Tars--------企业级入门实践篇

背景

上一篇详细介绍了Tars的背景、优势与架构等信息，本篇继续介绍Tars安装过程。
注：本篇采用CentOS 7(7.6)系统

环境[关闭selinux和清空防火墙规则]

依赖准备

[root@lisea ~]# yum install gcc gcc-c++ -y
[root@lisea ~]# yum install bison -y
[root@lisea ~]# yum install flex -y
[root@lisea ~]# yum install cmake -y
[root@lisea ~]# yum install ncurses-devel -y
[root@lisea ~]# yum install zlib-devel -y

安装MySql

这里推荐mysql5.6或者5.7版本的二进制包安装方式。
本次采用5.7版本安装，MySQL5.6安装方式查看历史MySQL安装篇幅。
经测试，在安装8.0版本的MySQL，在后续无法成功编译TarsFramework。

• 切换工作路径至/usr/local/src

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

• 下载MySQL

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

• 解压 MySQL 5.7 二进制包

  [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

• 移动 解压好的MySQL 5.7目录至/usr/local

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

• 创建MySQL软连接

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

• 创建 mysql 应用运行用户

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

• 创建 MySQL 数据存放目录

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

• 在 MySQL 二进制包目录中创建 mysql-files 目录 [MySQL 数据导入/导出数据专放目录]

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

• 修改 MySQL 二进制包目录的所属用户与所属组

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

• 修改 MySQL 数据目录与 数据导入/导出专放目录的所属用户与所属组

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

• 重命名不使用系统自带 MySQL 配置文件 /etc/my.cnf [ debian类系统在 /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).

  2019-02-03T13:56:35.835511Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
  2019-02-03T13:56:35.915147Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 853b8efd-27bb-11e9-9c8d-52540009b76e.
  2019-02-03T13:56:35.925540Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
  2019-02-03T13:56:35.926081Z 1 [Note] A temporary password is generated for root@localhost: wKoMdt7<yNor

• 开启 SSL 连接[可选]

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

• 修改SSL证书文件所属用户和用户组

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

• 创建mysql systemctl启动脚本[由于博客markdown语法支持问题，无法展示脚本内容，参考MySQL8.0启动脚本]

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

• systemd加载启动配置文件

  [root@lisea src]#  systemctl daemon-reload

• 创建MySQL配置文件my.cnf, 指定数据目录

  [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

• 启动MySQL服务

  [root@lisea src]# systemctl start mysqld

• 添加MySQL bin目录至path变量，并生效环境变量

  [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

* 通过mysql命令连接mysql服务，并修改默认密码(本次修改为123)， 默认密码为初始化时的随机密码
```bash
[root@lisea src]# mysql -uroot -p'wKoMdt7<yNor'
mysql> set password = '123';
Query OK, 0 rows affected (0.00 sec)

tars安装

• 下载TarsFramework源码

  [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编译

  [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数据库初始化

• 注意将${your machine ip}改为部署机器的IP
• 如果exec-sql.sh脚本执行出错，需要脚本里修改数据库用户名root对应的密码
• 脚本执行后，会创建3个数据库，分别是db_tars、tars_stat、tars_property。 db_tars是框架运行依赖的核心数据库，里面包括了服务部署信息、服务模版信息、服务配置信息等等；
• tars_stat是服务监控数据存储的数据库；
• tars_property是服务属性监控数据存储的数据库；

tars框架运行环境搭建

框架服务的安装分两种：

• 一种是核心基础服务(必须的)，必须手工部署的， tarsAdminRegistry
• tarsregistry
• tarsnode
• tarsconfig
• tarspatch
