搭建该日志查询系统的目的就是为了运维、研发很方便的进行日志的查询。Kibana 一个免费的 web 壳;Logstash 集成各种收集日志插件,还是一个比较优秀的正则切割日志工具;Elasticsearch 一个开源的搜索引擎框架(支持群集架构方式)。

3 相关配置及启动
首先需要提前启动消息队列(redis),Elasticsearch 服务,假如不提前启动,而去启动 logstash 会有报错,原因 logstash 不能连接对应的服务。
3.1 Redis 配置及启动
3.1.1 配置文件
vim /data/redis/etc/redis.conf
#—————————————————-
#this is the config file for redis
pidfile /var/run/redis.pid
port 6379
timeout 0
loglevel verbose
logfile /data/redis/log/redis.log
databases 16
save 900 1
save 300 10
save 60 10000
rdbcompression yes
dbfilename dump.rdb
dir /data/redis/db/
slave-serve-stale-data yes
appendonly no
appendfsync everysec
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb

zset-max-ziplist-entries 128
zset-max-ziplist-value 64
activerehashing yes
3.1.2 Redis 启动(192.168.50.98)
[logstash@Logstash_2 redis]# redis-server /data/redis/etc/redis.conf &
3.2 Elasticsearch 配置及启动(192.168.50.98)
3.2.1 Elasticsearch 启动
[logstash@Logstash_2 redis]# /data/elasticsearch/elasticsearch-0.18.7/bin/elasticsearch –p ../esearch.pid &
3.3 Logstash 配置及启动
3.3.1 Logstash 配置文件(agent 收集日志角色)
配置文件
input {
file{
type => “linux-syslog”
path => [“/var/log/*.log”, “/var/log/messages”, “/var/log/syslog”]
}
file {
type => “nginx-access”
path => “/usr/local/nginx/logs/access.log”
}
file {
type => “nginx-error”
path => “/usr/local/nginx/logs/error.log”
}
}
output {
redis {
host => “192.168.50.98”
data_type =>”list”
key => “logstash:redis”
}
}
Agent 启动方法
java -jar logstash-1.1.0-monolithic.jar agent -f shipper.conf &
3.3.2 Logstash 启动为 Index(从 redis 读取日志,负责日志的切割,存储至 Elasticsearch)
input {
redis {
host => “192.168.50.98”
data_type =>”list”
key => “logstash:redis”
type => “redis-input”
}
}
filter {
grok {
type => “linux-syslog”
pattern => “%{SYSLOGLINE}”
}
grok {
type => “nginx-access”
pattern => “%{NGINXACCESSLOG}”
}
}
output {
elasticsearch {
host =>”192.168.50.62″
}
}
启动方法
java -jar logstash.jar agent -f my.conf &
3.3.4 kibana 配置
首先在 nginx 添加站点配置
server {
listen 80;
server_name logstash.test.com;
index index.php;
root /usr/local/nginx/html;
#charset koi8-r;
#access_log logs/host.access.log main;
location ~ .*\.(php|php5)$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
4 性能调优
4.1 Elasticsearch 调优
4.1.1 JVM 调优
编辑 Elasticsearch.in.sh 文件
ES_CLASSPATH=$ES_CLASSPATH:$ES_HOME/lib/*:$ES_HOME/lib/sigar/*
if [“x$ES_MIN_MEM” = “x”]; then
ES_MIN_MEM=4g
fi
if [“x$ES_MAX_MEM” = “x”]; then
ES_MAX_MEM=4g
fi
4.1.2 Elasticsearch 索引压缩
vim index_elastic.sh
#!/bin/bash
#comperssion the data for elasticsearch now
date=` date +%Y.%m.%d `
# compression the new index;
/usr/bin/curl -XPUT http://localhost:9200/logstash-$date/nginx-access/_mapping -d ‘{“nginx-access” : {“_source” : { “compress” : true}}}’
echo “”
/usr/bin/curl -XPUT http://localhost:9200/logstash-$date/nginx-error/_mapping -d ‘{“nginx-error” : {“_source” : { “compress” : true}}}’
echo “”
/usr/bin/curl -XPUT http://localhost:9200/logstash-$date/linux-syslog/_mapping -d ‘{“linux-syslog” : {“_source” : { “compress” : true}}}’
echo “”
保存该脚本并执行
sh index_elastic.sh
