1. 部署环境
2. 架构拓扑
3. nginx安装
安装在192.168.176.128服务器上
这里安装就简单粗暴了直接yum安装nginx
[root@manager ~]# yum -y install epel-release [root@manager ~]# yum -y install nginx 检查是否安装成功(这里选择了查看版本号) [root@manager ~]# nginx -V nginx version: nginx/1.12.2 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_auth_request_module --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-google_perftools_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E'
设置日志的格式(改为json格式)并测试查看日志
[root@manager ~]# cat /etc/nginx/nginx.conf
修改成下面的部分(运维的一看就能明白是什么意思)

检查并启动 nginx 服务
[root@manager ~]# nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [root@manager ~]# systemctl start nginx [root@manager ~]# netstat -lntup | grep nginx tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1888/nginx: master tcp6 0 0 :::80 :::* LISTEN 1888/nginx: master
测试访问nginx并查看日志记录
# 测试
[root@manager ~]# curl 192.168.176.128
查看日志(这里可以看到我们自定义的日志格式输出)
[root@manager ~]# cat /var/log/nginx/access.log
{ "@timestamp": "2018-11-18T01:28:49-05:00", "remote_addr": "192.168.176.128", "remote_user": "-", "body_bytes_sent": "3700", "request_time": "0.000", "status": "200", "request_uri": "/", "request_method": "GET", "http_referrer": "-", "http_x_forwarded_for": "-", "http_user_agent": "curl/7.29.0"}
安装JDK
[root@manager ELK]# yum -y install java-1.8.0-openjdk
Nginx 就先到这里，对我们的整个环境这样就足够了
4. redis安装
安装在192.168.176.129服务器上
redis 也是直接yum简单粗暴的安装了
[root@node1 ~]# yum -y install epel-release [root@node1 ~]# yum -y install redis 检查是否安装成功(查看版本) [root@node1 ~]# redis-server -v Redis server v=3.2.12 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=7897e7d0e13773f
修改redis配置文件(监听地址和密码)
[root@node1 ~]# vim /etc/redis.conf 修改两个地方 bind 127.0.0.1 改为 bind 0.0.0.0 # requirepass foot 去掉注释 foot改为自己的密码
查看修改后的配置文件
监听地址 [root@node1 ~]# cat /etc/redis.conf | grep bind # By default, if no "bind" configuration directive is specified, Redis listens # the "bind" configuration directive, followed by one or more IP addresses. # bind 192.168.1.100 10.0.0.1 # bind 127.0.0.1 ::1 # internet, binding to all the interfaces is dangerous and will expose the # following bind directive, that will force Redis to listen only into bind 0.0.0.0 # 1) The server is not binding explicitly to a set of addresses using the # "bind" directive. # are explicitly listed using the "bind" directive. 密码 [root@node1 ~]# cat /etc/redis.conf | grep requirepass # If the master is password protected (using the "requirepass" configuration requirepass 123456
启动服务并登录测试redis
[root@node1 ~]# systemctl start redis [root@node1 ~]# netstat -lntup | grep redis tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 2139/redis-server 0 # 不加密码登录(没有权限执行指令) [root@node1 ~]# redis-cli 127.0.0.1:6379> KEYS * (error) NOAUTH Authentication required. 127.0.0.1:6379> # 添加密码登录 [root@node1 ~]# redis-cli -a 123456 127.0.0.1:6379> KEYS * (empty list or set) 127.0.0.1:6379>
安装JDK
[root@node1 ELK]# yum -y install java-1.8.0-openjdk
redis也是可以了 结束redis部署
5. elasticsearch集群部署
下面的设置安装源在整个环境的所有环境都要执行
# 添加ELK的yum源 [root@node2 ~]# rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch [root@node2 ~]# vim /etc/yum.repos.d/elasticsearch.repo [elasticsearch-6.x] name=Elasticsearch repository for 6.x packages baseurl=https://artifacts.elastic.co/packages/6.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md # 安装jdk和elasticsearch(这里需要注意的是jdk一定是1.8.0以上的版本) [root@node2 ~]# yum -y install java-1.8.0-openjdk
在192.168.176.130、131、132 机器上执行
[root@node1 ~]# yum -y install elasticsearch [root@node2 ~]# yum -y install elasticsearch [root@node3 ~]# yum -y install elasticsearch
温馨提示：以上安装要在三台机器上都要执行
配置文件修改
温馨提示：三台机器上都要修改配置文件
三台机器配置文件的不同之处
node.name: 这里的名称每台机器都不能一样 network.host: 这里是本服务器的地址

