明明使用 公私钥 登陆,确提示密码不对。
使用 chage 来防止密码过期。
查看当前的过期时间
chage -l vagrant Last password change : never Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7
设置密码永不过期
chage -m 0 -M 99999 -I -1 -E -1 vagrant
统计集合 key 的 member 的数量
SCARD hello:step:3000:obj_type0
fork 之后做自己的功能,要与源库进行功能合并时用 MergeRequest
但是如果自己的库与源库落后太多,则可以这样
查看远程 repo
git remote -v
如果里面只能看到你自己的两个源(fetch 和 push),那就需要添加主repo的源:
git remote add upstream URL git remote -v
如果想与主repo合并:
git fetch upstream git merge upstream/master 或 git rebase upstream/master

添加配置文件
cat /etc/logrotate.d/myservice
/data/log/myservice/*.log
{
rotate 7
daily
dateext
dateformat .%Y%m%d
compress
missingok
notifempty
sharedscripts
postrotate
/usr/bin/killall -HUP rsyslogd >/dev/null 2>&1 || true
endscript
}
debug 配置文件是否正确,但不会真正动你的 log
logrotate -d /etc/logrotate.d/myservice
真实测试 logrotate 情况
logrotate -f /etc/logrotate.d/myservice
