    Filebeat(多台)


    架构存在的问题
    1. Logstash性能不足的时候
    2. 扩容Logstash，Filebeat的配置可能会不一致

    架构优化
    Filebeat(多台) Logstash
    Filebeat(多台) -> Redis、Kafka -> Logstash(正则) -> Elasticsearch(入库) -> Kibana展现

    部署服务介绍
    3. 192.168.10.11 Kibana ES
    4. 192.168.10.12 Logstash Filebeat Redis

    Redis服务器搭建
    yum install -y wget net-tools gcc gcc-c++ make tar openssl openssl-devel cmake
    cd /usr/local/src
    wget http://download.redis.io/releases/redis-4.0.9.tar.gz
    tar xvf redis-4.0.9.tar.gz
    cd redis-4.0.9
    make
    mkdir -pv /usr/local/redis/conf /usr/local/redis/bin
    cp src/redis* /usr/local/redis/bin/
    cat redis.conf | grep -v “#” | grep -v “^$” > /usr/local/redis/conf/redis.conf

    验证Redis服务器
    5. 更改Redis配置（daemon、dir、requirepass）
    6. 密码设置为jaking
    7. 验证set、get操作
