The error faced when compiling PHP module to Apache2.

Sorry, I cannot run apxs.  Possible reasons follow:

1. Perl is not installed
2. apxs was not found. Try to pass the path using –with-apxs2=/path/to/apxs
3. Apache was not built using –enable-so (the apxs usage page is displayed)

The output of /usr/local/apache/bin/apxs follows:
./configure: /usr/local/apache/bin/apxs: /replace/with/path/to/perl/interpreter: bad interpreter: No such file or directory
configure: error: Aborting

Replace first line of /usr/local/apache/bin/apxs from,

#!/replace/with/path/to/perl/interpreter

with

#!/usr/bin/perl -w

First of all, lets understand and differentiate some of the /etc/rc[0-6].d .

rc1.d >>> Single user mode

rc2.d >>> Custom user mode

rc3.d >>>Multiple user mode with networking availability

rc4.d >>> Custom user mode

rc5.d >>> Multiple user mode with networking availability that has GUI mode (xlogin)

Now, mysqld service was set to off for rc3.d . We are going to On it in rc3.d level with below command.

# chkconfig –levels 3 mysqld on

Will see S64mysqld in /etc/rc3.d in my case. I see K36mysqld when levels 3 was off in my case.

Add user:

# useradd ftpuser

Check user:

# less /etc/passwd

ftpuser:x:500:500::/home/ftpuser:/bin/bash

Add group:

# groupadd ftpgroup

Check group:

# less /etc/group

ftpgroup:x:500:

Assign user to group:

# vi /etc/group

change ftpgroup:x:500: to ftpgroup:x:500:ftpuser

Install pureftp:

1. Download pureftp installation file from ftp://ftp.pureftpd.org/pub/pure-ftpd/releases/ .
2. Extract the installation file at any directory.
3. Run ./configure –with-everything –with-paranoidmsg –without-capabilities -with-virtualchroot
4. Run make & make install
5. Done

Copy pureftp configuration to /etc :

# cp pure-ftpd-1.0.21/configuration-file/pure-ftpd.conf /etc

Copy pureftp startup script to /usr/local/sbin/ :

# cp pure-ftpd-1.0.21/configuration-file/pure-config.pl /usr/local/sbin/

Create a ftp user :

# pure-pw useradd test -u ftpuser -d /home/directoryname

• useradd > option of pure-pw
• test > the ftp username
• -u > linux username
• ftpuser > the linux user that created
• -d > path to the upload directory
• /home/directoryname > path name

Show ftp user detail :

# pure-pw show test

Output :

Login              : test
Password           : $1$h8ZLTun0$iYCeCgrYfMz0BrbLC/6Ca1
UID                : 500 (ftpuser)
GID                : 500 (ftpgroup)

Allowed local  IPs :

Time restrictions  : 0000-0000 (unlimited)
Max sim sessions   : 0 (unlimited)

Check ftp user option :

# pure-pw usermod test -h

Ftp user option normally stored in /etc/pureftpd.passwd . You will something like below when open this file.

test:$1$vrb6.MK0$/shIogHo4RVvQXr8bJSBe/:500:500::/home/directory/::::::::::::

Generate ftp database :

# pure-pw mkdb

The ftp database file will be created at /etc and named pureftpd.pdb .

Un-comment PureDB & AltLog varialble that store in /etc/pure-ftpd.conf .

Now, we can start the ftp service

# /usr/local/sbin/pure-config.pl /etc/pure-ftpd.conf

Done !!! Pureftp is installed. May try to connect to the ftp service via ftp client or ftp command.

/usr/sbin/setenforce 0

root@servername [~]# service httpd start

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

Unable to open logs

Lets run the netstat to check the Apache process is hook up with which other process.

root@servername [~]# netstat -lnp | grep ’0.0.0.0:80′

tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      22666/exim

Next, run the ps command to check above listening process

root@servername [~]# ps 22666

PID TTY      STAT   TIME COMMAND

22666 ?        S<s    0:00 /usr/sbin/exim -Mc 1L5ryZ-0005tZ-T0

GotYa. Is confirmed that Apache process could not stop due to Exim process.

Run the service reboot command to Exim service. Give a shoot by restarting Exim and then start Apache will wake up your Apache service.

Note : This is an example situation which it does not really relates to Exim process. It could be other process. Do check with netstat command and you will find out.

Above path is actually the Jailshell configuration path created by WHM when a Cpanel user was granted with shell access.

Note : Do not delete any data inside /home/virtfs/Cpanelusername as it can screw up your Cpanel server.

Reason : The /home/virtfs/ is created for user with Jailshell. Virtfs is hardlinked to some system files. By delete the data inside /home/virtfs/, you delete the actual system file they’re linked to. This is going to be bad and screw up your system file and delete other important data such as Mysql database. So, beware on this.
Shall you need to remove any shell access from any cpanel user, just navigate to WHM >> Manage Shell Access and disable Jailed Shell for users.

For your information, when we check the disk size for /home/virtfs/Cpanelusername. You will see some disk size. Imagine if there is few more cpanel user granted with Jailshell, there will few more directories create at /home/virtfs/. You will find there is more disk space after du -sh those directories. But don’t worry as it will not consume your actual server diskspace. Some advice which is /home/virtfs need to excluded from backup system.

Additionally, always be careful when run command ‘rm -rf *’. It will delete all the file with option of recursive and force. Need more information, visit here.

Hope this sharing could help someone to avoid causing error.

However, there will never have one time success installation for a beginner. LOL. Hence, there got few starting erros encounter with the solving steps I locate.

Got this when compile apache,

configure: error: Cannot use an external APR-util with the bundled APR

which can resolve by below configure

# ./configure –enable-so –with-included-apr
# make
# make install
or
# ./configure –prefix=/usr/local/apache2 –enable-so –with-included-apr

Use command to start apache:

# /usr/local/apache2/bin/apachectl start

Remember to edit ServerName under /usr/local/apache2/conf/httpd.conf else below error will display when start apache:

apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName

Then, verify by browse http://localhost/ or http://127.0.0.1/.

*** Drop me any comment if there is any step left and best configure setting to recommend.
