Tars--------企業級入門實踐篇

背景

上一篇詳細介紹了Tars的背景、優點與架構等信息，本篇繼續介紹Tars安裝過程。
注：本篇採用CentOS 7(7.6)系統

安裝MySql

這裏推薦mysql5.6或者5.7版本的二進制包安裝方式。
本次採用5.7版本安裝，MySQL5.6安裝方式查看歷史MySQL安裝篇幅。
經測試，在安裝8.0版本的MySQL，在後續沒法成功編譯TarsFramework。

• 切換工做路徑至/usr/local/src

  [root@lisea ~]# cd /usr/local/src/

• 下載MySQL

  [root@lisea src]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.25-linux-glibc2.12-x86_64.tar

• 解壓 MySQL 5.7 二進制包

  [root@lisea src]# tar xf mysql-5.7.25-linux-glibc2.12-x86_64.tar
  [root@lisea src]# tar xf mysql-5.7.25-linux-glibc2.12-x86_64.tar.gz

• 移動 解壓好的MySQL 5.7目錄至/usr/local

  [root@lisea src]# mv mysql-5.7.25-linux-glibc2.12-x86_64 /usr/local

• 建立MySQL軟鏈接

  [root@lisea src]# ln -s /usr/local/mysql-5.7.25-linux-glibc2.12-x86_64 /usr/local/mysql

• 建立 mysql 應用運行用戶

  [root@lisea src]# useradd -r -s /sbin/nologin mysql

• 建立 MySQL 數據存放目錄

  [root@lisea src]# mkdir -vp /data/mysql_data
  mkdir: created directory `/data'
  mkdir: created directory `/data/mysql_data'

• 在 MySQL 二進制包目錄中建立 mysql-files 目錄 [MySQL 數據導入/導出數據專放目錄]

  [root@lisea src]# mkdir -v /usr/local/mysql/mysql-files
  mkdir: created directory `/usr/local/mysql/mysql-files'

• 修改 MySQL 二進制包目錄的所屬用戶與所屬組

  [root@lisea src]# chown root.mysql -R /usr/local/mysql-5.7.25-linux-glibc2.12-x86_64

• 修改 MySQL 數據目錄與 數據導入/導出專放目錄的所屬用戶與所屬組

  [root@lisea src]# chown mysql.mysql /usr/local/mysql/mysql-files /data/mysql_data

• 重命名不使用系統自帶 MySQL 配置文件 /etc/my.cnf [ debian類系統在 /etc/mysql/my.cnf ]

  [root@lisea src]# mv /etc/my.cnf{,.old}

• 初始化

  [root@lisea src]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql_data
  2019-02-03T13:56:34.415131Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

  2019-02-03T13:56:35.926081Z 1 [Note] A temporary password is generated for root@localhost: wKoMdt7<yNor

• 開啓 SSL 鏈接[可選]

  [root@lisea src]# /usr/local/mysql/bin/mysql_ssl_rsa_setup -d /data/mysql_data

• 修改SSL證書文件所屬用戶和用戶組

  [root@lisea src]# chown mysql.mysql -R /data/mysql_data

• 建立mysql systemctl啓動腳本[因爲博客markdown語法支持問題，沒法展現腳本內容，參考MySQL8.0啓動腳本]

  [root@lisea src]# cat /usr/lib/systemd/system/mysqld.service

• systemd加載啓動配置文件

  [root@lisea src]#  systemctl daemon-reload

• 建立MySQL配置文件my.cnf, 指定數據目錄

  [root@lisea src]# cat /etc/my.cnf
  [mysqld]
  user = mysql
  bind_address = 0.0.0.0
  character_set_server=utf8mb4
  skip_name_resolve = 1
  max_connections = 800
  max_connect_errors = 1000
  datadir = /data/mysql_data

