标签: linux install rsyslog

我有一个安装后脚本:

unset DEBIAN_HAS_FRONTEND DEBIAN_FRONTEND DEBCONF_REDIR DEBCONF_OLD_FD_BASE
export DEBIAN_FRONTEND=noninteractive
aptitude -y install rsyslog-pgsql > /var/tmp/log 2>&1

安装时(ps ax):

17587 tty1     S+     0:00 /bin/sh /var/lib/dpkg/info/rsyslog-pgsql.postinst configure
17828 tty1     S+     0:00 whiptail --backtitle Package configuration --title Configuring rsyslog-pgsql --output-fd 11 --nocancel --msgbox An error occurred while installing the database:  Password: su: System error  If at this point you choose "retry", you will be prompted with all the  configuration questions once more and another attempt will be made at  performing the operation. "retry (skip questions)" will immediately  attempt the operation again, skipping all questions.  If you choose  "abort", the operation will fail and you will need to downgrade,  reinstall, reconfigure this package, or otherwise manually intervene to  continue using it.  If you choose "ignore", the operation will continue, ignoring further errors from dbconfig-common. 18 77

  1. 安装包

    $ sudo apt -q -y install pkg
    
  2. 安装debconf utils

    # if you don't know the question
    $ sudo apt install debconf-utils
    
  3. 找到问题('什么是矩阵?')

    # find the question you need answered (use less instead)
    $ sudo debconf-get-selections | grep pkg
    
  4. 卸载包(清除)

    $ sudo apt-get purge pkg
    
  5. 设置您需要回答的选择

    echo 'pkg       thequestionname      type value' | sudo debconf-set-selections;
    
  6. 安装包

    sudo apt-get install pkg
    
  7. 如果您升级有新问题的软件包,您可以在vagrant上运行升级,找到在生产环境中自动升级之前预先设置的问题。

        man debconf-set-selections
