#### SRS

###srs rpm upgrade
rpm -Uvh srs.rpm

###srs rpm downgrade
rpm -Uvh --oldpackage srs.rpm

###srs 強制安裝新版
rpm -ivh --force srs.rpm


不論升或降板 srs.conf都不會被砍掉 所以如果有版本差異要注意conf有沒有不支援的部分

升降板之後都要restart後才會生效


###卸載
yum remove srs

srs.conf會被砍掉

#### SRS Log

建立規則
## srslog ##

touch /etc/logrotate.d/srslog

vi /etc/logrotate.d/srslog

/usr/local/srs/objs/srs.log {
    daily
    rotate 7
    compress
    delaycompress
    copytruncate
    missingok
    dateext
    dateformat .%Y%m%d
    sharedscripts
}

加入排程
logrotate -f /etc/logrotate.d/srslog



## srs gateway log ## (flv edge)

touch /etc/logrotate.d/srsgwlog

vi /etc/logrotate.d/srsgwlog

/usr/local/srs-http-stream-gateway/logs/srs-http-stream-gateway.log {

    compress
    delaycompress
    copytruncate
    missingok
