I've installed mysql(The version is:mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar) in Linux redhat, while after the installation, I can't start mysqld.service successfully.The Terminal indicates that:
[jsadmin#ahq-vsvr10-0120 new]$ sudo systemctl start mysqld.service
Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.
The result for "journalctl -xe" is:

Galera mysql node joined the cluster unsuccessfully after being abnormally stopped
We have three nodes in Galera cluster with IPs 172.21.100.23, 172.21.100.24 and 172.21.100.25. The cluster had run successfully for a year.
Recently I changed my.cnf on 23 to add some bin log configurations. After that, I restarted mysql on 23,the start command 'systemctl start mysqld' suspended, and it can not be stopped using 'systemctl stop mysqld'. So I found out mysql process id and killed it.
After that I removed the added configurations in my.cnf on 23, restoring it to the state before, but I still can not start mysql successfully.
I had looked into grastate.dat in datadir, it has following content:
version 2.1
UUID: 00000000-0000-0000-0000-000000000000
seqno:-1
safe_to_bootstrap:0
I had run 'mysqld --wsrep-recover' on 23, it executed successfully, but it had no effect.
In mysqld.log, there are some lines generated after executing 'mysqld --wsrep-recover',
Found saved state:00000000-0000-0000-0000-000000000000:-1, safe_to_bootstrap:0
it is the same as in grastate.dat.
Following is the my.cnf on 23:

Intel Turbo boost for KVM Guest
Please excuse me if this is a stupid question, however, I'm curious why I'm not seeing any clock speed differences when using fedora as a guest VM via KVM/QEMU. Perhaps this is a rather dumb way of concluding such things, but when I do cat /proc/cpuinfo | grep MHz it's always the same and it's the base clock speed advertised by my xeons. Is there some option I have to pass virsh to enable turbo boost?

The speed shown in /proc/cpuinfo inside a guest is meaningless/irrelevant. Regardless of what it says there, the CPUs will run at whatever speed the host CPUs support. IOW, if your guest is doing something CPU intensive, you can rest assured it'll max out the host CPU causing the host kernel to ramp up host CPU speed to maximum possible when needed.
