1、收集Nginx的json格式日志
1.1、Nginx安装
[root@linux-node1 ~]# yum install nginx -y [root@linux-node1 ~]# vim /etc/nginx/nginx.conf #修改日志格式为json格式，并创建一个nginxweb的网站目录 log_format access_json '{"@timestamp":"$time_iso8601",' '"host":"$server_addr",' '"clientip":"$remote_addr",' '"size":$body_bytes_sent,' '"responsetime":$request_time,' '"upstreamtime":"$upstream_response_time",' '"upstreamhost":"$upstream_addr",' '"http_host":"$host",' '"url":"$uri",' '"domain":"$host",' '"xff":"$http_x_forwarded_for",' '"referer":"$http_referer",' '"status":"$status"}'; access_log /var/log/nginx/access.log access_json; location /nginxweb { root html; index index.html index.htm; } [root@linux-node1 ~]# mkdir /usr/share/nginx/html/nginxweb [root@linux-node1 ~]# echo "<h1> welcome to use Nginx" > /usr/share/nginx/html/nginxweb/index.html [root@linux-node1 ~]# nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [root@linux-node1 ~]# systemctl start nginx
1.2、配置logstash
[root@linux-node1 ~]# vim /etc/logstash/conf.d/nginx-accesslog.conf input{ file { path => "/var/log/nginx/access.log" type => "nginx-access-log" start_position => "beginning" stat_interval => "2" } } output{ elasticsearch { hosts => ["192.168.56.11:9200"] index => "logstash-nginx-access-log-%{+YYYY.MM.dd}" } file { path => "/tmp/logstash-nginx-access-log-%{+YYYY.MM.dd}" } } [root@linux-node1 ~]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/nginx_access.conf -t [root@linux-node1 ~]# systemctl restart logstash
1.3、配置Kibana展示
[root@linux-node1 ~]# ab -n1000 -c 100 http://192.168.56.11/nginxweb/index.html #对页面压测 [root@linux-node1 ~]# tailf /var/log/nginx/access.log #nginx的访问日志变成了json格式 {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"} {"@timestamp":"2017-12-27T16:38:17+08:00","host":"192.168.56.11","clientip":"192.168.56.11","size":26,"responsetime":0.000,"upstreamtime":"-","upstreamhost":"-","http_host":"192.168.56.11","url":"/nginxweb/index.html","domain":"192.168.56.11","xff":"-","referer":"-","status":"200"}

2、Tomcat的json日志收集
2.1、下载tomcat
[root@linux-node2 ~]# wget http://apache.fayea.com/tomcat/tomcat-8/v8.5.20/bin/apache-tomcat-8.5.20.tar.gz [root@linux-node2 ~]# tar -zxf apache-tomcat-8.5.24.tar.gz [root@linux-node2 ~]# mv apache-tomcat-8.5.24 /usr/local/tomcat
2.2、修改tomcat日志格式
[root@linux-node2 ~]# cd /usr/local/tomcat/conf [root@linux-node2 conf ]# cp server.xml{,.bak} [root@linux-node2 conf ]# vim server.xml <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="tomcat_access_log" suffix=".log" pattern="{"clientip":"%h","ClientUser":"%l","authenticated":"%u","AccessTime":"%t","method":"%r","status":"%s","SendBytes":"%b","Query?string":"%q","partner":"%{Referer}i","AgentVersion":"%{User-Agent}i"}"/>
2.3、增加tomcat网页
[root@linux-node2 conf ]# cd ../webapps/ [root@linux-node2 webapps ]# mkdir webdir && cd webdir [root@linux-node2 webdir ]# echo "<h1>welcome to use tomcat</h1>" > index.html [root@linux-node2 conf ]# ../bin/catalina.sh start [root@linux-node2 conf ]# netstat -tulnp |grep 8080 tcp6 0 0 :::8080 :::* LISTEN 2362/java
2.4、压测页面，生成tomcat的访问日志
[root@linux-node2 conf ]# ab -n1000 -c100 http://192.168.56.12:8080/webdir/index.html [root@linux-node2 ~]# tailf /usr/local/tomcat/logs/tomcat_access_log.2017-12-28.log {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:56 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"} {"clientip":"192.168.56.12","ClientUser":"-","authenticated":"-","AccessTime":"[28/Dec/2017:09:52:57 +0800]","method":"GET /webdir2/index.html HTTP/1.0","status":"200","SendBytes":"32","Query?string":"","partner":"-","AgentVersion":"ApacheBench/2.3"}
