######安装redis
# yum –y install tcl gcc //安装测试依赖工具
# tar xf redis-3.2.3.tar.gz //解压至当前目录
# cd redis-3.2.3 //切换至redis源码目录
# make //编译
# make test //有可能会失败，只是看看，不用在意
# make install //安装
# mkdir /opt/redis/{db,conf} -pv //创建redis安装目录
# cp redis.conf /opt/redis/conf/ //复制配置文件至redis安装目录
# cd src
# cp redis-benchmark redis-check-aof redis-cli redis-server mkreleasehdr.sh /opt/redis/ //复制各文件至redis安装目录
# ln -sv /opt/redis/redis-cli /usr/bin/ //将redis-cli可执行文件链接至/usr/bin目录，方便在任何目录下都可直接执行`redis-cli`
# vim /opt/redis/conf/redis.conf //修改redis.conf 中的 `daemonize`为`yes`,让server以守护进程在后台执行，这一步可以不做，因为后面要执行的脚本会自动创建这个文件，且这个值会设置为`yes`
daemonize yes
make install仅仅在你的系统上安装了二进制文件，不会替你默认配置init脚本和配置文件，为了把它用在生产环境而安装它，在源码目录的utils目录下Redis为系统提供了
这样的一个脚本install_server.sh
# cd /opt/soft/redis-3.2.3/utils
# ./install_server.sh //执行sh格式的安装脚本
Welcome to the redis service installer
This script will help you easily set up a running redis server
Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] /opt/redis/conf/redis.conf
Please select the redis log file name [/var/log/redis_6379.log]
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] /opt/redis/db/6379.db
Please select the redis executable path [/usr/local/bin/redis-server]
Selected config:
Port : 6379
Config file : /opt/redis/conf/redis.conf
Log file : /var/log/redis_6379.log
Data dir : /opt/redis/db/6379.db
Executable : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

###修改 elasticsearch配置文件 存放所收集到的日志
cd /etc/elasticsearch/
vim elasticsearch.yml
cluster.name: ELK ###集群名称
node.name: node-1 ###节点编号
node.master: true
node.data: true
path.data: /ELK/data ###elasticsearch数据路径
path.logs: /ELK/logs ###elasticsearch日志路径
network.host: elk02 ###本机主机名
discovery.zen.ping.unicast.hosts: ["elk02", "elk03"] ###自动发现节点主机名
discovery.zen.minimum_master_nodes: 2
http.cors.enabled: true
http.cors.allow-origin: "*"
xpack.security.enabled: false
启动异常：ERROR: bootstrap checks failed
system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk
问题原因：因为Centos6不支持SecComp，而ES5.2.1默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动。详见 ：https://github.com/elastic/elasticsearch/issues/22899
解决方法：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面:
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
设置线程池
thread_pool:

