After all these tasks are completed, you can establish user equivalence. You are not prompted to enter a password when you establish a user equivalence.

Dynamic agents are widely used, spring,struts and other frameworks are implemented through dynamic proxies or further encapsulation. The common dynamic proxy pattern implementation has the dynamic proxy provided by the Java API and the third party open source class library Cglib dynamic agent. The dynamic proxies provided by the Java API are implemented based on class reflection, and the classes used are: Java.lang.reflect.InvocationHandler; Java.lang
Set the global proxy as follows:Modify the/etc/profile file to add the following:Http_proxy=http://username:[email protected]:8080/Ftp_proxy=http://username:[email protected]:8080/Export Http_proxyExport Ftp_proxyIf there is no password limit, the above content can be modified to the following:http_proxy=http://yourproxy:8080/ftp_proxy=http://yourproxy:8080/Export Http_proxyExport Ftp_proxyIf only for a user, then modify the ~/.bash_profile file, add the same content;After the modification is co

Authentication Method for SSh service logon:
Password-based security verification
1. When the client initiates an ssh request, the server will send its own public key
localhost
The result is as follows:
The problem is analyzed as follows: openssh-server is not installed in Ubuntu by default. We can use a command to check that openssh-server is not installed if only the agent is installed. The command is as follows:
Ps-e | grep ssh
The effect is as follows:
Now that the problem is found, run the following command to install openssh-server:
Sudo apt-get install openssh-

SSH to the 192.168.88.61 machine requires a password, which is inconvenient for some scripts because of the need for a password, which requires manual intervention.

SSH to the 163 host requires a password, which is inconvenient for some scripts because the password is required, that is, manual intervention is required. The method used previously was to copy the authorized_keys file (I can't remember it, I used it before). Recently, I found a command ssh-copy-ID is very convenient. I tried it and it really worked well. It was recorded below:

It is mainly because the fedora core2 encoding is UTF-8, so it cannot be correctly displayed.
1. temporary solution:
Run the following command every time you log on via SSH:
Chinese: Export lang = zh_cn.gb2312
English: Export lang = "en_us"
Export lc_all = "en_us"
For example, [root @ localhost ~] # Export lang = zh_cn.gb2312
2. (FIND) a stable solution:The
When using Taskctl to dispatch a service, if you need cross-user or cross-server scheduling can be implemented by installing TASKCTL agent, but sometimes there are only a few scripts on the server that needs to execute the job, then deploying the agent at this time is a bit of a loss. We know that Taskctl supports any type of job extension, so we can consider using SSH