2.5、配置logstash
[root@linux-node2 ~]# vim /etc/logstash/conf.d/tomcat_accesslog.conf input { file { path => "/usr/local/tomcat/logs/tomcat_access_log.*.log" type => "tomcat-accesslog" start_position => "beginning" stat_interval => "2" } } output { elasticsearch { hosts => ["192.168.56.11:9200"] index => "logstash-tomcat5612-accesslog-%{+YYYY.MM.dd}" } file { path => "/tmp/logstash-tomcat5612-accesslog-%{+YYYY.MM.dd}" } }
2.6、检查logstash的配置语法并重启logstash
[root@linux-node2 tomcat]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/tomcat_accesslog.conf -t OpenJDK 64-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 tomcat]# systemctl restart logstash [root@linux-node2 tomcat]# ps -ef |grep logstash logstash 2527 1 98 09:33 ? 00:00:28 /bin/java -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC -Djava.awt.headless=true -Dfile.encoding=UTF-8 -XX:+HeapDumpOnOutOfMemoryError -Xmx1g -Xms256m -Xss2048k -Djffi.boot.library.path=/usr/share/logstash/vendor/jruby/lib/jni -Xbootclasspath/a:/usr/share/logstash/vendor/jruby/lib/jruby.jar -classpath : -Djruby.home=/usr/share/logstash/vendor/jruby -Djruby.lib=/usr/share/logstash/vendor/jruby/lib -Djruby.script=jruby -Djruby.shell=/bin/sh org.jruby.Main /usr/share/logstash/lib/bootstrap/environment.rb logstash/runner.rb --path.settings /etc/logstash root 2572 15939 0 09:34 pts/3 00:00:00 grep --color=auto logstash
2.7、elasticsearch的head插件查看
数据浏览：
注：此处如果无法出现tomcat的数据索引，查看一下是否有权限访问日志。
[root@linux-node2 logs]# ll /usr/local/tomcat/logs/ -d drwxr-x--- 2 root root 4096 12月 28 09:29 /usr/local/tomcat/logs/ [root@linux-node2 logs]# chmod 755 /usr/local/tomcat/logs [root@linux-node2 logs]# ll /usr/local/tomcat/logs/ 总用量 512 -rw-r----- 1 root root 7140 12月 28 09:29 catalina.2017-12-28.log -rw-r----- 1 root root 7140 12月 28 09:29 catalina.out -rw-r----- 1 root root 0 12月 28 09:29 host-manager.2017-12-28.log -rw-r----- 1 root root 284 12月 28 09:29 localhost.2017-12-28.log -rw-r----- 1 root root 0 12月 28 09:29 manager.2017-12-28.log -rw-r----- 1 root root 502039 12月 28 09:47 tomcat_access_log.2017-12-28.log [root@linux-node2 logs]# chmod 644 /usr/local/tomcat/logs/
2.8、添加到Kibana
3、Java日志收集
使用codec的multiline插件实现多行匹配，这是一个可以将多行进行合并的插件，而且可以使用what指定将匹配到的行与前面的行合并还是和后面的行合并。
https://www.elastic.co/guide/en/logstash/6.0/plugins-codecs-multiline.html
语法例子： input { stdin { codec => multiline { #使用multiline插件 pattern => "pattern, a regexp" #正则匹配 negate => "true" or "false" #匹配是否成功 what => "previous" or "next" #和上面的还是和下面的内容合并 } } } 命令行测试输入输出 [root@linux-node1 ~]# /usr/share/logstash/bin/logstash -e 'input { stdin {codec => multiline { pattern => "^[" negate => "true" what => "previous"} }} output { stdout {codec => rubydebug}}' OpenJDK 64-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.

（3）elasticsearch的head插件查看
数据浏览：
（4）添加到Kibana
可以看到以“[”开头的信息都合并了，如图：
4、TCP收集日志使用场景
tcp模块的使用场景如下： 有一台服务器A只需要收集一个日志，那么我们就可以不需要在这服务器上安装logstash，我们通过在其他logstash上启用tcp模块，监听某个端口，然后我们在这个服务器A把日志通过nc发送到logstash上即可。
4.1、标准输出测试TCP模块
[root@linux-node2 ~]# cat /etc/logstash/conf.d/tcp.conf input { tcp{ port => "5600" #监听5600端口 mode => "server" #模式为server type => "tcplog" #类型为tcplog } } output { stdout { codec => rubydebug } } #检测配置文件语法： [root@linux-node2 conf.d]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/tcp.conf -t OpenJDK 64-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.
