I am using third party cert.pem file to connect their server in Laravel. In my local machine it is working fine and on digital ocean droplet with centos 7 it is giving error "unable to load client cert: -8018 (sec_error_unknown_pkcs11_error "
Any help appreciated
tried with direct full path and check file exists
After contacting server support, came to know that Centos 7 has a problem with loading client certificate file. We have tried in Rocky Linux and works just fine.
I am using php mysqli_connect for login to a MySQL database (all on localhost)
<?php
//DEFINE ('DB_USER', 'user2');
//DEFINE ('DB_PASSWORD', 'pass2');
DEFINE ('DB_USER', 'user1');
DEFINE ('DB_PASSWORD', 'pass1');
DEFINE ('DB_HOST', '127.0.0.1');
DEFINE ('DB_NAME', 'dbname');
$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
if(!$dbc){
die('error connecting to database');
}
?>
this is the mysql.user table:
MySQL Server ini File:
[mysqld]
# The default authentication plugin to be used when connecting to the server
default_authentication_plugin=caching_sha2_password
#default_authentication_plugin=mysql_native_password
with caching_sha2_password in the MySQL Server ini file, it's not possible at all to login with user1 or user2;
error: mysqli_connect(): The server requested authentication method unknown to the client [caching_sha2_password] in...
with mysql_native_password in the MySQL Server ini file, it's possible to login with user1, but with user2, same error;
how can I login using caching_sha2_password on the mySql Server?
I solve this by SQL command:
ALTER USER 'mysqlUsername'#'localhost' IDENTIFIED WITH mysql_native_password BY 'mysqlUsernamePassword';
which is referenced by https://dev.mysql.com/doc/refman/8.0/en/alter-user.html
if you are creating new user
CREATE USER 'jeffrey'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
which is referenced by https://dev.mysql.com/doc/refman/8.0/en/create-user.html
this works for me
As of PHP 7.4, this is no longer an issue. Support for caching_sha2 authentication method has been added to mysqlnd.
Currently, PHP mysqli extension do not support new caching_sha2 authentication feature.
You have to wait until they release an update.
Check related post from MySQL developers: https://mysqlserverteam.com/upgrading-to-mysql-8-0-default-authentication-plugin-considerations/
They didn't mention PDO, maybe you should try to connect with PDO.
ALTER USER 'mysqlUsername'#'localhost' IDENTIFIED WITH mysql_native_password BY 'mysqlUsernamePassword';
Remove quotes (') after ALTER USER and keep quote (') after mysql_native_password BY
It is working for me also.
If you're on Windows and it's not possible to use caching_sha2_password at all, you can do the following:
rerun the MySQL Installer
select "Reconfigure" next to MySQL Server (the top item)
click "Next" until you get to "Authentication Method"
change "Use Strong Password Encryption for Authentication (RECOMMENDED)" to "Use Legacy Authentication Method (Retain MySQL 5.X Compatibility)
click "Next"
enter your Root Account Password in Accounts and Roles, and click "Check"
click "Next"
keep clicking "Next" until you get to "Apply Configuration"
click "Execute"
The Installer will make all the configuration changes needed for you.
Like many many people, I have had the same problem. Although the user is set to use mysql_native_password, and I can connect from the command line, the only way I could get mysqli() to connect is to add
default-authentication-plugin=mysql_native_password
to the [mysqld] section of, in my setup on ubuntu 19.10, /etc/mysql/mysql.conf.d/mysqld.cnf
It's working for me (PHP 5.6 + PDO / MySQL Server 8.0 / Windows 7 64bits)
Edit the file C:\ProgramData\MySQL\MySQL Server 8.0\my.ini:
default_authentication_plugin=mysql_native_password
Reset MySQL service on Windows, and in the MySQL Shell...
ALTER USER my_user#'%' IDENTIFIED WITH mysql_native_password BY 'password';
I ran the following command
ALTER USER 'root' # 'localhost' identified with mysql_native_password BY 'root123'; in the command line and finally restart MySQL in local services.
If you're on a Mac, here's how to fix it. This is after tons of trial and error. Hope this helps others..
Debugging:
$mysql --verbose --help | grep my.cnf
$ which mysql
/usr/local/bin/mysql
Resolution:
nano /usr/local/etc/my.cnf
Add: default-authentication-plugin=mysql_native_password
-------
# Default Homebrew MySQL server config
[mysqld]
# Only allow connections from localhost
bind-address = 127.0.0.1
default-authentication-plugin=mysql_native_password
------
Finally Run: brew services restart mysql
Now you can upgrade to PHP7.4 and MySQL will go with caching_sha2_password by default, so default MySQL installation will work with mysqli_connect No configuration required.
