zipkin 分布式鏈路追蹤服務端搭建

Cassandra集群搭建

1谢揪、下載安裝包

http://archive.apache.org/dist/cassandra/3.11.6/

apache-cassandra-3.11.6-bin.tar.gz

2、確保各機器已經(jīng)配置好網(wǎng)絡IP及hostname關(guān)閉防火墻并安裝好jdk8

本次安裝的機器為192.168.56.111~192.168.56.116 共6臺機器

3著恩、解壓apache-cassandra-3.11.6-bin.tar.gz 至/cluster/cassandra/

4洒嗤、創(chuàng)建所需存儲目錄

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箫荡、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為seeds渔隶。

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羔挡、linux系統(tǒng)文件連接數(shù)修改

vi /etc/sysctl.conf

vm.zone_reclaim_mode=0
vm.max_map_count = 262144
vm.swappiness = 1

sysctl -p

vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 65536
* hard nproc 65536

7、啟動

然后重啟啟動间唉，先啟動seed
/cluster/cassandra/apache-cassandra-3.11.6/bin/cassandra

啟動完成后绞灼，可使用
/cluster/cassandra/apache-cassandra-3.11.6/bin/nodetool status
查看集群狀態(tài)
[root@cassandra-1 bin]# ./nodetool status
Datacenter: datacenter1

8、開機啟動配制

vi /usr/lib/systemd/system/cassandra.service
添加以下內(nèi)容

[Unit]
Description=Cassandra Server Service
After=network.service

[Service]
Type=simple

PIDFile=/var/run/cassandra.pid
#新建一個用戶和用戶組呈野，Cassandra無法使用root賬號啟動
User=cassandra
#Group=cassandra
#此處為Cassandra包解壓后的路徑
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 
# 設置為開機啟動 
systemctl enable cassandra

在cassandra執(zhí)行以下腳本
https://github.com/openzipkin/zipkin/tree/master/zipkin-storage/cassandra/src/main/resources

zipkin服務端搭建

1低矮、創(chuàng)建服務器目錄

mkdir /cluster
cd /cluster 
mkdir zipkin
cd zipkin

2、下載zipkin.jar

https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/2.12.9/zipkin-server-2.12.9-exec.jar

3被冒、開機啟動腳本

（zipkin用cassandra集群存儲）

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


開機啟動systemctl enable zipkin
       啟動 systemctl start zipkin
