kubernetes（k8s）中部署 efk Kubernetes 开发了一个 Elasticsearch 附加组件来实现集群的日志管理。这是一个 Elasticsearch、Fluentd 和 Kibana 的组合。Elasticsearch 是一个搜索引擎，负责存储日志并提供查询接口；Fluentd 负责从 Kubernetes 搜集日志，每个node节点上面的fluentd监控并收集该节点上面的系统日志，并将处理过后的日志信息发送给Elasticsearch；Kibana 提供了一个 Web GUI，用户可以浏览和搜索存储在 Elasticsearch 中的日志。从官方github仓库下载yaml文件[root@hello ~/efk]# git clone https://github.com/kubernetes/kubernetes.git [root@hello ~/efk]# kubectl create namespace logging [root@hello ~/efk]#执行所有yaml文件[root@hello ~/efk]# cd kubernetes/cluster/addons/fluentd-elasticsearch/ [root@hello ~/efk/kubernetes/cluster/addons/fluentd-elasticsearch]# kubectl apply -f ./ namespace/logging created service/elasticsearch-logging created serviceaccount/elasticsearch-logging created clusterrole.rbac.authorization.k8s.io/elasticsearch-logging created clusterrolebinding.rbac.authorization.k8s.io/elasticsearch-logging created statefulset.apps/elasticsearch-logging created configmap/fluentd-es-config-v0.2.1 created serviceaccount/fluentd-es created clusterrole.rbac.authorization.k8s.io/fluentd-es created clusterrolebinding.rbac.authorization.k8s.io/fluentd-es created daemonset.apps/fluentd-es-v3.1.1 created deployment.apps/kibana-logging created service/kibana-logging created查看pod状态：[root@hello ~]# kubectl get pod -n logging NAME READY STATUS RESTARTS AGE elasticsearch-logging-0 1/1 Running 0 2m17s elasticsearch-logging-1 1/1 Running 0 96s fluentd-es-v3.1.1-qw9dj 1/1 Running 1 (97s ago) 2m16s kibana-logging-75bd6cccf5-pskrr 1/1 Running 1 (106s ago) 2m16s [root@hello ~]# [root@hello ~]# kubectl get service -n logging NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE elasticsearch-logging ClusterIP None <none> 9200/TCP,9300/TCP 2m41s kibana-logging ClusterIP 10.68.145.186 <none> 5601/TCP 2m40s [root@hello ~]#访问 kibana[root@hello ~]# kubectl proxy --address='192.168.1.11' --port=8086 --accept-hosts='^*$' #访问 http://192.168.1.11:8086//api/v1/namespaces/logging/services/kibana-logging/proxy/创建一个index-pattern索引默认为 logstash-* 即可，之后这里会看到日志Linux运维交流社区Linux运维交流社区，互联网新闻以及技术交流。73篇原创内容公众号 https://blog.csdn.net/qq_33921750https://my.oschina.net/u/3981543https://www.zhihu.com/people/chen-bu-yun-2https://segmentfault.com/u/hppyvyv6/articleshttps://juejin.cn/user/3315782802482007https://space.bilibili.com/352476552/articlehttps://cloud.tencent.com/developer/column/93230知乎、CSDN、开源中国、思否、掘金、哔哩哔哩、腾讯云

搭建DHCP服务，实现自动分配地址 erDiagram CUSTOMER ||--o{ ORDER : places ORDER ||--|{ LINE-ITEM : contains CUSTOMER }|..|{ DELIVERY-ADDRESS : usesDHCP实现原理DHCP定义DHCP（Dynamic Host Configuration Protocol，动态主机配置协议）是一个局域网的网络协议，使用UDP协议工作。它是一种流行的Client/Server协议，一般用于为主机或者为路由器等指定相关的配置信息。DHCP服务在企业和家庭中得到了大量的应用，它能够自动分配ip地址以及一些其他的相关信息，整个过程对客户透明。DHCP分配方式自动分配方式（Automatic Allocation），DHCP服务器为主机指定一个永久性的IP地址，一旦DHCP客户端第一次成功从DHCP服务器端租用到IP地址后，就可以永久性的使用该地址。动态分配方式（Dynamic Allocation），DHCP服务器给主机指定一个具有时间限制的IP地址，时间到期或主机明确表示放弃该地址时，该地址可以被其他主机使用。手工分配方式（Manual Allocation），客户端的IP地址是由网络管理员指定的，DHCP服务器只是将指定的IP地址告诉客户端主机。DHCP工作过程DHCP客户机在启动时，会搜寻网络中是否存在DHCP服务器。如果找到，则给DHCP服务器发送一个请求。DHCP服务器接到请求后，为DHCP客户机选择TCP/IP配置的参数，并把这些参数发送给客户端。如果已配置冲突检测设置，则DHCP服务器在将租约中的地址提供给客户机之前会使用Ping测试作用域中每个可用地址的连通性。这可确保提供给客户的每个IP地址都没有被使用手动TCP/IP配置的另一台非DHCP计算机使用。根据客户端是否第一次登录网络，DHCP的工作形式会有所不同。初次登录初次登录时DHCP工作包括四个步骤1、寻找DHCP服务器当DHCP客户端第一次登录网络的时候，计算机发现本机上没有任何IP地址设定，将以广播方式发送DHCP discover发现信息来寻找DHCP服务器，即向255.255.255.255发送特定的广播信息。网络上每一台安装了TCP/IP协议的主机都会接收这个广播信息，但只有DHCP服务器才会做出响应。