Kafka安装和启用
## 解压命令:
tar -zxvf kafka_2.12-2.1.0.tgz -C /usr/local/
## 改名命令:
mv kafka_2.12-2.1.0/ kafka_2.12
## 进入解压后的目录,修改server.properties文件:
vim /usr/local/kafka_2.12/config/server.properties
## 修改配置:
broker.id=0
port=9092
host.name=192.168.11.51
advertised.host.name=192.168.11.51
log.dirs=/usr/local/kafka_2.12/kafka-logs
num.partitions=2
zookeeper.connect=192.168.11.111:2181,192.168.11.112:2181,192.168.11.113:2181
## 建立日志文件夹:
mkdir /usr/local/kafka_2.12/kafka-logs
##启动kafka:
/usr/local/kafka_2.12/bin/kafka-server-start.sh /usr/local/kafka_2.12/config/server.properties &
## 创建topic
kafka-topics.sh --zookeeper 192.168.11.111:2181 --create --topic app-log-collector --partitions 1 --replication-factor 1
kafka-topics.sh --zookeeper 192.168.11.111:2181 --create --topic error-log-collector --partitions 1 --replication-factor 1
kafka-topics.sh --zookeeper 192.168.11.111:2181 --topic app-log-test --describe
filebeat安装和启用:
cd /usr/local/software
tar -zxvf filebeat-6.6.0-linux-x86_64.tar.gz -C /usr/local/
cd /usr/local
mv filebeat-6.6.0-linux-x86_64/ filebeat-6.6.0
vim /usr/local/filebeat-5.6.2/filebeat.yml

logstash安装
mkdir scrpit
cd scrpit
vim logstash-script.conf
## multiline 插件也可以用于其他类似的堆栈式信息,比如 linux 的内核日志。