• 啓動MySQL服務

  [root@lisea src]# systemctl start mysqld

• 添加MySQL bin目錄至path變量，並生效環境變量

  [root@lisea src]# cat /etc/profile.d/mysql.sh 
  export MYSQL_HOME=/usr/local/mysql
  export PATH=$MYSQL_HOME/bin:$PATH

[root@lisea src]# source /etc/profile

* 經過mysql命令鏈接mysql服務，並修改默認密碼(本次修改成123)， 默認密碼爲初始化時的隨機密碼
```bash
[root@lisea src]# mysql -uroot -p'wKoMdt7<yNor'
mysql> set password = '123';
Query OK, 0 rows affected (0.00 sec)

tars安裝

• 下載TarsFramework源碼

  [root@lisea src]# git clone https://github.com/TarsCloud/TarsFramework.git
  Cloning into 'TarsFramework'...
  remote: Enumerating objects: 20, done.
  remote: Counting objects: 100% (20/20), done.

  Resolving deltas: 100% (174/174), done.

• TarsFramework編譯

  [root@lisea src]# cd TarsFramework/build/
  [root@lisea build]# chmod u+x build.sh
  [root@lisea build]# ./build.sh prepare
  [root@lisea build]# ./build.sh all

tars數據庫初始化

• 注意將${your machine ip}改成部署機器的IP
• 若是exec-sql.sh腳本執行出錯，須要腳本里修改數據庫用戶名root對應的密碼
• 腳本執行後，會建立3個數據庫，分別是db_tars、tars_stat、tars_property。
  • db_tars是框架運行依賴的核心數據庫，裏面包括了服務部署信息、服務模版信息、服務配置信息等等；
  • tars_stat是服務監控數據存儲的數據庫；
  • tars_property是服務屬性監控數據存儲的數據庫；
• 添加數據庫用戶

  mysql> grant all on *.* to 'tars'@'%' identified by 'tars2015' with grant option;
  Query OK, 0 rows affected, 1 warning (0.08 sec)
  mysql> grant all on *.* to 'tars'@'localhost' identified by 'tars2015' with grant option;
  Query OK, 0 rows affected, 2 warnings (0.00 sec)
  mysql> grant all on *.* to 'tars'@'172.21.0.15' identified by 'tars2015' with grant option;         
  Query OK, 0 rows affected, 1 warning (0.00 sec)

• 修改部署數據庫的腳本ip信息[sql腳本在framework/sql目錄下，修改部署的ip信息]
  注：172.21.0.15是測試環境地址，修改爲大家本地地址便可。

  [root@lisea build]# cd ../sql
  [root@lisea sql]# sed -i "s/192.168.2.131/172.21.0.15/g" `grep 192.168.2.131 -rl ./*`                  
  [root@lisea sql]# sed -i "s/db.tars.com/172.21.0.15/g" `grep db.tars.com -rl ./*`                  
  [root@lisea sql]# sed -i "s/10.120.129.226/172.21.0.15/g" `grep 10.120.129.226 -rl ./*`

• 修改exec-sql.sh文件數據庫root密碼

  [root@lisea sql]# cat exec-sql.sh 
  mysql -uroot -p123 -e "create database db_tars"
  mysql -uroot -p123 -e "create database tars_stat"
  mysql -uroot -p123 -e "create database tars_property"
  mysql -uroot -p123 -e "create database db_tars_web"
  mysql -uroot -p123 db_tars < db_tars.sql

• 建立數據庫

  [root@lisea sql]# chmod u+x exec-sql.sh
  [root@lisea sql]# ./exec-sql.sh
  mysql: [Warning] Using a password on the command line interface can be insecure.
  mysql: [Warning] Using a password on the command line interface can be insecure.

tars框架運行環境搭建

框架服務的安裝分兩種：

• 一種是核心基礎服務(必須的)，必須手工部署的，
  • tarsAdminRegistry
  • tarsregistry
  • tarsnode
  • tarsconfig
  • tarspatch
