Typo3 won't connect to mysql - mysql

Question

Just installed Typo3 Version 6, Government package on Linux Mint 14. Installed latest version of PHP & MYSQL. Compiled PHP with:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --with-openssl --with-zlib --enable-soap --enable-hash --with-pcre-regex --with-curl --with-gd --with-mysqlih-mysql --with-openssl --with-zlib --enable-soap
make
make install
Typo3 installer gives the following error:
There is no connection to the database!
(Username: typo3, Host: localhost, Using Password: YES)
Go to Step 1 and enter a valid username and password!
The username and password that I entered are correct. I am able to connect to mysql using these credentials with
phpMyAdmin web interface
mysql -u typo3 -p typo3db
Did Google search and found some people had this problem and the cause was one of the three things:
underscore in DB name - as up can see by my db name, it doesn't apply to my case
config not allowing persistent connections to mysql - doesn't apply to my case,since I am currently allowing persistent connections.
permissions of typo3 files - suggested fix was set all files to 755 or 777 (way to permissive in my opinion), but I tried this to rule out permission issue. Didn't resolve the issue in my case.
I enabled general logging for mysql. When I enter username and password for mysql user in the typo3 installer, it immediately gives the error that it can't connect, but mysql logs show no login attempt. Conversely, when I login with phpMyAdmin it does show the success and when I type in a wrong password on purpose, the log shows it is being denied.
This all implies to me that no connection from Typo3 to mysql is being initiated, but I don't now why.
Any thoughts on what the issue could be or what I should check next?

Answer 1

I had a similar issue, but found I had to use the server IP address and not localhost. Odd that localhost has always worked in the past without issue.

Answer 2

I had the exact same problem.
Fixed it by enabling required modules in PHP.
They are listed in the INSTALL.txt file in the root TYPO3 folder.
- fileinfo
- filter
- GD2
- JSON
- mysqli
- openssl
- pcre
- session
- SOAP
- SPL
- standard
- xml
- zlib
I believe the crucial module in this case was mysqli.

Answer 3

My solution is this:
The file access rights to /var/lib/mysql must be set in this manner:
[root#localhost phpmyadmin]# cd /var/lib
[root#localhost lib]# chmod 755 mysql
[root#localhost lib]# ls -ld mysql
drwxr-xr-x 16 mysql mysql 4096 Dez 16 20:14 mysql/
The mysql user and mysql group must be set also in all files and folders under /var/lib/mysql.
After this change I could login to the TYPO3 database using the Install Tool.

Answer 4

I had the same symptom with typo3 4.6, its installer didn't connect. I traced this down to this callstack:
class.ux_t3lib_db.php / sql_pconnect / handler_init
The handler_init function has this code:
if (!$cfgArray['config']['database']) {
// Configuration is incomplete
return;
}
The database property was empty. I had to set it in the localconf.php with this line $typo_db = "mydatabasename";
I also created my database with this name in MySQL.

Answer 5

marc_s,
Did you check your files permissions ?
For TYPO3 I use these command from TYPO3 installation folder :
find . -type d ! -name .svn -exec chmod 755 {} \; && find . -type f ! -name .svn -exec chmod 644 {} \;
chmod -R g+wX fileadmin typo3temp typo3conf uploads
