WinNMP - Advanced usage and Debugging
After adding a new project with a local test domain name like
myprojectname.test you should test in the browser if it is reachable by browsing to
http://myprojectname.test. If it is unreachable you should try the following:
- open Hosts File Editor, and manually add
127.0.0.1 myprojectname.testif missing
- in a Command Prompt Window execute:
- repoen your browser
- your hosts file
c:\Windows\System32\drivers\etc\hostscould be corrupted if you manually edited it and saved it with non-windows newlines
After changing the configuration files, one server like nginx might refuse start. In order to find out the reason, you need to Check Configuration Syntax:
- In the WinNMP Manager window, use the Check Configuration Syntax buttons to see the start up errors for Nginx and MySql
- For PHP, if there are any startup errors, they will be shown as alert messages.
- Also check the server logs in
- To see the commands used to start each service, Kill all servers and restart with
WinNMP.exe --debug( Display debug messages )
- If nothing works, delete that configuration file, or from WinNMP\conf
nginx.conf, mysql.ini, php.ini, kill all servers and restart WinNMP.exe. The Server Manager will copy the default configuration files to WinNMP\conf.
You can safely move the WinNMP stack without loosing any data, projects, databases or settings. Run WinNMP installer once on the new machine, then overwrite/sync the whole WinNMP folder with the cloned one.
For example, syncing your work from
C:\MyWork\WinNMP on Machine1 to
D:\WinNMP on Machine2 should be done by running the installer once on Macine2 (and choosing
D:\WinNMP as destination) then overwriting
D:\WinNMP each time you need to sync your work.
If you move WinNMP stack to a new machine without running the installer, PHP 5.5 and later might refuse to start, because it requires Visual C++ Redistributable for Visual Studio 2012. You can install it manually from here. It will not run on windows XP.
If you upgrade WinNMP and you find that MariaDB dose not start, try the following:
Open a command prompt and enter
Check if the configuration file syntax is correct by pressing the corresponding button in WinNMP Manager
c:\WinNMP\log\mysql.logfor any clues
If you find a line like [ERROR] Table 'mysql.user' doesn't exist , in order to recreate the table, enter in the command prompt window:
mysql_install_db -d c:\WinNMP\data
If your access to the database is denied, kill mysqld and try to repair the privilege tables:
mysqld.exe --defaults-file=c:\WinNMP\conf\mysql.ini --skip-grant-tables mysqlcheck.exe -u root --repair --force --silent --use-frm --databases mysql mysql_upgrade.exe -u root --force
If your access is still denied (root with no password), you could trigger the execution of the commands above plus root password reset by deleting the file
c:\WinNMP\bin\mysql.bat and restartig WinNMP
After you manage to start MariaDB, you could check the integrity of your tables by running
mysqlcheck.exe -u root --all-databases --auto-repair`
If there are still some InnoDB crashed tables, you could try to recover your data:
innodb_force_recovery = 1in
conf\mysql.iniunder [mysqld], start MariaDB, dump all data data with
mysqldump -u root --opt --default-character-set=utf8 --triggers --routines --all-databases > c:\WinNMP\backup\dump.sql, stop MariaDB, remove all data
del /f /s /q c:\WinNMP\data\*, execute
mysql_install_db.exe --datadir=c:\WinNMP\datathen remove
conf\mysql.ini, start MariaDB, then import your data back.
Or you could delete
c:\WinNMP\dataif you don't need to recover any data, and execute the latest installer
Also, don't forget to backup your databases regulary..
Don`t do it! WinNMP needs to perform some maintainance tasks on MariaDB and it needs root access without password. This is no more of a security risk than having a password for WinNMP stored somewhere on the disk or registry.
Let`s say you want to use Nginx 1.2.x instead of the currently installed version, or PHP 5.3.x
