mysql：無法啟動mysqld“mysqld.service：控制進程退出，code=exited status=1”

Question

我已經安裝了第三方框架fate ，並且mysql已經安裝在這個框架內，路徑如下： /data/projects/fate/common/mysql/mysql-8.0.28 。

我已將/data/projects/fate/common/mysql/mysql-8.0.28/conf/my.conf復制到/etc/my.cnf ，內容為：

[mysqld]
port=3306
basedir=/data/projects/fate/common/mysql/mysql-8.0.28
datadir=/data/projects/fate/data/mysql
socket=/data/projects/fate/common/mysql/mysql-8.0.28/run/mysql.sock
max_connections=10000
max_connect_errors=10
character-set-server=utf8
default-storage-engine=INNODB
default_authentication_plugin=mysql_native_password
mysqlx=0
[mysql]
default-character-set=utf8
[client]
port=3306
default-character-set=utf8
socket=/data/projects/fate/common/mysql/mysql-8.0.28/run/mysql.sock
[mysqld_safe]
log-error=/data/projects/fate/common/mysql/mysql-8.0.28/logs/mysqld.log
pid-file=/data/projects/fate/common/mysql/mysql-8.0.28/run/mysqld.pid

但是當我嘗試使用systemctl start mysqld時，我得到：

Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

在systemctl status mysqld.service之后

● mysqld.service - LSB: start and stop MySQL
   Loaded: loaded (/etc/rc.d/init.d/mysqld; bad; vendor preset: disabled)
   Active: failed (Result: exit-code) since Sat 2022-05-14 16:27:43 CST; 13s ago

May 14 16:27:43 vm-0-1-centos systemd[1]: mysqld.service failed.

或者使用service mysqld start ，問題是

Starting MySQL.The server quit without updating PID file (/data/projects/fate/data/mysql/vm-0-1-centos.pid).[FAILED]

我已經嘗試了很多其他問題的解決方案，現在我被困住了，心煩意亂。 我不想重新安裝mysql，因為我擔心另一個mysql可能會影響第三方框架的fate工作。
