrong

If prompted Alert: ipaddress_already_configured，Description IP has been bound over。

If prompted some other host uses this ip that you might have something like this ifcfg-eth0-range0 card configuration file conflict，He needs to be deleted，And service network restart release already bound IP，Then try again。