I tried this in Ubuntu 18.04
and is the only solution that worked for me:
ALTER USER my_user#'%' IDENTIFIED WITH mysql_native_password BY 'password';
If you have not yet already changed your MySQL default authentication plugin, you can do so by:
Log in as root to MySQL
Run the following SQL command:
a. if you are running MySQL in a different server:
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password
BY 'password';
b. if you are running MySQL in a different server:
ALTER USER 'root'#'%' IDENTIFIED WITH mysql_native_password
BY 'password';
I am using laravel 5.8 and having MAMP server got this error resolved by adding DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock in .env file like below
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=dbname
DB_USERNAME=root
DB_PASSWORD=root
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock
In my case when I was using WAMP server I fixed it using following
Note the port in mySQL's "my.ini" file. In my case it was changed to 3308 when I was switching b/w MariaDB and MySQL DB.
Use the port number when you create mysqli object.
Using the above steps I was able to run the program successfully.
phpMyAdmin GUI way
Note: This method may not work if you have the problem with root user account.
Login to phpMyAdmin as root.
Switch to "User Accounts" tab.
Select the username you get error with.
From the top buttons, switch to "Login Information" section.
In "Login Information" box, change "Authentication plugin" from "Caching sha2 authentication" to "Native MySQL authentication". Also, you must fill in other required fields, obviously, including username and password.
Save it by clicking on the "Go" button at the bottom.
Return back to terminal and enjoy. :)
In my case, i'm using PHP Symfony framework and it's a silly mistake.
The database credential was wrong in paramers.yml.
After changing the credentials accordingly the problem was gone.
In Digital Ocean Managed Mysql, we have an option to change encryption, you can change to legacy and it'll work ok.
I think it is not useful to configure the mysql server without caching_sha2_password encryption, we have to find a way to publish, send or obtain secure information through the network. As you see in the code below I dont use variable $db_name, and Im using a user in mysql server with standar configuration password.
Just create a Standar user password and config all privilages. it works, but how i said without segurity.
<?php
$db_name="db";
$mysql_username="root";
$mysql_password="****";
$server_name="localhost";
$conn=mysqli_connect($server_name,$mysql_username,$mysql_password);
if ($conn) {
echo "connetion success";
}
else{
echo mysqli_error($conn);
}
?>
I've got a macOS 10.13 server running, on which I have recently had to change the hostname (upstream IT requirements) - and I suspect this has broken Kerberos.
Changing the hostname appears to have been successful: I exported the Open Directory setup, modified it, and reimported it into the updated setup - user accounts exist, and manual authentication works as expected. changeip is happy:
mac-mini:~ server_admin$ sudo changeip -checkhostname
dirserv:success = "success"
However SSO from client machines does not appear to be successful.
Attempting to run kinit with a valid user account shows this:
mac-mini:~ server_admin$ kinit test#MAC-MINI.EXAMPLE.COM
test#MAC-MINI.EXAMPLE.COM's password:
kinit: krb5_get_init_creds: Server (krbtgt/MAC-MINI.EXAMPLE.COM#MAC-MINI.EXAMPLE.COM) unknown
Looking at /etc/krb5.conf, I only see this:
[libdefaults]
kdc_timeout=5
...which is the same as it was on my previously-working configuration.
And now I'm a bit stumped. All the documentation for destroying and rebuilding Kerberos setups seem to be out of date. Any ideas?!
Thanks.
I use actual version of phpMailer (downloaded yesterday from github). It sends mails from my local computer (Win10, xampp 7.4.3) and can't send it from server (centOs7, nginx, php7). Both computers in one LAN behind the same firewall.
I suspect php.ini configuration, but what should be configured exactly?
Thanks for any help.
The solution:
# sudo setsebool -P httpd_can_sendmail 1
The tracking of my search:
Switch on the DebugMode in phpMailer (for each new PHPMailer object):
$mail = new PHPMailer\PHPMailer\PHPMailer();
$mail->SMTPDebug = 4;
Checking out 'Console' tab output in Chrome DevTools:
SMTP ERROR: Failed to connect to server: Permission denied (13)
Googling for the error text - https://stackoverflow.com/a/50302148/9751142
Hope this helps anybody else.
I can't seem to get the NppFTP plugin to connect to my localhost (via XAMPP) for local development using Notepad++.
According to the http://localhost/xampp/ docs, the default username and password are 'newuser' and 'wampp' accordingly.
I'm using these settings:
host: 127.0.0.1
port: 21
username: newuser
password: wampp
initial remote directory: C:/xampp/htdocs/myrootdirectory
The console just says 'Quit' right after I try and connect.
Anyone know what I'm doing wrong? And if it's because localhost is not a remote directory, how do I configure Notepad++ to browse my local files without relying on Windows Explorer?
If you're running on windows, make sure you're running your xampp control (xampp ui ) as admin. Then, you have yo check SVC checkbox before filezilla then click start. A pop-up will prompt and click Yes to install it as a service.
after that, click admin then click Yes. set you password then you're good to go.
In you're notepadd++, the settings are the same with the one you posted above.
Hope that helps.
Raul
Actually, it doesn't make sense to Filezilla into your localhost, you should just use the Notepad Plugin, Explorer.