启动elasticsearch服务
温馨提示：三台机器都要启动(elasticsearch监听的端口是9200和9300)
[root@node2 ELK]# systemctl start elasticsearch [root@node3 ELK]# systemctl start elasticsearch [root@node4 ELK]# systemctl start elasticsearch
检查elasticsearch集群
elasticsearch 采用的是接口的方式去查看数据和状态信息
# 查看集群状态 [root@node2 ELK]# curl -X GET "192.168.176.130:9200/_cat/health?v" epoch timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent 1542525784 07:23:04 elk-cluster green 3 3 0 0 0 0 0 0 - 100.0% # 查看集群性能 [root@node2 ELK]# curl -X GET "192.168.176.130:9200/_cat/nodes?v" ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 192.168.176.131 26 96 2 0.05 0.07 0.05 mdi * node-2 192.168.176.132 26 96 3 0.06 0.06 0.05 mdi - node-3 192.168.176.130 25 95 0 0.00 0.02 0.05 mdi - node-1
安装elasticsearch的可视化web工具
温馨提示：只在一台机器上安装即可
[root@node2 ELK]# yum -y install epel-release
[root@node2 ELK]# yum -y install git
[root@node2 ELK]# yum -y install nodejs
git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install
npm run start
6. logstash安装
这个环境中我们有两台服务器需要安装logstash 一个收集数据放到redis一个在redis中读放大elasticsearch中
192.168.176.128 这台机器负责收集并写到redis
192.168.176.129 这台机器负责读redis数据写的elasticsearch中
在两台机器上安装logstash
[root@manager ~]# yum -y install logstash [root@node1 ~]# yum -y install logstash 检查安装是否成功(检查版本) [root@manager ELK]# /usr/share/logstash/bin/logstash --version logstash 6.5.0 [root@node1 ELK]# /usr/share/logstash/bin/logstash --version logstash 6.5.0
在192.168.176.128服务器编写配置logstash收集并存入redis的配置文件
# 这个文件不存在，需要自己编辑
[root@manager ELK]# cat /etc/logstash/conf.d/logstash-to-redis.conf
input {
file {
path => ["/var/log/nginx/access.log"]
type => "nginx-access"
tags => ["nginxlog","test"]
start_position => "beginning"
}
}
filter {
}
output {
redis {
host => ["192.168.176.129"]
password => "123456"
db => "0"
data_type => "list"
key => "nginxlog"
}
}
这里的配置文件就不解释了，elasticsearch的具体参数介绍请看：elasticsearch详解

上的输出表示启动成功，下面还会输出一些数据
这些就是我们的日志数据，在redis里面读出来的一个debug信息
我们查看129中的redis是不是已经空了
[root@node1 ~]# redis-cli -a 123456 127.0.0.1:6379> LLEN nginxlog (integer) 11 127.0.0.1:6379> LLEN nginxlog (integer) 0 127.0.0.1:6379>
查看elasticsearch里面是不是多出来一个索引
[root@node2 elasticsearch-head-master]# curl "192.168.176.130:9200/_cat/indices?v" health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open bank kk8k6Y8eRCWiLDR3fBCoHA 5 1 1000 0 958.1kb 475.1kb green open nginxlogs-2018.11.18 IocfOyAIT4-cxC-7O9kMtw 5 1 11 0 72.1kb 36kb
这里的nginxlogs-2018.11.18索引nginx的日志数据
接下了就用kibana展示出啦
7. kibana安装
在192.168.176.133的服务器上安装kibana
[root@node5 ~]# yum -y install kibana # 查看是否安装成功(查看版本) [root@node5 ELK]# /usr/share/kibana/bin/kibana --version 6.5.0
编辑kibana的配置文件
需要修改的地方：
# 监听端口 server.port：5601 去掉注释即可 # 监听地址 server.host: "localhost" 去掉注释修改为 server.host: "0.0.0.0" # elasticsearch地址 elasticsearch.url: "http://localhost:9200" 去掉注释修改为 elasticsearch.url: "http://192.168.176.130:9200"