• 一種是普通基礎服務(可選的)，能夠經過管理平臺發佈的(和普通服務同樣）。
  • tarsstat
  • tarsproperty
  • tarsnotify
  • tarslog
  • tarsquerystat
  • tarsqueryproperty
• 準備核心基礎服務安裝包
  會在當前目錄生成framework.tgz 包 這個包包含了 tarsAdminRegistry, tarsregistry, tarsnode, tarsconfig, tarspatch 部署相關的文件

  [root@lisea sql]# cd ../build/
  [root@lisea build]# make framework-tar

• 普通基礎服務安裝包準備[可選]
  生成的發佈包，在管理平臺部署發佈完成後

  [root@lisea build]# make tarsstat-tar
  [root@lisea build]# make tarsnotify-tar
  [root@lisea build]# make tarsproperty-tar
  [root@lisea build]# make tarslog-tar
  [root@lisea build]# make tarsquerystat-tar
  [root@lisea build]# make tarsqueryproperty-tar

  安裝核心基礎服務

• 建立基礎服務的工做目錄

  [root@lisea build]# mkdir -vp /usr/local/app/tars
  mkdir: created directory ‘/usr/local/app’
  mkdir: created directory ‘/usr/local/app/tars’

• 將已打好的框架服務包複製到/usr/local/app/tars/，並解壓

  [root@lisea build]# cp framework.tgz /usr/local/app/tars/
  [root@lisea build]# cd /usr/local/app/tars
  [root@lisea tars]# tar xf /usr/local/app/tars/framework.tgz

• 修改各個服務對應conf目錄下配置文件，注意將配置文件中的ip地址修改成本機ip地址

  [root@lisea tars]# cd /usr/local/app/tars
  [root@lisea tars]# sed -i "s/192.168.2.131/172.21.0.15/g" `grep 192.168.2.131 -rl ./*`                  
  [root@lisea tars]# sed -i "s/db.tars.com/172.21.0.15/g" `grep db.tars.com -rl ./*`                               
  [root@lisea tars]# sed -i "s/registry.tars.com/172.21.0.15/g" `grep registry.tars.com -rl ./*`                  
  [root@lisea tars]# sed -i "s/web.tars.com/172.21.0.15/g" `grep web.tars.com -rl ./*`

• 啓動tars框架服務

  [root@lisea tars]# chmod u+x tars_install.sh 
  [root@lisea tars]# ./tars_install.sh

• 部署管理平臺並啓動web管理平臺(管理平臺必須和tarspatch部署在同一臺服務器上)部署tarspatch
  看看rsync進程是否起來了，若沒有看看rsync使用的配置中的ip是否正確（即把web.tars.com替換成本機ip)

  [root@lisea tars]# tarspatch/util/init.sh

• tarsnode配置crontab監控[可選]

  * * * * * /usr/local/app/tars/tarsnode/util/monitor.sh

  安裝web管理系統

• 下載tars-web

  [root@lisea tars]# cd /usr/local/app
  [root@lisea app]# git clone https://github.com/TarsCloud/TarsWeb.git

• 修改配置文件，將配置文件中的ip地址修改成本機ip(172.21.0.15)地址

  [root@lisea app]# cd TarsWeb/
  [root@lisea TarsWeb]# sed -i 's/db.tars.com/172.21.0.15/g' config/webConf.js                  
  [root@lisea TarsWeb]# sed -i 's/registry.tars.com/172.21.0.15/g' config/tars.conf

• 安裝npm環境

  [root@lisea TarsWeb]# wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
  [root@lisea TarsWeb]# source ~/.bashrc
  [root@lisea TarsWeb]# nvm install v8.11.3
  [root@lisea TarsWeb]# npm install -g pm2 --registry=https://registry.npm.taobao.org

• 安裝web管理頁面依賴, 建立日誌目錄，啓動web

  [root@lisea TarsWeb]# npm install --registry=https://registry.npm.taobao.org
  [root@lisea TarsWeb]# mkdir -p /data/log/tars
  [root@lisea TarsWeb]# npm run prd
