redash 在CentOS8环境部署（非docker）
redesh Centos参考地址：
python2.7 环境：https://ld246.com/article/1519440121831
我是按python3环境 ：https://blog.csdn.net/htmljsp/article/details/126194715
一、环境准备
- 单机安装 redis
官网安装地址：
https://redis.io/docs/getting-started/installation/install-redis-from-source/
选择按源码编译安装
wget https://download.redis.io/redis-stable.tar.gz安装C++编译环境、make
yum -y install gcc automake autoconf libtool make
##验证成功
whereis make错误：configure: error: no acceptable C compiler found in $PATH
解决：需要按照C++编译环境
To compile Redis, first the tarball, change to the root directory, and then run make:
tar -xzvf redis-stable.tar.gz
cd redis-stable
make结果输出：
......
CC redis-cli.o
CC redisassert.o
CC cli_common.o
LINK redis-cli
CC redis-benchmark.o
LINK redis-benchmark
INSTALL redis-check-rdb
INSTALL redis-check-aof
Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory '/var/tools/redis-stable/src'
-----------------------------------------------------------
make之后，会在src目录下增加两个目录：
-rwxr-xr-x 1 root root 7237624 Jan 11 04:09 redis-cli
... ...
-rwxr-xr-x 1 root root 14403144 Jan 11 04:09 redis-server
redis-server: the Redis Server itself
redis-cli is the command line interface utility to talk with Redis.
To install these binaries in /usr/local/bin, run:
make install
结果输出：
cd src && make install
make[1]: Entering directory '/var/tools/redis-stable/src'

测试安装成功：
redis-cli -h 127.0.0.1 -p 6379

OK
127.0.0.1:6379> get a1

127.0.0.1:6379>- 安装 PostgreSQL 数据库
安装
# Install the repository RPM:
sudo dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm# Disable the built-in PostgreSQL module:
sudo dnf -qy module disable postgresql# Install PostgreSQL:
sudo dnf install -y postgresql15-server
初始化
# Optionally initialize the database and enable automatic start:
sudo /usr/pgsql-15/bin/postgresql-15-setup initdb
sudo systemctl enable postgresql-15
sudo systemctl start postgresql-15配置
postgresql.conf
安装后路径：/var/lib/pgsql/15，修改配置文件
vi /var/lib/pgsql/15/data/postgresql.conf
#增加一行：
listen_addresses = '*'
pg_hba.conf
配置文件修改：
/var/lib/pgsql/15/data
pg_hba.conf 添加
host all all 0.0.0.0/0 md5
host replication all 0.0.0.0/0 md5设置用户密码
PostgreSQL会创建一个默认的linux用户postgres和一个数据库用户postgres,修改pg数据库帐号密码
注：后来思考，如有pg上已经有了postgres库及用户，会与存在的系统冲突；尝试新建用户redash及数据库redash，增强兼容性。
#通过su命令切换linux用户为postgres会自动进入命令行
su postgres
#启动SQL Shell
psql
#修改密码
ALTER USER postgres WITH PASSWORD 'NewPassword';如：
[root@localhost ~]# su postgres
bash-4.4$ psql
could not change directory to "/root": Permission denied
psql (15.1)
Type "help" for help.
postgres=# ALTER USER postgres WITH PASSWORD 'NewPassword';
psql基础知识点：
另一种登录方式：
在root帐号：
psql -h192.168.85.131 -U postgres#类似show databases；
\l 或 select datname from pg_database;
#切换数据库
\c 数据库名
#类似show tables
\dt 或SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';
#describe table_name;
\d tablename或 SELECT column_name FROM information_schema.columns WHERE table_name ='table_name';
重置linux用户postgres密码
#在root帐号下，删除postgres密码
passwd -d postgres
#设置新密码
sudo -u postgres passwd
sys- python环境
安装python隔离
yum install python3-pip
pip3 install virtualenv
#测试
virtualenv --version验证
进入隔离环境

