mysql5.7 作为openstack的数据库添加bind-address 字段之后mysql不能起来

参考   https://dba.stackexchange.com/questions/64581/mysql-bind-address-0-0-0-0-in-my-cnf-does-not-work

在my.cnf  [mysqld]中

要在bind-address之前加入此关键词方能把mysqld起来

[mysqld]
user = mysql
port=3306
socket          = /opt/lampp/var/mysql/mysql.sock
skip-external-locking
key_buffer = 16M

max_allowed_packet = 1M

table_open_cache = 64

sort_buffer_size = 512K

net_buffer_length = 8K

read_buffer_size = 256K

read_rnd_buffer_size = 512K

myisam_sort_buffer_size = 8M

plugin_dir = /opt/lampp/lib/mysql/plugin/
#skip-networking
bind-address=0.0.0.0

下面是优化的参数
