Warning: mysql_connect() [function.mysql-connect]: Access denied for user ‘linuxnoo’@'localhost’ (using password: YES) in /tmp/cpanel_phpengine.1304688239.24500MvupN_eQWd on line 1642
Access denied for user ‘linuxnoo’@'localhost’ (using password: YES)

This issue is caused by a mismatch in the cPanel password and the MySQL users password. You can verify this in SSH by running the following.

mysql> use mysql;
mysql> select user,password,password('YourPassword') from user where user='YourCpanelUser';
+----------+-----------------------------+-----------------------+
| user     | password  | password('--')          |
+----------+-----------------------------+-----------------------+
| linuxnoo | *E6.....3F | *B6.....3A |
+----------+-----------------------------+-----------------------+
2 rows in set (0.00 sec)

As you can see above, the two password fields do not match so we need to update this.

mysql> update user set password=password('bNEQL13dvJ') where user='linuxnoo' limit 2;
mysql> select user,password,password('bNEQL13dvJ') from user where user='linuxnoo';
+----------+-------------------------------------------+-------------------------------------------+
| user     | password                                  | password('bNEQL13dvJ')                    |
+----------+-------------------------------------------+-------------------------------------------+
| linuxnoo | *E6D911C8973EEDDA0CE0618EFB493E704776DB3F | *E6D911C8973EEDDA0CE0618EFB493E704776DB3F |
+----------+-------------------------------------------+-------------------------------------------+
2 rows in set (0.00 sec)

After the password update try to install again and it should work just fine.

root@grumpy [/]# cd /usr/local/src
root@grumpy [/usr/local/src]# wget http://nginxcp.com/latest/nginxadmin.tar
root@grumpy [/usr/local/src]# tar xf nginxadmin.tar
root@grumpy [/usr/local/src]# cd publicnginx
root@grumpy [/usr/local/src/publicnginx]# ./nginxinstaller install

The uninstall is just as simple.

root@grumpy [/]# cd /usr/local/src
root@grumpy [/usr/local/src]# wget http://nginxcp.com/latest/nginxadmin.tar
root@grumpy [/usr/local/src]# tar xf nginxadmin.tar
root@grumpy [/usr/local/src]# cd publicnginx
root@grumpy [/usr/local/src/publicnginx]# ./nginxinstaller uninstall

Unfortunately things didn’t go smooth on the first install, and I ran into a few errors which were caused by an out of date python install.

root@grumpy [/usr/local/src]# tar xf nginxadmin2.6-stable.tar
root@grumpy [/usr/local/src]# cd publicnginx
root@grumpy [/usr/local/src/publicnginx]# ./nginxinstaller install

To fix this error, you need to do the following.

remove nginx (instructions at the bottom of the post)
root@grumpy [/usr/local/src]# wget http://www.python.org/ftp/python/2.5.2/Python-2.5.2.tgz
root@grumpy [/usr/local/src]# tar fxz Python-2.5.2.tgz
root@grumpy [/usr/local/src]# cd Python-2.5.2
root@grumpy [/usr/local/src]# ./configure
root@grumpy [/usr/local/src]# make
root@grumpy [/usr/local/src]# make install
root@grumpy [/usr/local/src]# fresh install

Nearly everything that you can do in the WHM backend can be performed via command line.  These scripts are located in your server’s /scripts/ directory.  Only use scripts that have been verified by cPanel, or that you know yourself are safe as an unsafe script may damage your server.

Long list of scripts after the break…

If I remember correctly, the install takes 25-30 minutes to complete depending on your server setup.

Internal Server Error

User ‘useraccount’ is over quota.

This happens when the users ‘overquota’ status is cached and can be fixed by removing the users folder located at the following.

/var/cpanel/overquota/username

Note: Cannot open TUN/TAP dev /dev/net/tun: Permission denied (errno=13)
Note: Attempting fallback to kernel 2.2 TUN/TAP interface
Cannot open TUN/TAP dev /dev/tun0: No such file or directory (errno=2)

I’ve never run into this issue before, but was able to find an awesome tutorial on the OpenVZ website.

First, make sure the tun module has been already loaded on the hardware node:

# lsmod | grep tun

If it is not there, use the following command to load tun module:

# modprobe tun

To make sure that tun module will be automatically loaded on every reboot you can also add it or into /etc/modules.conf (on RHEL see /etc/sysconfig/modules/ directory) or into /etc/sysconfig/vz-scripts/VEID.mount.

echo 'modprobe tun' /etc/sysconfig/vz-scripts/VEID.mount

Allow your container to use the tun/tap device by running the following commands on the host node:

vzctl set VEID --devices c:10:200:rw --save
vzctl set VEID --capability net_admin:on --save

And create the character device file inside the container (execute the following on the host node):

vzctl exec VEID mkdir -p /dev/net
vzctl exec VEID mknod /dev/net/tun c 10 200
vzctl exec VEID chmod 600 /dev/net/tun

Enter cat /dev/net/tun to test whether the TUN/TAP device is available:

• If you receive the message cat: /dev/net/tun: File descriptor in bad state your TUN/TAP device is ready for use.
• If you receive the message cat: /dev/net/tun: No such device the TUN/TAP device was not successfully created.