- 安装redash
下载源码
yum install git
git clone https://github.com/getredash/redash.git创建项目虚拟环境
#先创建存储虚拟环境的独立目录
cd /var
mkdir -p py_virtual
python3 -m venv env_redash
注意：在py_virtual下生成一个目录 env_redash，下次启动虚拟环境时，进入这个目录，启动
#激活环境
source env_redash/bin/activate#可选，配置进入虚拟环境的快捷命令,在文件末尾增加一行,以后键入to_env_redash可以在任意目录进入虚拟环境
vi /etc/profile
alias to_env_redash='cd /var/py_virtula && source env_redash/bin/activate'
source /etc/profile安装依赖包
-----------------------
注意：这块会因为网络延迟高反复报timeout错误，我是将反复下载不下来的包，在requirement txt文件进行#号注释，回头下载
requirements.txt 我注释了passlib 、psycopg2-2.8.3,这两个包手工解决,下面有操作。
requirements_all_ds 我只保留了3个package：pymssql, pyhive, mysqlclient：Successfully installed mysqlclient-1.3.14 pyhive-0.6.1 pymssql-2.1.4
如果全部安装会卡住：
Getting requirements to build wheel ...\ 之后无反应，暂时没有定位原因
#配置pip国内镜像，进入用户目录
cd ~
mkdir .pip
cd .pip
vi pip.conf

pip install saslpip install thrift
pip install thrift-sasl编译
npm install --legacy-peer-deps
##将路径切换到redash根目录，否则执行编译安装，会报下面问题；--legacy-peer-deps保证本地package版本与远程版本不一致时，保留本地版本
(env_redash) [root@localhost redash]# npm install --legacy-peer-deps
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /usr/include/package.json
npm ERR! errno -2

npm ERR! enoentnpm ERR! A complete log of this run can be found in:
npm ERR! /root/.npm/_logs/2023-01-13T02_02_28_162Z-debug-0.log
解决：运行目录需要在redash根目录上，与package.json在一个位置查看yarn是否被安装且镜像要设置国内
yarn -v
如果没有安装，参考下面问题解决方式

配置
前端这边不得不提一点，redash 项目前后端分离。中间依托了前端 node 的一个叫 dev-server 的服务器用于转发前后端请求。所以当我们在访问 redash 的时候其实请求会先打到 node 服务器那边然后再由 node 的服务器进行转发到后端 flask 服务器。
这里因为我只打算在入口的位置来配置 nginx 服务器，并不打算在 redash 服务器这边再用 nginx 转发一下。所以这里我需要配置 redash 的 node 服务器去监听 0.0.0.0 所有范围的8080 端口。8080端口是默认的所以我修改了 node 里面的 webpack.config.js 配置指定让 devServer 监听 0.0.0.0 地址。
服务器端部分其实有很多值得注意的地方。首先 readsh 给我们的默认配置是默认我们刚才将那些组件都安装在了同一台机器上面，否则你就必须面临一个重新配置相关配置参数的局面。好在 redash 将配置文件的修改放在了还算清晰的地方。
如果你没有在代码里面添加 .env 文件，所有后端服务启动的时候会默认去读取环境变量中的配置。如果环境变量里面没有配置相关的参数，那么将会直接使用所有参数的默认值加载。
redash 的配置写在 -> redash/redash/settings/__init__.py 中，这里囊括了所有的配置。如果使用环境变量的配置要到这里来这里参考 key 的名称。
redash目录：/var/tools/redash
webpack.config.js
#localhost改成127.0.0.1，linux会把localhost解析成ipv6，导致前端请求在后台代理转发时，找不到ip
const redashBackend = process.env.REDASH_BACKEND || "http://127.0.0.1:5000";devServer: {
##增加hosthost: '0.0.0.0',
... ...proxy: [{context: ["/login","/logout","/invite","/setup","/status.json","/api","/oauth"],target: redashBackend + "/",changeOrigin: true,##################################false 改成truesecure: false},{context: path => {// CSS/JS for server-rendered pages should be served from backendreturn /^\/static\/[a-z]+\.[0-9a-fA-F]+\.(css|js)$/.test(path);},target: redashBackend + "/",changeOrigin: true,secure: false}package.json
在start 行末尾增加 --disableHostCheck=true，在后续启动node运行npm run start时，会运行这段代码
"scripts": {"start": "npm-run-all --parallel watch:viz webpack-dev-server --disableHostCheck=true",redash/settings/__init__.py
配置redis地址：我是本地redis，不用动
_REDIS_URL = os.environ.get("REDASH_REDIS_URL", os.environ.get("REDIS_URL", "redis://localhost:6379/0")
)配置redash数据库地址：指向postgres地址
SQLALCHEMY_DATABASE_URI = os.environ.get("REDASH_DATABASE_URL", os.environ.get("DATABASE_URL", "postgresql://用户名:密码@192.168.16.43/数据库")
)配置加密key，key值随机生成
python -c 'import secrets; print(secrets.token_hex())'结果输出：
#用于设置REDASH_COOKIE_SECRET
(env_redash) [root@localhost redash]# python -c 'import secrets; print(secrets.token_hex())'

