正如标题所示，我正试图在Ansible上安装Debian上的MySQL Server 5.5。
由于这需要进行无提示安装，所以在使用debconf模块安装之前，我提供了root密码。 这是这个输出：
changed: [nqdo-net] => (item={'value': {'type': 'password', 'name': 'mysql-server/root_password', 'value': u'XXXXthisismyrandomandlongpasswordXXXX'}, 'key': 'root_password'}) changed: [nqdo-net] => (item={'value': {'type': 'password', 'name': 'mysql-server/root_password_again', 'value': u'XXXXthisismyrandomandlongpasswordXXXX'}, 'key': 'root_password_again'}) 我写了一个安装Tripwire的angular色，就像一个魅力一样。 但不幸的是，MySQL安装失败，出现以下消息：

任何想法如何解决这个问题？
提前致谢！
注意：如果你是downvoting，至less告诉我为什么！
这是你的问题：
InnoDB: mmap(137363456 bytes) failed; errno 12
那个errno意味着当MySQL试图启动时你内存不足了。 要么减lessMySQL使用的内存量，要么给机器更多的RAM。
