This article will introduce to you how to upgrade the MySQL version of wdCP panel to 5.6. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.
Preface
The main purpose of installing the wdCP panel before was to build a WordPress personal blog. Then I went to the WordPress official website and found that the system required PHP7.3 version. and MySQL5.6 or above.
So, I immediately upgraded the PHP version (very convenient and not troublesome), and then it toHow to upgrade MySQL version to 5.6 in wdCP panel me a long time to upgrade the database (I believe you can read it in this article to my twists). Finally, when the blog I wrote toHow to upgrade MySQL version to 5.6 in wdCP panel a screenshot of the official WordPress website, I found the sentence "But these are not necessary..." and my mentality collapsed.
Server environment
System: CentOS7.7
Panel: wdCP v3.3.9
wdCP built-in database: MySQL 5.5.62
MySQL upgrade steps
In order to reduce the possibility of errors, it is best to enter the following commands into the Linux terminal in copied form. Because the article has an original statement (shameless), you can copy the command to Notepad first, and then copy it into the terminal. In order to facilitate troubleshooting, I also copied some running results.
Because some commands have path problems during the process, I don’t know if I can directly write them into a .sh file and then run them directly. I saw many blogs saying it was possible, but I was skeptical and wouldn’t recommend it for a novice like me to try.

There are many commands in this step, so be sure not to copy and omit them! ! ! At the same time, the waiting time will be relatively long, so you need to maintain a certain amount of patience.
rm -f /www/wdlinux/mysql ln -sf /www/wdlinux/mysql-5.6.How to upgrade MySQL version to 5.6 in wdCP panelHow to upgrade MySQL version to 5.6 in wdCP panel /www/wdlinux/mysql
Note: If you There is a problem with the execution, which means that the copy of make install may have been missed in the previous step (don't ask, it's just me who made a mistake).
The command for this step is executed in the /www/wdlinux/mysql directory, please pay attention to switching.
scripts/mysql_install_db --user=mysql --basedir=/www/wdlinux/mysql --datadir=/www/wdlinux/mysql/data chown -R mysql.mysql /www/wdlinux/mysql/data
This step is quite tricky. It is best to copy the commands step by step! Because after executing the first line of the cp command (you have to press y many times), you will be asked whether to overwrite it, so all the commands you copied later will be gone.
The cp command in lines 3 and How to upgrade MySQL version to 5.6 in wdCP panel needs to be executed in the /www/wdlinux/mysql-5.6.How to upgrade MySQL version to 5.6 in wdCP panelHow to upgrade MySQL version to 5.6 in wdCP panel directory using the cd command. I am talking about my own directory. You can adjust it according to your own situation. (It’s all my fault)
mv /www/wdlinux/mysql/data/mysql /www/wdlinux/mysql/data/mysql1 cp -pR /www/wdlinux/mysql_bk/* /www/wdlinux/mysql/data/ cp support-files/mysql.server /www/wdlinux/init.d/mysqld cp support-files/mysql.server /etc/init.d/mysqld chmod 755 /www/wdlinux/init.d/mysqld chmod 755 /etc/init.d/mysqld
If your mysql_upgrade command reports an error in this step, it means If there is a problem with the previous step, you can execute the command in step 6 again.
service mysqld start mysql_upgrade -u root -p
