我在mariaDB上有几个复制设置(最新版本:10.1.8).请确保我使用的Multiple replication不是遗产Single replication.
我已经用CHANGE MASTER "blah" TO命令添加了一些设置.现在我想从中删除其中一个show all slaves status.
mysql -e "show all slaves status\G;" | grep "Connection_name\|Running"
Connection_name:
Slave_IO_Running: No
Slave_SQL_Running: Yes
Connection_name: asi.exapmle.com
Slave_IO_Running: Connecting
Slave_SQL_Running: Yes
Connection_name: bee.exapmle.com
Slave_IO_Running: Connecting
Slave_SQL_Running: Yes
Connection_name: dild.exapmle.com
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
Connection_name: datr.exapmle.com
Slave_IO_Running: Connecting
Slave_SQL_Running: Yes
Connection_name: db.exapmle.com
Slave_IO_Running: Connecting
Slave_SQL_Running: Yes
Connection_name: nop.exapmle.com
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
如何db.exapmle.com在不影响其他复制的情况下仅从此复制列表中删除？
Google Kubernetes Engine 的这个教程似乎不起作用。
https://cloud.google.com/kubernetes-engine/docs/tutorials/hello-app
$ gcloud beta container clusters create hello-cluster --num-nodes=3
WARNING: You invoked `gcloud beta`, but with current configuration Kubernetes Engine v1 API will be used instead of v1beta1 API.
`gcloud beta` will switch to use Kubernetes Engine v1beta1 API by default by the end of March 2018.
If you want to keep using `gcloud beta` to talk to v1 API temporarily, please set `container/use_v1_api` property to true.
But we will drop the support for this property …这有效：
ansible host -a "echo hello" # hello
但这返回了一个奇怪的答案
ansible host -a "echo hello && echo world" # hello && echo world
ansible 是否会逃脱&&and ;with ansible -a？
我怎样才能执行它？
我正在创建网站的搜索功能。我需要将用户输入的句子类型提取到列表中，但要求引号中的单词应成为列表的一项。
在我的期望中，请专注于杰夫·沃森和纽约一词。
期望：
str = 'Hello, I am "Jeff Watson" from a part of "New York".'
result = ["Hello", "I", "am", "Jeff Watson", "from", "a", "part", "of", "New York"]
如果您的答案也使用单引号，那是最好的。
