wget Error: ERROR: cannot verify nih.at’s certificate, issued by “/C=US/O=Let‘s Encrypt/CN=R3”

Error Message:

--2022-06-20 16:06:37--  https://nih.at/libzip/libzip-1.2.0.tar.gz
Resolving nih.at... 5.2.73.210, 2a04:52c0:101:2e6::de6c
Connecting to nih.at|5.2.73.210|:443... connected.
ERROR: cannot verify nih.at’s certificate, issued by “/C=US/O=Let's Encrypt/CN=R3”:
  Issued certificate has expired.
To connect to nih.at insecurely, use ‘--no-check-certificate’

 

Solution:

Step 1:
It is recommended to run this command first (if it reports an error you can skip it and try running step 2 directly).

sudo yum install -y ca-certificates

Step 2:
Replace the previous wget https://xxxxx command with the following command, –no-check-certificate is the last line of the error message
wget –no-check-certificate https://xxxxx

Perfect solution

Mybatis imported JDBC dependency conflicts with Clickhouse-JDBC dependency.

Solution: Comment out the SpringBoot imported dependencies

            <artifactId>spring-boot-starter-data-jdbc</artifactId>

[Solved] PHP Error: Warning: file_get_contents(): Failed to enable crypto

I. Description
file_get_contents() error when reading https content

II. Reason
Local service is not configured ssl certificate, can not get the contents of the path to https

III. Solution
1, Linux server configuration https ssl certificate.
Linux server configuration https ssl certificate.
2. curl_ request to obtain the content (see the following method curlGet ())

    /**
     * get the content
     * @param $url
     * @return bool|string
     */
    function curlGet($url)
    {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36');
        curl_setopt($ch, CURLOPT_TIMEOUT, 30);
        $content = curl_exec($ch);
        curl_close($ch);
        return ($content);
    }

3.Use file_get_contents() function to skip https authentication

        $streamOpts = [
            'ssl' => [
                'verify_peer' => false,
                'verify_peer_name' => false
            ]
        ];
        $html = file_get_contents($pageUrl, false, stream_context_create($streamOpts));

[Solved] org.springframework.context.ApplicationContextException: Failed to start bean ‘org.springframework.a

Error

org.springframework .context.ApplicationContextException: Failed to start bean &#39 ;org.springframework.amqp.rabbit.config.internalRabbitListenerEndpointRegistry'; nested exception is org.springframework.amqp.AmqpIllegalStateException: Fatal exception on listener startup

Errors reported when using RabbitMq to test switches and queues

Think hard

At first I thought it was the queue’s listener configuration information and listener code that were written wrong，I checked it repeatedly and there was no error.
Then continue to read the error ，there are these two errors，instant epiphany.

Caused by: org.springframework.amqp.AmqpIllegalStateException: Fatal exception on listener startup
Caused by: org.springframework.amqp. AmqpAuthenticationException: com. rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED

Suddenly realized

ACCESS_REFUSEDSuch a big word, I read it several times, but I didn’t expect this error, It is probably the wrong copy when configuring the password

spring:
  rabbitmq:
    host: 192.168.149.128
    port: 5672
    virtual-host: /hotel
    username: hotel
    password: hotel

hotel was resolutely written as guest

Ok, change the password, successfully run, also warn everyone to be careful！！！

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Just check the nacos port and change it to the port used by the project you are running.
