max connection 是mysql的global 变量, 可以查看变量
SHOW WARNINGS;
show variables like "max_connections";
如果要设置max connections, 修改 mysqld.cnf
sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf
Add
max_connections=1000
max connection变量受到系统的open_files_limit 限制,因为是service,可以修改sysctl 变量来increase open files。如果
sudo vi /etc/sysctl.conf
Add
fs.file-max=34166