创建ELK数据、日志存放路径
mkdir /ELK/data
mkdir /ELK/logs
chown -R elasticsearch:elasticsearch /ELK
启动服务
service elasticsearch start
启动服务之后查看/ELK/logs路径中有日志，说明服务正常
查看端口9200、9300
9200端口是API 用来连接服务的接口
9300是内部服务
PS：报错
max number of threads [1024] for user [lish] likely too low, increase to at least [2048]
解决：切换到root用户，进入limits.d目录下修改配置文件。
vi /etc/security/limits.d/90-nproc.conf
修改如下内容：
* soft nproc 1024
#修改为
* soft nproc 2048
##修改主机名，定义dns
vim /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=elk02
GATEWAY=172.25.0.254
vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.25.11.77 elk01
172.25.11.78 elk02
172.25.11.79 elk03
注：重启生效 reboot
###配置kibana
cd /etc/kibana/
vim kibana.yml
server.port: 5601 ##定义kibana端口
server.host: "172.25.11.77" ##服务主机IP
elasticsearch.url: "http://172.25.11.78:9200" ##url调取elasticsearch
elasticsearch.url: "http://172.25.11.79:9200" ##url调取elasticsearch
######启动kibana
service kibana start
查看端口是否存在
netstat -anp | grep 5601
tcp 0 0 172.25.11.77:5601 0.0.0.0:* LISTEN 8492/node
###web页面上访问
####安装elasticsearch-analysis-ik-5.0.0.zip 分词器
####安装elasticsearch-head插件
由于elasticsearch5.0版本变化较大，目前elasticsearch5.0 暂时不支持直接安装，但是head作者提供了另一种安装方法
###安装elasticsearch-head
cd /usr/share/elasticsearch
git clone git://github.com/mobz/elasticsearch-head.git
chmod -R 777 elasticsearch-head
cd elasticsearch-head/
PS:先修改license
vim package.json
"license": "Apache-2.0",
npm install --force ###安装完node就会有npm命令
cd /usr/share/elasticsearch/elasticsearch-head/node_modules/grunt/bin
./grunt server > /dev/null 2>&1 &
###安装node
node-v6.10.1-linux-x64.tar
解压
tar -xvf node-v6.10.1-linux-x64.tar
mv node-v6.10.1-linux-x64 /usr/share/elasticsearch/
vim /etc/profile
export NODE_HOME=/usr/share/elasticsearch/node-v6.10.1-linux-x64
export PATH=$PATH:$NODE_HOME/bin
source /etc/profile
cd /usr/share/elasticsearch/node-v6.10.1-linux-x64/bin/
./node -v
v6.10.1
npm -v
3.10.10
###安装grunt
######cd /usr/share/elasticsearch/elasticsearch-head
######npm install grunt-cli
grunt --version
#### 修改head目录下的Gruntfile.js配置，head默认监听127.0.0.1
vim Gruntfile.js
hostname: '*',
connect: {
server: {
options: {
port: 9100,
hostname: '*', ####修改此处
base: '.',
keepalive: true
}
}
cd _site/
vim app.js
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://172.25.11.78:9200";
####elasticsearch配置允许跨域访问
修改elasticsearch配置文件elasticsearch.yml
cd /etc/elasticsearch/
vim elasticsearch.yml
http.cors.enabled: true
http.cors.allow-origin: "*"
####重启elasticsearch，并启动node
service elasticsearch restart ###启动elasticsearch
cd /usr/share/elasticsearch/elasticsearch-head/ ###启动node
①#######node_modules/grunt/bin/grunt server > /dev/null 2>&1 &
②#######/usr/share/elasticsearch/elasticsearch-head/node_modules/grunt/bin/grunt server > /dev/null 2>&1 &
查看集群信息

172.25.11.79 10 33 0 0.00 0.02 0.00 mdi * node-2
#####安装x-pack（marvel） 进行性能监控
配置dns
vim /etc/resolv.conf
nameserver 210.73.88.1
kibana上安装server端
cd /usr/share/kibana/
bin/kibana-plugin install x-pack
es上安装agent端
cd /usr/share/elasticsearch/
bin/elasticsearch-plugin install x-pack
卸载
bin/elasticsearch-plugin remove x-pack
PS:
安装完需要重启kibana和es 默认用户名密码elastic/changeme
查看license时间 默认一个月
curl -XGET -u elastic:1qaz2wsx 'http://172.25.11.78:9200/_xpack/license'
替换license 默认密码changeme
curl -XPUT -u elastic 'http://172.25.11.78:9200/_xpack/license?acknowledge=true' -H "Content-Type: application/json" -d @zhaishaomin-fa370f7b-6eb7-4730-9b73-89b3d93471e3-v5.json
由于是基本的license，所以需要禁用安全性
vim /etc/kibana/kibana.yml
vim /etc/elasticsearch/elasticsearch.yml
xpack.security.enabled: false ####false为禁用
####安装logstash
rpm -ivh logstash-5.0.0.rpm