2、分配IP地址在网络中接收到DHCP discover发现信息的DHCP服务器就会做出响应，它从尚未分配的IP地址池中挑选一个分配给DHCP客户机，并向DHCP客户机发送一个包含分配的IP地址和其他设置的DHCP offer提供信息。3、接受IP地址DHCP客户端接受到DHCP offer提供信息之后，选择第一个接收到的提供信息，然后以广播的方式回答一个DHCP request请求信息，该信息包含向它所选定的DHCP服务器请求IP地址的内容。4、IP地址分配确认当DHCP服务器收到DHCP客户端回答的DHCP request请求信息之后，便向DHCP客户端发送一个包含它所提供的IP地址和其他设置的DHCP ack确认信息，告诉DHCP客户端可以使用它提供的IP地址。然后，DHCP客户机便将其TCP/IP协议与网卡绑定，另外，除了DHCP客户机选中的DHCP服务器外，其他的DHCP服务器将收回曾经提供的IP地址。重新登录以后DHCP客户端每次重新登录网络时，就不需要再发送DHCP discover发现信息了，而是直接发送包含前一次所分配的IP地址的DHCP request请求信息。当DHCP服务器收到这一信息后，它会尝试让DHCP客户机继续使用原来的IP地址，并回答一个DHCP ack确认信息。如果此IP地址已无法再分配给原来的DHCP客户机使用时，则DHCP服务器给DHCP客户机回答一个DHCP nack否认信息。当原来的DHCP客户机收到此DHCP nack否认信息后，它就必须重新发送DHCP discover发现信息来请求新的IP地址。1、如果客户端DHCP request 内的IP地址在服务器端没有被使用，DHCP服务器回复DHCP ACK继续使用IP。2、如果客户端DHCP request 内的IP地址在服务器端已被使用，DHCP服务器回复DHCP NACK告诉客户端IP已被使用。3、回复NACK后，重新开始DHCP初次登录时的流程更新租约DHCP服务器向DHCP客户机出租的IP地址一般都有一个租借期限，期满后DHCP服务器便会收回出租的IP地址。如果DHCP客户机要延长其IP租约，则必须更新其IP租约。DHCP客户机启动时和IP租约期限到达租约的50%时，DHCP客户机都会自动向DHCP服务器发送更新其IP租约的信息。在CentOS7上安装DHCP软件包[root@jhr-hub ~]# yum -y install dhcp [root@jhr-hub ~]# cat /etc/dhcp/dhcpd dhcpd6.conf dhcpd.conf [root@jhr-hub ~]# cat /etc/dhcp/dhcpd.conf # # DHCP Server Configuration file. # see /usr/share/doc/dhcp*/dhcpd.conf.example # see dhcpd.conf(5) man page # [root@jhr-hub ~]# [root@jhr-hub ~]# cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf cp: overwrite ‘/etc/dhcp/dhcpd.conf’? y [root@jhr-hub ~]#修改DHCP的配置文件[root@jhr-hub ~]# vim /etc/dhcp/dhcpd.conf [root@jhr-hub ~]# [root@jhr-hub ~]# [root@jhr-hub ~]# [root@jhr-hub ~]# cat /etc/dhcp/dhcpd.conf # dhcpd.conf # # Sample configuration file for ISC dhcpd # # option definitions common to all supported networks... option domain-name "example.org"; option domain-name-servers 3.7.191.1; #设置当前的IP地址有效期，单位s default-lease-time 60; #设置申请最大有效期 max-lease-time 60; # Use this to enble / disable dynamic dns updates globally. #ddns-update-style none; # If this DHCP server is the official DHCP server for the local # network, the authoritative directive should be uncommented. #authoritative; # Use this to send dhcp log messages to a different log file (you also # have to hack syslog.conf to complete the redirection). log-facility local7; # No service will be given on this subnet, but declaring it helps the # DHCP server to understand the network topology. #声明IP地址段和子网掩码 subnet 192.168.1.0 netmask 255.255.255.0 { #地址池：设置一个地址段 range 192.168.1.100 192.168.1.200; #指定网关 option routers 3.7.191.1; #获取DNS option domain-name-servers 192.168.1.1; } # This is a very basic subnet declaration. subnet 10.254.239.0 netmask 255.255.255.224 { range 10.254.239.10 10.254.239.20; option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org; } # This declaration allows BOOTP clients to get dynamic addresses, # which we don't really recommend. subnet 10.254.239.32 netmask 255.255.255.224 { range dynamic-bootp 10.254.239.40 10.254.239.60; option broadcast-address 10.254.239.31; option routers rtr-239-32-1.example.org; } # A slightly different configuration for an internal subnet. subnet 10.5.5.0 netmask 255.255.255.224 { range 10.5.5.26 10.5.5.30; option domain-name-servers ns1.internal.example.org; option domain-name "internal.example.org"; option routers 10.5.5.1; option broadcast-address 10.5.5.31; default-lease-time 600; max-lease-time 7200; } # Hosts which require special configuration options can be listed in # host statements.
