1、部署Redis
1.1、下载redis
[root@linux-node2 ~]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz
[root@linux-node2 ~]# tar -zxvf redis-4.0..tar.gz
[root@linux-node2 ~]# mv redis-4.0. /usr/loca/src
[root@linux-node2 ~]# cd /usr/local/src/redis-4.0.
[root@linux-node2 redis-4.0.]# make
[root@linux-node2 redis-4.0.]# ln -sv /usr/local/src/redis-4.0. /usr/local/redis
[root@linux-node2 redis-4.0.]# cd /usr/local/redis
1.2、配置redis
[root@linux-node2 redis]# vim redis.conf
bind 192.168.56.12
daemonize yes
save ""
requirepass #开启认证
[root@linux-node2 redis]# cp /usr/local/src/redis-4.0./src/redis-server /usr/bin/
[root@linux-node2 redis]# cp /usr/local/src/redis-4.0./src/redis-cli /usr/bin/
[root@linux-node2 redis]# redis-server /usr/local/redis/redis.conf
:C Jan ::26.801 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
:C Jan ::26.801 # Redis version=4.0., bits=, commit=, modified=
:C Jan ::26.801 # Configuration loaded
1.3、测试redis
[root@linux-node2 ~]# netstat -tulnp |grep
tcp 192.168.56.12: 0.0.0.0:* LISTEN /redis-server
[root@linux-node2 redis]# redis-cli -h 192.168.56.12
192.168.56.12:> KEYS *
(error) NOAUTH Authentication required.
192.168.56.12:> auth
OK
192.168.56.12:> KEYS *
(empty list or set)
192.168.56.12:> quit
2、配置logstash将日志写入redis
2.1、配置logstash的system.conf
[root@linux-node1 conf.d]# vim system.conf
input {
file {
path => "/var/log/messages"
type => "systemlog"
start_position => "beginning"
stat_interval => ""
}
}output {
if [type] == "systemlog" {
redis {
data_type => "list"
host => "192.168.56.12"
db => ""
port => ""
password => ""
key => "systemlog"
}
}}
2.2、检测配置语法
[root@linux-node1 conf.d]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/sy
OpenJDK -Bit Server VM warning: If the number of processors is expected to increase CThreads=N
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or
Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properti
Configuration OK
[root@linux-node1 conf.d]# systemctl restart logstash
2.3、写入messages日志测试
[root@linux-node1 conf.d]# cat /etc/hosts >> /var/log/messages
[root@linux-node1 conf.d]# echo "helloword" >> /var/log/messages
2.4、登陆redis中查看
[root@linux-node2 ~]# redis-cli -h 192.168.56.12
192.168.56.12:> KEYS *
(error) NOAUTH Authentication required.
192.168.56.12:> AUTH
OK
192.168.56.12:>
192.168.56.12:> select
OK
192.168.56.12:[]> KEYS *
) "systemlog"
192.168.56.12:[]> LLEN systemlog #查看key的长度
(integer)
192.168.56.12:[]> LLEN systemlog
(integer)
192.168.56.12:[]> LPOP systemlog #展示一条记录会减少一条
"{\"@version\":\"1\",\"host\":\"linux-node1\",\"path\":\"/var/log/messages\",\"@timestamp\":\"2018-01-02T03:04:40.424Z\",\"type\":\"systemlog\",\"tags\":[\"_geoip_lookup_failure\"]}"
192.168.56.12:[]> LLEN systemlog
(integer)
3、配置logstash从reids中取出数据到elasticsearch
3.1、使用linux-node2上的logstash从redis取数据
[root@linux-node2 conf.d]# vim redis-es.conf
input {
redis {
data_type => "list"
host => "192.168.56.12"
db => ""
port => ""
key => "systemlog"
password => ""
}
}output {
elasticsearch {
hosts => ["192.168.56.11:9200"]
index => "redis-systemlog-%{+YYYY.MM.dd}"
}
}
[root@linux-node2 conf.d]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/redis-es.conf -t
OpenJDK -Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console
Configuration OK
[root@linux-node2 conf.d]# systemctl restart logstash
3.2、从linux-node1上写入数据查看
[root@linux-node1 conf.d]# cat /etc/passwd >> /var/log/messages
[root@linux-node2 ~]# redis-cli -h 192.168.56.12
192.168.56.12:> KEYS *
(error) NOAUTH Authentication required.
192.168.56.12:> AUTH
OK
192.168.56.12:> select
OK
192.168.56.12:[]> KEYS *
) "systemlog"
192.168.56.12:[]> LLEN systemlog #查看数据长度为38
(integer)
192.168.56.12:[]> LLEN systemlog #配置成功logstash从redis中取完数据,redis长度变成0
(integer)
3.3、head插件和Kibana添加索引查看