解决：
此时！！！需要有一个github上的账号（我用我的跟人帐号登录）官网：https://github.com/
首先，在命令行创建公密钥，一路回车即可
ssh-keygen -t rsa
cat /root/.ssh/id_rsa.pub #公钥，将以下内容加入 github 的 key然后，登录https://github.com/，界面选择Settings --> SSH and GPG keys -->new SSH keys；

问题：
error redash-client@11.0.0-dev: The engine "node" is incompatible with this module. Expected version "^14.16.1"
... ..
error:0308010C:digital envelope routines::unsupported
分析：当前安装的node版本是18，产生版本冲突，因为 node.js V17版本中最近发布的OpenSSL3.0, 而OpenSSL3.0对允许算法和密钥大小增加了严格的限制
参考https://www.pudn.com/news/633d4b902aaf6043c9ecf2a2.html
解决1：不卸载当前版本，增加设置,我选的方法
yarn config set ignore-engines true#临时设置：
export NODE_OPTIONS=--openssl-legacy-provider
#永久设置：
vi /etc/profile
export NODE_OPTIONS="--openssl-legacy-provider"
source /etc/profile解决2：重装14.x或16.x，没有实测过
root帐号运行：
curl -fsSL https://rpm.nodesource.com/setup_16.x | sudo bash -
curl -fsSL https://rpm.nodesource.com/setup_14.x | bash -
问题：运行 bin/run ./manage.py check-settings，
报错误：ModuleNotFoundError: No module named 'pystache'
ModuleNotFoundError: No module named 'passlib'
分析：在配置python虚拟环境时，安装requirement.txt引用的包时，注释了pystache，passlib
解决：安装
pip install pystache==0.5.4
pip install passlib==1.7.1
问题：安装pystache，error in pystache setup command: use_2to3 is invalid.
分析：
后面看这个项目的描述，原来是一个中文分词的库，一开始是用C++写的并提供给Ruby用的，后面作者又写了python的接口，不过支持的版本一直在python 2.5+，于是在python3的版本进行安装的时候，会在setuptools里的setup函数里增加一个use_2to3=True的参数进行转换。
但是setuptools>=58的版本是不支持这个参数了（黑人问号），于是需要把版本降低，小于58的最后一个版本是57.5.0，pip降一下就可以了
解决：
pip install setuptools==57.5.0
pip install pystache==0.5.4问题：/var/py_virtual/env_redash/lib64/python3.6/site-packages/psycopg2/__init__.py:144: UserWarning: The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: <http://initd.org/psycopg/docs/install.html#binary-install-from-pypi>.
解决：
pip install psycopg2-binary==2.8.3问题：[HPM] Error occurred while trying to proxy request /login?next=/ from 192.168.85.131:8080 to http://localhost:5000/ (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
分析：这个问题困扰我整整两天时间
原因是就是前端请求与后端服务监听的IP地址不一致，造成前端请求无法发送到争取的IP地址和端口。
npm run start启动之后，初始化的proxy target地址是localhost:5000
#webpack.config.js
const redashBackend = process.env.REDASH_BACKEND || "http://localhost:5000";
这里的localhost在执行npm run start时，被初始化
如下面日志
......
$ babel src --out-dir lib --source-maps --ignore 'src/**/*.test.js' --copy-files --no-copy-ignored --extensions .ts,.tsx,.js,.jsx --watch
[HPM] Proxy created: ['/login','/logout','/invite','/setup','/status.json','/api','/oauth'
] -> http://localhost:5000/
[HPM] Proxy created: [Function: context] -> http://localhost:5000/
... ...目前发现，这个localhost只能通过2行的位置设置，设置环境变量.env中的REDASH_BACKEND，不起作用，原因待调查。
在webpack runserver 时日志如下：
bin/run ./manage.py runserver --debugger --reload
(env_redash) [root@localhost redash]# bin/run ./manage.py runserver --debugger --reload

解决：
修改webpack.config.js
const redashBackend = process.env.REDASH_BACKEND || "http://127.0.0.1:5000";
.杀掉服务端进程包括8080端口、5000端口，然后重新运行npm run start，这时查看日志，地址已经改成127.0.0.1；
重新运行
bin/run ./manage.py runserver --debugger --reload
去浏览器请求8080端口，请求被正确转发。但这时因为没有登录，页面跳转到127.0.0.1:5000/setup.因为我在另外ip地址访问，造成页面出错
修改127.0.0.1 为192.168.85.131，顺利进入setup页面，问题解决
