Unable to connect to MKS：Internal error

Question:
Unable to connect to MKS: internal error when opening the window, we managed to log in to the vCenter Server using the VSphere Client to operate the virtual machine on the host. However, when logging in to the ESXi host using the VSphere Client, we were Unable to open the window of the virtual machine.

Problem Solving:
1. Check whether port 902 on the Client host is occupied, and release if occupied.
    
The port is not occupied
2. Turn on the SSH function of ESXi host and log in to ESXi.
3. Execute service mgmt-vmware restart
Note: Some people may execute this command after the service may appear is not recognized command, some people may not find this MGMT-VMware service, this time can try the following method.
4. Vi/etc/vmwaer/config
Add a
Vmauthd. Server. AlwaysProxy = “TRUE”
Test whether the service is available, do not restart the ESXi host, and then try again.

All the above methods are not good, then reinstall the vCenter Server! Good luck.

error: How to solve stray ‘\342’ in program

I copied a relatively simple code from the Internet, and encountered the following problems when compiling:
Test_getopt.c :9:35: error: stray ‘\342’ in program

test_getopt.c:13:4: error: Stray ‘\342’ in program
test_getopt. C :13:4: error: stray ‘\200’ in program
Say, the reason for this problem is that the source code exists in Chinese characters, such as “”,, etc., it can be changed!

Solution to “An error occurred while loading the archive” appears when decompressing the rar file compressed package

The installation
The reason is that the Linux version does not support RAR commercial/non-free formats by default, we just need to install UNrar.
compression

sudo apt-get install rar

Unpack the function

sudo apt-get install unrar

The use of Chinese characters in Qt and the solution to the “error C2001: newline in constant” problem

Problem description: In my program, I want to use the following code to change the prompt in the input field to “Please enter your password”. But the program error, unable to recognize Chinese characters.

QLineEdit *passwordEdit;
passwordEdit->setPlaceholderText("Enter your password please");

solution: use QString::fromLocal8Bit() method to transcode Chinese characters, the program can normally recognize Chinese character QString. Change the above code as follows:

    QString str;
    str=str.fromLocal8Bit("Enter your password please");
    passwordEdit->setPlaceholderText(str);

another problem: program error “error C2001: newline in constant”


Problem analysis: The encoding mode of the code file Login. CPP is not correct. Changing the encoding mode of the file login. CPP to UTF-8 can solve this problem. The method I used to modify the encoding method of the file was to open the CPP file with notepad software and select the encoding form of the file in the “Save as” window:

After saving the file as UTF-8, reload the file and compile the program. The error disappears and the Chinese character can be displayed normally.

Fail to convert to internal representation
The error is that the Hibernate configuration file cannot be converted into information for the corresponding table in the database.
In general, Hibernate field attributes are wrongly written, String type is written as long, number type is written as String and so on, causing the database content cannot be converted to Java class.  

caffe deep learning [three] compilation error: fatal error: hdf5.h: No such file or directory compilation terminated.

Question:
When configuring Caffe-SSD today, I was ready to compile Caffe when I encountered:

fatal error: hdf5.h: No such file or directory compilation terminated.

Such problems are shown in the following figure:

The reason is that the header file for HDF5.h was not found.
 
 
 
 
 
 
Solutions:
1. Modify makefile.config file
Go to the download directory for Caffe
In the makefile.config file, hold down CRTL + F to search: INCLUDE_DIRS
Note that it’s not makefile.config. example!!
Add/usr/include/hdf5/serial/to INCLUDE_DIRS
Namely, the original:

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include

Now it’s:

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/

 
 
2. Modify the Makefile file
In the Makefile file, press and hold CRTL + F to search: LIBRARIES +=
Note that this is not the makefile.config from step 1 above!!
Change HDF5_HL and HDF5 to HDF5_SERIal_HL and HDF5_serial.
Namely, the original:

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5

Now it’s:

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial

The solution

npm install -g mirror-config-china --registry=http://registry.npm.taobao.org
npm install node-sass
yarn install

Solve the problem of shell script “syntax error near unexpected token `fi'”.

Start by listing my shell script.
I edit it in the Windows editor and then upload it to Linux for execution.

#!/bin/bash
Monitor()
{
	pgrep -x mysqld &> /dev/null
	if [ $?-ne 0 ];
	then
		echo "At time: `date` :MySQL is stop .">> /opt/service/logs/mysqlMonitor.log
		/sbin/service mysqld start
	else
		echo "MySQL server is running ."
	fi
	echo "-----------------------------------"
}
Monitor

This error has been reported since Linux was executed.
mysqlmonitor.sh: line 9: syntax error near unexpected token `fi’
mysqlmonitor.sh: line 9: `fi’
At the beginning, I thought the Linux command was wrong. I looked up a lot of information. It was a simple statement, and I was sure it was right. But why report such an error?
I took the cat-v mysqlmonitor.sh command to see my code

Monitor()^M
{^M
        pgrep -x mysqld &> /dev/null^M
        if [ $?-ne 0 ];then^M
                echo "At time: `date` :MySQLM-BM- is stop .">> /opt/service/logs/mysqlMonitor.log^M
                /sbin/service mysqld start^M
        else^M
                echo "MySQL server is running ."^M
        fi^M
        echo "-----------------------------------"^M
}^M
Monitor^M

Found in Linux after the automatic view in the end of the line with ^M identity, through looking up the information that in Windows and Linux is not the same newline. The details can also be confirmed by the command again.
Open the file with Vim and type in command line mode

What we found was DOS

Now set our code mode with the command: set FF = Unix

And then save the code


Look again and discover that the code is programmed for Unix
Cat -v **.sh to see that the code is normal.
There are no errors in executing the code again.
