本文轉(zhuǎn)載于?http://bbotte.com/? ELK日志服務(wù)使用-kafka傳輸日志
對于日志傳輸，rsyslog或者logstash也就夠用了，一般的redis，kafka，主要是作為緩沖或序列防止logstash掛掉后，日志中斷，下面寫kafka的使用。
在用kafka之前，需要rsyslog模塊支持，所以需要對rsyslog升級，并且啟用omkafka，下面對rsyslog升級同時加入omhiredis：

rsyslog編譯安裝過程中會遇到種種問題，如下：
checking?for?LIBLOGGING_STDLOG...?no
configure:?error:?Package?requirements?(liblogging-stdlog?>=?1.0.3)?were?not?met:
No?package?'liblogging-stdlog'?found
Consider?adjusting?the?PKG_CONFIG_PATH?environment?variable?if?you
installed?software?in?a?non-standard?prefix.
Alternatively,?you?may?set?the?environment?variables?LIBLOGGING_STDLOG_CFLAGS
and?LIBLOGGING_STDLOG_LIBS?to?avoid?the?need?to?call?pkg-config
checking?for?HIREDIS...?configure:?error:?Package?requirements?(hiredis?>=?0.10.1)?were?not?met:
No?package?'hiredis'?found
Consider?adjusting?the?PKG_CONFIG_PATH?environment?variable?if?you

Alternatively,?you?may?set?the?environment?variables?HIREDIS_CFLAGS
and?HIREDIS_LIBS?to?avoid?the?need?to?call?pkg-config.
