zipkin|zipkin 分布式链路追踪服务端搭建 zipkin分布式链路追踪服务端搭

Cassandra集群搭建 1、下载安装包
http://archive.apache.org/dist/cassandra/3.11.6/
apache-cassandra-3.11.6-bin.tar.gz
2、确保各机器已经配置好网络IP及hostname关闭防火墙并安装好jdk8
本次安装的机器为192.168.56.111~192.168.56.116 共6台机器
3、解压apache-cassandra-3.11.6-bin.tar.gz 至/cluster/cassandra/
4、创建所需存储目录

useradd cassandra chmod 777 -R /cluster/cassandra chown -R cassandra: /cluster/cassandra/apache-cassandra-3.11.6/ su - cassandra mkdir /cluster/cassandra/data mkdir /cluster/cassandra/commitlog mkdir /cluster/cassandra/saved_caches

5、修改配置文件
vi /cluster/cassandra/apache-cassandra-3.11.6/conf/cassandra.yaml
修改 cassandra.yaml 配置文件，配置111~113为seeds。
192.168.56.111配置：

cluster_name: 'zipkin cassandra cluster' data_file_directories: -/cluster/cassandra/data commitlog_directory: /cluster/cassandra/commitlog saved_caches_directory: /cluster/cassandra/saved_caches - seeds: "192.168.56.111,192.168.56.112,192.168.56.113" listen_address: 192.168.56.111 start_rpc: true rpc_address: 192.168.56.111

192.168.56.112配置：

cluster_name: 'zipkin cassandra cluster' data_file_directories: -/cluster/cassandra/data commitlog_directory: /cluster/cassandra/commitlog saved_caches_directory: /cluster/cassandra/saved_caches - seeds: "192.168.56.111,192.168.56.112,192.168.56.113" listen_address: 192.168.56.112 start_rpc: true rpc_address: 192.168.56.112

192.168.56.113配置：

cluster_name: 'zipkin cassandra cluster' data_file_directories: -/cluster/cassandra/data commitlog_directory: /cluster/cassandra/commitlog saved_caches_directory: /cluster/cassandra/saved_caches - seeds: "192.168.56.111,192.168.56.112,192.168.56.113" listen_address: 192.168.56.113 start_rpc: true rpc_address: 192.168.56.113

192.168.56.114配置：

cluster_name: 'zipkin cassandra cluster' data_file_directories: -/cluster/cassandra/data commitlog_directory: /cluster/cassandra/commitlog saved_caches_directory: /cluster/cassandra/saved_caches - seeds: "192.168.56.111,192.168.56.112,192.168.56.113" listen_address: 192.168.56.114 start_rpc: true rpc_address: 192.168.56.114

192.168.56.115配置：

cluster_name: 'zipkin cassandra cluster' data_file_directories: -/cluster/cassandra/data commitlog_directory: /cluster/cassandra/commitlog saved_caches_directory: /cluster/cassandra/saved_caches - seeds: "192.168.56.111,192.168.56.112,192.168.56.113" listen_address: 192.168.56.115 start_rpc: true rpc_address: 192.168.56.115

192.168.56.116配置：

cluster_name: 'zipkin cassandra cluster' data_file_directories: -/cluster/cassandra/data commitlog_directory: /cluster/cassandra/commitlog saved_caches_directory: /cluster/cassandra/saved_caches - seeds: "192.168.56.111,192.168.56.112,192.168.56.113" listen_address: 192.168.56.116 start_rpc: true rpc_address: 192.168.56.116

6、linux系统文件连接数修改

vi /etc/sysctl.confvm.zone_reclaim_mode=0 vm.max_map_count = 262144 vm.swappiness = 1sysctl -pvi /etc/security/limits.conf * soft nofile 65536 * hard nofile 65536 * soft nproc 65536 * hard nproc 65536

7、启动

然后重启启动，先启动seed /cluster/cassandra/apache-cassandra-3.11.6/bin/cassandra启动完成后，可使用 /cluster/cassandra/apache-cassandra-3.11.6/bin/nodetool status 查看集群状态 [root@cassandra-1 bin]# ./nodetool status Datacenter: datacenter1 ======================= Status=Up/Down |/ State=Normal/Leaving/Joining/Moving --AddressLoadTokensOwns (effective)Host IDRack UN192.168.56.111388.77 KiB25633.6%3b9bdc01-8213-4187-b963-ebe1409abb22rack1 UN192.168.56.112238.42 KiB25631.5%49638809-0c16-46f5-b87e-002177644ab2rack1 UN192.168.56.113156.5 KiB25635.1%0fa46853-1a0a-45d0-a553-c08b05532ef1rack1 UN192.168.56.114218.69 KiB25633.0%da86ed1c-0635-4404-b948-af04e118fa42rack1 UN192.168.56.115181.74 KiB25636.1%c4498f24-09af-46ec-851b-d3d94e8e2713rack1 UN192.168.56.116187.38 KiB25630.8%29efd6eb-2a46-43ea-93f9-169745201f99rack1[cassandra@cassandra-1 bin]$ ./cqlsh 192.168.56.111 Connected to zipkin cassandra cluster at 192.168.56.111:9042.

8、开机启动配制

vi /usr/lib/systemd/system/cassandra.service 添加以下内容[Unit] Description=Cassandra Server Service After=network.service[Service] Type=simplePIDFile=/var/run/cassandra.pid #新建一个用户和用户组，Cassandra无法使用root账号启动 User=cassandra #Group=cassandra #此处为Cassandra包解压后的路径 ExecStart=/cluster/cassandra/apache-cassandra-3.11.6/bin/cassandra -f -p /var/run/cassandra.pid StandardOutput=journal StandardError=journal LimitNOFILE=100000 LimitMEMLOCK=infinity LimitNPROC=32768 LimitAS=infinity[Install] WantedBy=multi-user.target#更新 systemctl systemctl daemon-reload # 设置为开机启动 systemctl enable cassandra

【zipkin|zipkin 分布式链路追踪服务端搭建】在cassandra执行以下脚本
https://github.com/openzipkin/zipkin/tree/master/zipkin-storage/cassandra/src/main/resources
zipkin服务端搭建 1、创建服务器目录

mkdir /cluster cd /cluster mkdir zipkin cd zipkin

2、下载zipkin.jar
https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/2.12.9/zipkin-server-2.12.9-exec.jar
3、开机启动脚本
（zipkin用cassandra集群存储）

zipkin.sh #!/bin/bash nohup java -jar /cluster/zipkin/zipkin-server-2.12.9-exec.jar--STORAGE_TYPE="cassandra3" --CASSANDRA_CONTACT_POINTS="192.168.56.111,192.168.56.112,192.168.56.113" --rm -p 9411:9411 >/cluster/zipkin/log.txt &/etc/systemd/system/zipkin.service [Unit] Description=zipkin After=network.target [Service] Type=forking ExecStart=/cluster/zipkin/zipkin.sh PrivateTmp=true [Install] WantedBy=multi-user.target开机启动systemctl enable zipkin 启动 systemctl start zipkin
