There was an error when attempting to rsync a synced folder. Please inspect the error message below for more info.

solution

apt search is the front-end of apt-cache search, it support regex by default, to search from only names of the package, pass the option --names-only

- name: create user's directorys file: path: "{{ item.path }}" state: directory mode: "{{ item.mode | default(omit) }}" loop: - { path: "{{ ansible_env.HOME }}/.ssh", mode: 0700 }

ansible complained

"bad symbolic permission for mode: 448"

the reason is that pyyaml convert octal value 0700 to int 448, and then I put the mode's value in double quote, which make 448 be treat as a string, but the module assumes that string values are octals, which cause problems. So whenever you set value for unix permission mode, always quote it as a string

如下 ansible 配置

tasks: - include_tasks: tasks/install_pkgs.yml - include_tasks: tasks/config.yml tags: config

我想只运行 tasks/config.yml 中的 tasks

ansible-playbook -i hosts local.yml --tags config

结果console输出中显示只是执行了 include_tasks: tasks/config.yml, 但是 tasks/config.yml 中的task并没有执行， config 这个 tag 只是 apply to include_tasks: tasks/config.yml, 并没有 apply to tasks/config.yml 中包含的 tasks

jenkins 执行 build 时，总是报错找不到 mvn 命令，原来是因为 The execute shell does not know about the Maven settings; only the maven job type or step does. 可以设置

export MAVEN_HOME=/opt/maven export PATH=$PATH:$MAVEN_HOME/bin

I suddenly cannot see what I am typing on terminal, but it seems I can still run command on it, after some research on the internet, I tried reset, and this fix it

as someone in stackoverflow said

edit /var/lib/jenkins/config.xml and change the following line to:

ssh server 是 centos 7 Resolution

Confirm xorg-x11-xauth package is installed.

Modify /etc/ssh/sshd_config and set AddressFamily inet and restart sshd.

If SSH client is authenticating with the public key and if there is parameter like no-agent-forwarding, no-port-forwarding, no-X11-forwarding before public key specified in ~/.ssh/authorized_keys of user's home directory on SSH server, these options need to be removed from the file.
