Linux下重启mysql:
systemctl restart mysqld
出现以下错误:
Error getting authority: Error initializing authority: Could not connect: Resource temporarily unavailable (g-io-error-quark, 27)
wget https://copr.fedorainfracloud.org/coprs/jsynacek/systemd-backports-for-centos-7/repo/epel-7/jsynacek-systemd-backports-for-centos-7-epel-7.repo -O /etc/yum.repos.d/jsynacek-systemd-centos-7.repo
yum update systemd
希望对各位有所帮助。
