Background: Converted from EasyApache3 -> EasyApache4 (Cpanel). Went from mpm-prefork/php5.5/dso to mpm-worker/php71fpm/fastcgi.
The error message is:
Failed to parse address "127.0.0.1:3306:3306" in /home/user/conndb/conndb.php on line 2
The code is:
<?php
$con = mysqli_connect('127.0.0.1:3306','user','password','database');
?>
I had done a previous test of this configuration on a test server with no issues - so puzzled that I ran into this in production. Tried changing to localhost but no difference. Had to revert back to EasyApache3 config.
I'm stumped. Notice the port is repeated twice in the error message. I wonder if this version of mysqli is 'smart' enough to know to put in 3306 itself and then chokes when it's explicitly coded?
Closing the question.... confirmed that removing the :3306 port corrected the issue. Obviously a change php5.5 to php7.1. I'm not sure how you'd deal with a non-standard mysql port - but not an issue for me.
According to PHP documentation if using non-standard port you must pass it as a fifth parameter -
// change the last parameter to whatever your DB port is
$con = mysqli_connect('127.0.0.1' 'username', 'password', 'database', 3306);
And by "non-standard port" is meant everything, different by the result of
echo ini_get("mysqli.default_port");
because this is the default value of this parameter.

We changed the configuration of our WebLogic servers to use HTTPS and T3S for connections and use the secure encrypted port 9002 instead of cleartext port 7001. However when using the Web Logic Scripting Tool (WLST)'s connect() function, errors are thrown. One such error is as follows:
WLSTException: Error occurred while performing connect : Cannot connect via t3s or https. If using demo certs, verify that the -Dweblogic.security.TrustKeyStore=DemoTrust system property is set. : t3s://DatServer:9002: Destination 10.10.100.3, 9002 unreachable; nested exception is:
javax.net.ssl.SSLHandshakeException: General SSLEngine problem; No available router to destination
Use dumpStack() to view the full stacktrace :
The syntax of the connect function is: connect('user', 'password', 't3s://host:9002')
This connect() function works fine before the switch from HTTP to HTTPS. Now we cannot connect to the remote admin server using the connect command. Does anyone have any idea how to fix this?
I read some interesting help options but none of them seemed to work. These help suggestions and tips are located here: https://community.oracle.com/thread/1036828
We were able to connect to the remote host and port via telnet. We saw that the port is open and listening for connections on the loop back address with netstat. We tried adding these options to the script invocation: java -cp /path/to/weblogic.jar weblogic.WLST -Dweblogic.security.TrustKeyStore=DemoTrust -Dssl.debug=true Dweblogic.security.SSL.ignoreHostnameVerification=true -Djava.security.egd=file:/dev/./urandom but this also did not work.
We enabled tunneling in the General tab of WebLogic but not in the HTTP tab. I am not the one in control of the server so I just have to suggest things and hope that the instructions are followed.
I get it running in 12.2. by adding to
../oracle_common/common/bin/setWlstEnv_internal.sh
at the end the following lines (youu need to customize line 5 und 6, the values in brackets):
JAVA_OPTIONS="-Dweblogic.ssl.JSSEEnabled=true ${JAVA_OPTIONS}"
JAVA_OPTIONS="-Dweblogic.security.SSL.enableJSSE="true" ${JAVA_OPTIONS}"
JAVA_OPTIONS="-Dweblogic.security.SSL.ignoreHostnameVerification=true ${JAVA_OPTIONS}"
JAVA_OPTIONS="-Dweblogic.security.TrustKeyStore=CustomTrust ${JAVA_OPTIONS}"
JAVA_OPTIONS="-Dweblogic.security.CustomTrustKeyStoreFileName= ${JAVA_OPTIONS}"
JAVA_OPTIONS="-Dweblogic.security.CustomTrustKeyStorePassPhrase= ${JAVA_OPTIONS}"
JAVA_OPTIONS="-Dweblogic.security.CustomTrustKeyStoreType=JKS ${JAVA_OPTIONS}"
export JAVA_OPTIONS
and modifying in
../oracle_common/common/bin/wlst_internal.sh
the line starting with
eval '"${JAVA_HOME}/bin/java"' ${JVM_ARGS} ...
by adding ${JAVA_OPTIONS}
so that it looks as follows:
eval '"${JAVA_HOME}/bin/java"' ${JVM_ARGS} ${JAVA_OPTIONS} weblogic.WLST '"$#"'
Hope this helps, allthough modifying scripts that are named "..internal.." doesn´t give me a good feeling
export this before running wlst.sh
export WLST_PROPERTIES=" -Dweblogic.security.TrustKeyStore=CustomTrust -Dweblogic.security.CustomTrustKeyStoreFileName=/u01/oracle/properties/truststore.jks -Dweblogic.security.CustomTrustKeyStoreType=jks -Dweblogic.security.CustomTrustKeyStorePassPhrase=qaz#1234 " ;
I have gone through number of threads on stackoverflow and on other forums to find the answer but could not find relevant answer. People have applied different approaches but none has worked for me thus far.
I am using CI 3 on XAMPP and whenever I load database library in the model, I run into 500 Error.
Here is my CI database config info:
'hostname' => 'localhost',
'username' => 'my_user',
'password' => 'my_pass',
'database' => 'prod_db',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
PHP ini db libraries are as below:
extension=php_bz2.dll
extension=php_curl.dll
extension=php_fileinfo.dll
;extension=php_ftp.dll
extension=php_gd2.dll
extension=php_gettext.dll
;extension=php_gmp.dll
;extension=php_intl.dll
;extension=php_imap.dll
;extension=php_interbase.dll
;extension=php_ldap.dll
extension=php_mbstring.dll
extension=php_exif.dll ; Must be after mbstring as it depends on it
extension=php_mysqli.dll
;extension=php_oci8_12c.dll ; Use with Oracle Database 12c Instant Client
;extension=php_openssl.dll
;extension=php_pdo_firebird.dll
extension=php_pdo_mysql.dll
;extension=php_pdo_oci.dll
;extension=php_pdo_odbc.dll
;extension=php_pdo_pgsql.dll
extension=php_pdo_sqlite.dll
;extension=php_pgsql.dll
;extension=php_shmop.dll
; The MIBS data available in the PHP distribution must be installed.
