tidb測試環境安裝，離線部署
1.環境以及規劃
機器:centos7.5 ; 檔案系統為ext4；記憶體16g；cpu8核，共三個節點；
ip hostname roles 10.40.20.66 vm-10-40-20-66 tidb tipd tikv 10.40.20.67 vm-10-40-20-67 tidb tipd tikv 10.40.20.92 vm-10-40-20-92 tipd tikv
2 .本地下載tidb-ansible-master.zip，上傳到中控機，然後重新命名為tidb-ansible;
3.安裝ansible：
sudo yum -y install python-pip curl
sudo yum -y install sshpass
cd tidb-ansible
sudo pip install -r requirements.txt
sudo pip install -r requirements.txt會報錯缺少依賴包，去http://mirrors.aliyun.com/pypi/simple/映象去下載python依賴包：
Jinja2-2.9.6.tar.gz；jmespath-0.9.1.tar.gz；MarkupSafe-0.23.tar.gz ，注意版本依賴;
4.建立tidb使用者，設定免密碼登入，配ntp同步；
ansible -i hosts.ini all -m shell -a "ntpstat" -b ansible -i hosts.ini all -m shell -a "ntpq -p" -b
5.編輯host.ini:
[tidb@vm-10-40-20-66:~/tidb-ansible]$ cat hosts.ini [servers] 10.40.20.66 10.40.20.67 10.40.20.92 [all:vars] username = tidb ntp_server = pool.ntp.org
6.編輯invertory.ini:
## TiDB Cluster Part [tidb_servers] 10.40.20.66 10.40.20.67 [tikv_servers] 10.40.20.66 10.40.20.67 10.40.20.92 [pd_servers] 10.40.20.66 10.40.20.67 10.40.20.92 [spark_master] [spark_slaves] ## Monitoring Part # prometheus and pushgateway servers [monitoring_servers] 10.40.20.66 [grafana_servers] 10.40.20.66 # node_exporter and blackbox_exporter servers [monitored_servers] 10.40.20.66 10.40.20.67 10.40.20.92 [alertmanager_servers] 10.40.20.66 [kafka_exporter_servers] ## Binlog Part [pump_servers:children] tidb_servers [drainer_servers] ## Group variables [pd_servers:vars] # location_labels = ["zone","rack","host"] ## Global variables [all:vars] deploy_dir = /data/tidb/deploy ## Connection # ssh via normal user ansible_user = tidb cluster_name = leochen-cluster tidb_version = v2.0.7 # process supervision, [systemd, supervise] process_supervision = systemd timezone = Asia/Shanghai enable_firewalld = False # check NTP service enable_ntpd = True set_hostname = False ## binlog trigger enable_binlog = False # zookeeper address of kafka cluster for binlog, example: # zookeeper_addrs = "192.168.0.11:2181,192.168.0.12:2181,192.168.0.13:2181" zookeeper_addrs = "" # kafka cluster address for monitoring, example: # kafka_addrs = "192.168.0.11:9092,192.168.0.12:9092,192.168.0.13:9092" kafka_addrs = "" # store slow query log into seperate file enable_slow_query_log = False # enable TLS authentication in the TiDB cluster enable_tls = False # KV mode deploy_without_tidb = False # Optional: Set if you already have a alertmanager server. # Format: alertmanager_host:alertmanager_port alertmanager_target = "" grafana_admin_user = "admin" grafana_admin_password = "admin" ### Collect diagnosis collect_log_recent_hours = 2 enable_bandwidth_limit = True # default: 10Mb/s, unit: Kbit/s collect_bandwidth_limit = 10000
7.安裝tidb叢集：
安裝前檢驗 執行以下命令如果所有 server 返回 tidb 表示 ssh 互信配置成功。 ansible -i inventory.ini all -m shell -a 'whoami' 執行以下命令如果所有 server 返回 root 表示 tidb 使用者 sudo 免密碼配置成功。 ansible -i inventory.ini all -m shell -a 'whoami' -b
下載安裝包，上傳到downloads目錄：
[tidb@vm-10-40-20-66:~/tidb-ansible/downloads]$ ll total 565468 -rw-r--r-- 1 tidb tidb 9631079 Nov 1 17:08 alertmanager-0.14.0.tar.gz -rw-r--r-- 1 tidb tidb 4950085 Nov 1 17:08 blackbox_exporter-0.12.0.tar.gz -rw-r--r-- 1 tidb tidb 2125503 Nov 1 17:08 fio-3.8.tar.gz -rw-r--r-- 1 tidb tidb 47187988 Nov 1 17:08 grafana-4.6.3.tar.gz -rw-r--r-- 1 tidb tidb 3124144 Nov 1 17:08 grafana_collector-latest.tar.gz -rw-r--r-- 1 tidb tidb 3940228 Nov 1 17:08 kafka_exporter-1.1.0.tar.gz -rw-r--r-- 1 tidb tidb 5278094 Nov 1 17:08 node_exporter-0.15.2.tar.gz -rw-r--r-- 1 tidb tidb 26438285 Nov 1 17:08 prometheus-2.2.1.tar.gz -rw-r--r-- 1 tidb tidb 3723718 Nov 1 17:08 pushgateway-0.4.0.tar.gz -rw-r--r-- 1 tidb tidb 201142612 Nov 1 17:08 spark-2.1.1-bin-hadoop2.7.tgz -rw-r--r-- 1 tidb tidb 45854140 Nov 1 17:08 tidb-binlog-latest.tar.gz -rw-r--r-- 1 tidb tidb 3551289 Nov 1 17:08 tidb-insight.tar.gz -rw-r--r-- 1 tidb tidb 43271878 Nov 1 17:08 tidb-tools-latest.tar.gz -rw-r--r-- 1 tidb tidb 156970586 Nov 1 17:08 tidb-v2.0.7.tar.gz -rw-r--r-- 1 tidb tidb 18878689 Nov 1 17:08 tispark-latest.tar.gz -rw-r--r-- 1 tidb tidb 2937369 Nov 1 17:08 tispark-sample-data.tar.gz
8.編輯bootstrap.yml檔案，不符合的可以暫時註釋掉，測試環境機器配置不高；
9.ansible-playbook bootstrap.yml；
10.ansible-playbook deploy.yml；
11.ansible-playbook start.yml；
12 . 使用 MySQL 客戶端連線測試，TCP 4000 埠是 TiDB 服務預設埠。
[[email protected]:~/tidb-ansible/downloads]$ mysql -u root -h 10.40.20.66 -P 4000
