为什么 yum list 输出中的某些软件包的第三列在 RHEL 6/7 下“已安装”

  • 772

其实，上述问题标题中可能包含以下两个子问题：
1) rpm 包结构的开发设计如何，是否会导致 repoquery -i 输出为空？
2) 如果 rpm 包结构中没有“from_repo”属性，是否会导致通过 yum list 得到“installed”？

  1. 标记installed表示未使用 安装的软件包yum。例如，如果我这样做：

    # yumdownloader words
# rpm -ivh words-3.0-22.el7.noarch.rpm

    然后我将看到：

    # yum list installed |grep words
words.noarch                              3.0-22.el7                   installed

    一些 yum 子命令仅仅使用 rpmdb 来查询...，尤其是已安装列表和信息。

    #  
# grep -Ei "/var/lib/" /tmp/yi_strace_1.out|grep rpm|wc -l

#  
#  
# grep -Ei "/var/lib/" /tmp/yi_strace_1.out|grep rpm|tail
open("/var/lib/rpm/pubkeys", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
access("/var/lib/rpm", W_OK)            = 0
access("/var/lib/rpm/__db.001", F_OK)   = 0
access("/var/lib/rpm/Name", F_OK)       = 0
stat("/var/lib/rpm/Name", {st_mode=S_IFREG|0644, st_size=40960, ...}) = 0
stat("/var/lib/rpm/Name", {st_mode=S_IFREG|0644, st_size=40960, ...}) = 0