; See http://www.php.net/manual/en/snmp.installation.php
;extension=php_snmp.dll
My model code is as below:
class loginmodel extends CI_Model {
public function validate_login($username, $password) {
$this->load->database();
$var = 0;
return $var;
}
}
Whenever I remove $this->load->database(); from the model, my code runs and i am able to redirect to a "Login Failed" page. BUT, whenever I load my database library in autoload.php or load it in above model, code fails.
Autoload.php
$autoload['libraries'] = array('database');
Apache error logs showed below errors but I could not figure as why this was happening.
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\php\\ext\\php_mysqli.dll' - The specified module could not be found.\r\n in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\\php\\ext\\php_pdo_mysql.dll' - The specified module could not be found.\r\n in Unknown on line 0
Please advise.
EDIT:
I verified all config to be OK and as stated in the comments, I added environment variables to windows and verified through PHPInfo that mysqli and mysqlnd were loaded.
Despite getting all the config right, error still persisted and I did a clean install of CI to reproduce library load failure. This time CI returned an error that db access was denied.
I then realized that after migration, database user was not created in the new environment. So once I created the desired user and assigned it required privileges, I was able to run the code just fine.
Therefore, if anyone encounters such issue in future, below steps might help:
First and foremost, verify if your desired user can access the
database.
Modify your .htaccess to use your desired URL schemes only after
verifying that database connection is working
Then verify that absolute path is available in PHP.ini on XAMPP.
Plus, verify that PHP is added in the environment variables. My
Values on Windows 10 are as follows: Variable Name: PHP , Variable
Value: C:\xampp\php\ext
In CI, mysqli is selected as database driver
In PHP.ini mysqli extension is enabled. i.e. php_mysqli.dll
Echo PHPInfo to verify that mysqli and mysqlnd are available in your
installation.
If nothing works, do a clean install of CI on a separate directory and load database library after setting up your database configuration and before setting up .htaccess until you can reproduce the error.
Hope that error will be eliminated!
While trying to start my Play app locally I am getting a
java.lang.IllegalArgumentException: port out of range:-1
exception followed by a
(*:playRun) java.lang.reflect.InvocationTargetException
message. I can see in the trace the invalid port arg being sent (..../Scala/launcher/sbt-launch.jar" xsbt.boot.Boot "~run -1") but cannot find where to update this argument. There has to be somewhere to override default values. And... No matter what is in the application.conf (http.port) or what I pass on the command line -Dhttp.port I still get the same error. Any info would be enormously appreciated.
I had the same exception and I was in touch with the IntelliJ support team, and got the message it was a bug, because of the https protocol in the open browser field. The url parser cannot handle https and thus not extract the port number.

Hello Ive downloaded jetty and whenever I try to start it it generate the following log and gives an error so I can't use it, can somebody tell me whats wrong or whats missing
Im starting on terminal in the bin folder with the "./jetty.sh start"
Here's the error on localhost:8080
Error 404 - Not Found.
No context on this server matched or handled this request.
Contexts known to this server are:
Powered by Jetty Java Web Server
Heres the log:
https://www.dropbox.com/s/u6j7t1lhqscv34l/log.rtf
Looks like that port 8080 is already in use: "java.net.BindException: Address already in use
"
Try an different port or don't declare a port and use logic like this to figure out what you are bound to:
Server server = new Server(0);
int port = ((ServerConnector) server.getConnectors()[0]).getLocalPort();
The precedence section in chapter 9.3.1 tells me that I should apply the special cases first and then the general ones.
[General]
*.host[0].waitTime = 5ms # specifics come first
*.host[3].waitTime = 6ms
*.host[*].waitTime = 10ms # catch-all comes last
I have following lines in the omnetpp.ini file:
**.server[*].tcpApp[0].port = 1000
**.pods[0..1].**.server[*].tcpApp[0].port = 80
**.pods[2..3].**.server[*].tcpApp[0].port = 21
This code works, but every server has 1000 when checking the parameter and not the special cases 80 and 21. So I want it to look like that:
**.pods[0..1].**.server[*].tcpApp[0].port = 80
**.pods[2..3].**.server[*].tcpApp[0].port = 21
**.server[*].tcpApp[0].port = 1000
Yet, this creates an error, which consists of a null pointer exception in the TCP module of the StandardHost module my server is build on.
In the ned file, the parameter is declared like this:
int port = default(1000); // port number to listen on
Leaving that catch-all line out causes the error too. Only taking the last line above the other two makes it possible to let the simulation run through.
An example for the port parameter can be found in TCPServerHostApp.ned from INET. I want to assign different ports for different services which should run on the servers.
What is your advice for me, to apply those parameters correctly? Is there an error in the way I set the parameters, or do I need to set the ports somewhere during the initialization process myself (which would make no sense to me)?
Edit:
The karma system does not allow me to answer the question yet, so here is the cause of my problem:
Well, the problem was at another place. When connecting a new socket with connect(ipaddr, port), I got the wrong port from the job request message.
At the traffic generation module, I read the wrong port for connection to the server, which caused an error, as the port being used was always the default = 1000 instead of 80 or 21.
The servers expected 80 or 21, causing a crash when the socket tried to connect with port 1000.
Just want to add this here as well, so everybody sees I found the error.
