安装Mysql 5.6后，服务器无法启动

mysql服务器安装在一个干净的Debian 7上

已经尝试了这个次数的每一次在一个干净的Debian安装

安装

# apt-get update && apt-get upgrade # groupadd mysql # useradd -r -g mysql mysql # apt-get install libaio1 # wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.12-debian6.0-x86_64.deb # dpkg -i mysql-5.6.12-debian6.0-x86_64.deb # cd /usr/local # ln -s /opt/mysql/server-5.6 mysql # cd mysql # scripts/mysql_install_db --user=mysql --datadir=/var/lib/mysql # rm /opt/mysql/server-5.6/my.cnf # ln -s /var/ini/my.cnf /opt/mysql/server-5.6/my.cnf # cp support-files/mysql.server /etc/init.d/mysql # service mysql start

更新

现在服务器正在启动，但无法连接到MySQL

 root@Debian-70-wheezy-64-minimal ~ # mysql -u root ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

他们可能已经移动了一些东西…尝试运行mkdir /etc/mysql/conf.d/并再次启动mysql。

您的configuration包括该目录，但是它不会出现在您的服务器上，如错误消息所述。

如果这是第一次安装dbs

 mysql_install_db

在Ubuntu Precise上安装Percona 5.6时出现同样的错误。

在/ etc / mysql（/etc/mysql/conf.d/）中创build一个conf.d目录，并在apt-get清除和自动清理之后重新安装解决了问题。

你的MySQL安装有MYI和MYD文件吗？如果你这样做，你应该擦除它们，并重新启动mysql_install_db并仔细检查文件是否正常。你也应该检查你的linux权限。

错误消息告诉你到底发生了什么错误：它期望在/etc/mysql/conf.d中find一些默认的configuration信息：

 /opt/mysql/server-5.6/bin/my_print_defaults: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)

你是否创build了该目录，并使用相应的configuration文件进行填充？

另外，这个：
