对于日志传输，rsyslog或者logstash也就够用了，一般的redis，kafka，主要是作为缓冲或序列防止logstash挂掉后，日志中断，下面写kafka的使用。
在用kafka之前，需要rsyslog模块支持，所以需要对rsyslog升级，并且启用omkafka，下面对rsyslog升级同时加入omhiredis：
下载https://github.com/rsyslog/rsyslog/archive/master.zip
rsyslog编译安装过程中会遇到种种问题，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 installed software in a non-standard prefix. Alternatively, you may set the environment variables HIREDIS_CFLAGS and HIREDIS_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
下面为rsyslog安装升级步骤：
# yum install autoconf liblogging-devel
# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# yum -y install hiredis hiredis-devel libgt-devel libksi-devel librelp-devel liblognorm1-devel liblognorm1-devel liblognorm1-devel libmongo-client-devel adiscon-librdkafka-devel libnet-devel
# yum -y install pkgconfig libuuid* libgcrypt-devel zlib-devel byacc mysql-devel
# wget http://libestr.adiscon.com/files/download/libestr-0.1.9.tar.gz
# tar xvf libestr-0.1.9.tar.gz
# cd libestr
# ./configure && make && make install
# wget https://github.com/downloads/json-c/json-c/json-c-0.10.tar.gz
# tar xvf json-c-0.10.tar.gz
# cd json-c
# ./configure && make && make install
# cp ../json-c-0.10/json_object_iterator.h /usr/local/include/json/
# wget https://pypi.python.org/packages/source/d/docutils/docutils-0.11.tar.gz --no-check-certificate
# python setup.py install
# ln -s /usr/bin/rst2man.py /usr/bin/rst2man
wget https://github.com/redis/hiredis/archive/master.zip
cd ../hiredis-master
make
Generating hiredis.pc for pkgconfig... 生成了hiredis.pc文件
# cat /usr/lib64/pkgconfig/hiredis.pc
prefix=/usr/local
exec_prefix=${prefix}
libdir=/usr/local/lib
includedir=/usr/local/include/hiredis
Name: hiredis
Description: Minimalistic C client library for Redis.
Version: 0.13.3
Libs: -L${libdir} -lhiredis
Cflags: -I${includedir} -D_FILE_OFFSET_BITS=64
cp hiredis.pc /usr/lib64/pkgconfig/
./configure --enable-omkafka --enable-omhiredis PKG_CONFIG_PATH=/usr/lib64/pkgconfig --libdir=/usr/lib64
或者更详细的编译操作
