nginx: [error] CreateFile() “D:\nginx-1.20.1/logs/nginx.pid“ failed (2: The system cannot find the

 

After downloading and decompressing nginx, double-click nginx Exe post access http://127.0.0.1/ , the welcome interface can appear

However, when the nginx service is closed on the command line (nginx – s quit), an error is reported: nginx: [error] createfile() “D: \ nginx-1.20.1/logs/nginx. PID” failed

According to the error message, nginx cannot be found in the logs file under the nginx installation directory PID file, check the corresponding file and find that there is no such file

 

 

Solution:
force the nginx process to close in the task manager,

 

 

Then restart with the start nginx command on the command line,

 

 

Now I find that nginx.com appears in the logs file under the nginx installation directory PID file,

 

 

Then use the command nginx – s quit to close the nginx process normally,

 

 

Cannot access at this time http://127.0.0.1/ , nginx was successfully closed

Cause analysis:
to kill the previous nginx process when nginx is started or restarted, you need to go through nginx PID to find the original process, and nginx PID stores the original process ID. Without the process ID, the system cannot find the original nginx process and cannot shut down naturally

After the test, either double-click nginx If nginx is started by exe or CMD command, nginx will be automatically configured under the logs file PID files can be closed normally. I don’t know why I can’t do it the first time
 

[Solved] linux configure: error: no acceptable C compiler found in $PATH

preface

When installing PgSQL on linux, execute /Configure -- prefix =/usr/local/PgSQL error, the same as the following:

configure: error: in `/root/postgresql-14.1':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details

The reason for the error here is that we can’t find a suitable C compiler. We need to update GCC

./Configure is used to detect the target characteristics of your installation platform. This step is used to generate makefile to prepare for the next compilation. – prefix = is the specified software installation directory. You can set the configuration files of some software by specifying the – sys config = parameter. Some software can also add parameters such as – with, – enable , – without, – disable to control compilation. You can allow /Configure – help View detailed help instructions.

Solution:

Centos

 yum install gcc

Ubuntu

apt-get install gcc

[Solved] RocketMQ nameserver startup error: Error: Could not create the Java Virtual Machine.

1. Reasons for error reporting

/usr/local/rocketmq/bin/runserver.sh: 70: [[: not found
Unrecognized option: -Xlog:gc*:file=/dev/shm/rmq_srv_gc_%p_%t.log:time,tags:filecount=5,filesize=30M
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

2. Solution:

Use vim to edit the runserver.sh file in  Edit/usr/local/rocketmq/bin/

3. Error reason

Since the java version installed on the machine is 1.8
But there is an error of unknown reason in the java version judgment on line 70 in the /usr/local/rocketmq/bin/runserver.sh file
This led to the execution of the java 9+ version of the command
Therefore, you only need to comment the judgment and commands of the java 9+ version.

And vice versa, if the java version installed on the machine is 11
Then only need to comment the judgments and commands of the java 1.8 version

When I was running the wordcount instance that comes with the Hadoop cluster, the error message was that the input path did not exist. I searched the Internet for a long time and did not solve it. Finally, I found that the log.1 I created was created locally and was not uploaded. To the hdfs cluster, so an error will be reported when running, the solution is: execute the command:
[root@master ~]# hadoop fs -put log.1/ # (upload the log.1 file to the / directory)
After the operation, you can run the command again:
[root@master ~]# hadoop jar /export/servers/hadoop/hadoop-2.7.3/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.3.jar wordcount /1.log /result
