install VC_redist.x86 You can execute both OK

Input gpedit.msc, Open policy management

After enabling certificate update, it works normally
Because some system images are built earlier , And the system cannot be updated , You need to install a system patch to complete vc++ install

4.Centos Environmental Science rpm initialization MySQL Report errors

Centos7 Provided by default openssl The version is 1.0.2 Of , some php Extensions or other software dependencies 1.1 Above version , If it is too low, an error will be reported
libssl.so.1.1: cannot open shared object file: No such file or directory
There is also implementation openssl version The times error is consistent with the above , This is because openssl The location of the library is incorrect or not installed 1.1 The problem with the above version
Want to upgrade openssl Version needs to be compiled manually , The error reporting solution is very simple , Install correctly ,
Now let's say that I use Centos7 For example , Let's talk about the specific compilation and installation steps

–openssl Version confirmation
[[email protected] ~]# openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013
– compile openssl
tar -xvf openssl-1.1.1g.tar.gz
cd openssl-1.1.1g
./config shared --openssldir=/usr/local/openssl --prefix=/usr/local/openssl
make && make install

– To configure
After compilation , Use openssl version, Let's take a look at the current situation openssl Version number ,
You will find out whether it is 1.0.2, So here we need to do some additional configuration work .
[[email protected] openssl-1.1.1g]# more /etc/ld.so.conf
include ld.so.conf.d/*.conf
[[email protected] openssl-1.1.1g]# echo “/usr/local/lib64/” >> /etc/ld.so.conf
[[email protected] openssl-1.1.1g]# ldconfig
Again using openssl version Just verify the version ,
If it doesn't , Try the following ,
Execute sequentially （ Back up the old version first , Then create a soft connection from the installation location of the new version ）
mv /usr/bin/openssl /usr/bin/openssl.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
echo “/usr/local/openssl/lib” >> /etc/ld.so.conf
ldconfig -v

4.MySQL8 Unable to log in after installation

First method ：

1. Edit with command /etc/my.cnf The configuration file , namely ：vim /etc/my.cnf perhaps vi /etc/my.cnf
2. stay [mysqld] Add below skip-grant-tables, Then save and exit
3. restart mysql service ：service mysqld restart
4. change root user name
After the restart , perform mysql Order to enter mysql Command line
5. modify root User password , Note here , Sometimes it will be reported that modification is not allowed , First flush privileges You can do it again
update mysql.user set authentication_string=password(‘root’) where user=‘root’; --5.7 edition
flush privileges;
6. hold /etc/my.cnf Medium skip-grant-tables Comment out , And then restart mysql, namely ：service mysqld restart
Okay , You can use root New password login ！

The second way ：

stay mysql8 Under the system , The following method is applicable （ The full path ）
G:mysql-8.0.23-winx64inmysqld --datadir=G:mysql-8.0.23-winx64data80323308 --console --skip-grant-tables --shared-memory

Then open another window , Execute the following command
cd G:mysql-8.0.23-winx64in

mysql> select user,host,authentication_string from mysql.user;
mysql> delete from mysql.user where user=‘root’ ;
mysql> flush privileges; -- Remember to refresh , If the prompt cannot be created
mysql> create user [email protected]‘%’ identified with mysql_native_password by ‘root’;
mysql> grant all on . to [email protected]‘%’ with grant option;
mysql> flush privileges;
mysql> drop user ‘root’@‘localhost’;
mysql> flush privileges;
mysql> create user [email protected]‘localhost’ identified with mysql_native_password by ‘root’;
mysql> grant all on . to [email protected]‘localhost’ with grant option;
mysql> flush privileges;
