      • 3、重启mysqld服务
      • 4、再次查看SSL，have_ssl的值为DISABLED，即为关闭状态

系统环境：

[dalaochao@xxzx-dalaochao-19 ~]$ cat /etc/os-release
NAME="Kylin Linux Advanced Server"
VERSION="V10 (Tercel)"
ID="kylin"
VERSION_ID="V10"
PRETTY_NAME="Kylin Linux Advanced Server V10 (Tercel)"
ANSI_COLOR="0;31"

MySQL版本：5.7.44

1、查看SSL的开启状态

SHOW VARIABLES LIKE '%ssl%';

have_openssl表示是否支持SSL。have_ssl的值为YES，表示已开启SSL。

2、修改配置文件/etc/my.cnf，添加 skip_ssl

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
port=8888

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
skip_ssl

3、重启mysqld服务

systemctl mysqld restart

4、再次查看SSL，have_ssl的值为DISABLED，即为关闭状态
