redash 在CentOS8环境部署（非docker）

發(fā)布時間：2024/3/26 编程问答 29 豆豆

生活随笔收集整理的這篇文章主要介紹了 redash 在CentOS8环境部署（非docker）小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

redesh Centos參考地址：

python2.7 環(huán)境：https://ld246.com/article/1519440121831

我是按python3環(huán)境：https://blog.csdn.net/htmljsp/article/details/126194715

一、環(huán)境準備

單機安裝 redis

官網(wǎng)安裝地址：

https://redis.io/docs/getting-started/installation/install-redis-from-source/

選擇按源碼編譯安裝

wget https://download.redis.io/redis-stable.tar.gz

安裝C++編譯環(huán)境、make

yum -y install gcc automake autoconf libtool make ##驗證成功 whereis make錯誤：configure: error: no acceptable C compiler found in $PATH
解決：需要按照C++編譯環(huán)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

結果輸出：
......
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，會在src目錄下增加兩個目錄：
-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 結果輸出： cd src && make install make[1]: Entering directory '/var/tools/redis-stable/src' /usr/bin/which: no python3 in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/var/jdk/bin:/root/bin) /usr/bin/which: no python in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/var/jdk/bin:/root/bin)CC Makefile.dep /usr/bin/which: no python3 in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/var/jdk/bin:/root/bin) /usr/bin/which: no python in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/var/jdk/bin:/root/bin)Hint: It's a good idea to run 'make test' ;)INSTALL redis-serverINSTALL redis-benchmarkINSTALL redis-cli make[1]: Leaving directory '/var/tools/redis-stable/src'

啟動redis：

To stop Redis, enter Ctrl-C.

測試安裝成功：

redis-cli -h 127.0.0.1 -p 6379 127.0.0.1:6379> set a1 111 OK 127.0.0.1:6379> get a1 "111" 127.0.0.1:6379>

安裝 PostgreSQL 數(shù)據(jù)庫

安裝

# 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

安裝后路徑：/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

設置用戶密碼

PostgreSQL會創(chuàng)建一個默認的linux用戶postgres和一個數(shù)據(jù)庫用戶postgres,修改pg數(shù)據(jù)庫帳號密碼

注：后來思考，如有pg上已經有了postgres庫及用戶，會與存在的系統(tǒng)沖突；嘗試新建用戶redash及數(shù)據(jù)庫redash，增強兼容性。

#通過su命令切換linux用戶為postgres會自動進入命令行 su postgres #啟動SQL Shell psql #修改密碼 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基礎知識點：

另一種登錄方式：
在root帳號：
psql -h192.168.85.131 -U postgres

#類似show databases；
\l 或 select datname from pg_database;
#切換數(shù)據(jù)庫
\c 數(shù)據(jù)庫名
#類似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用戶postgres密碼

#在root帳號下，刪除postgres密碼 passwd -d postgres #設置新密碼 sudo -u postgres passwd sys

python環(huán)境

安裝python隔離

yum install python3-pip pip3 install virtualenv #測試 virtualenv --version

驗證

進入隔離環(huán)境

source current/bin/activate 如： [root@localhost tools]# source current/bin/activate (current) [root@localhost tools]#

退出隔離環(huán)境

deactivate 如： (current) [root@localhost tools]# deactivate

安裝 nodejs 相關

可以查看node最新版本信息

安裝redash

下載源碼

yum install git git clone https://github.com/getredash/redash.git

創(chuàng)建項目虛擬環(huán)境

#先創(chuàng)建存儲虛擬環(huán)境的獨立目錄 cd /var mkdir -p py_virtual python3 -m venv env_redash 注意：在py_virtual下生成一個目錄 env_redash，下次啟動虛擬環(huán)境時，進入這個目錄，啟動 #激活環(huán)境 source env_redash/bin/activate#可選，配置進入虛擬環(huán)境的快捷命令,在文件末尾增加一行,以后鍵入to_env_redash可以在任意目錄進入虛擬環(huán)境 vi /etc/profile alias to_env_redash='cd /var/py_virtula && source env_redash/bin/activate' source /etc/profile

安裝依賴包

-----------------------

注意：這塊會因為網(wǎng)絡延遲高反復報timeout錯誤，我是將反復下載不下來的包，在requirement txt文件進行#號注釋，回頭下載

requirements.txt 我注釋了passlib 、psycopg2-2.8.3,這兩個包手工解決,下面有操作。

requirements_all_ds 我只保留了3個package：pymssql, pyhive, mysqlclient：Successfully installed mysqlclient-1.3.14 pyhive-0.6.1 pymssql-2.1.4

如果全部安裝會卡住：

Getting requirements to build wheel ...\ 之后無反應，暫時沒有定位原因

編譯

npm install --legacy-peer-deps

##將路徑切換到redash根目錄，否則執(zhí)行編譯安裝，會報下面問題；--legacy-peer-deps保證本地package版本與遠程版本不一致時，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! enoent ENOENT: no such file or directory, open '/usr/include/package.json' npm ERR! enoent This is related to npm not being able to find a file. npm ERR! enoentnpm ERR!

查看yarn是否被安裝且鏡像要設置國內

yarn -v

配置

前端這邊不得不提一點，redash 項目前后端分離。中間依托了前端 node 的一個叫 dev-server 的服務器用于轉發(fā)前后端請求。所以當我們在訪問 redash 的時候其實請求會先打到 node 服務器那邊然后再由 node 的服務器進行轉發(fā)到后端 flask 服務器。

這里因為我只打算在入口的位置來配置 nginx 服務器，并不打算在 redash 服務器這邊再用 nginx 轉發(fā)一下。所以這里我需要配置 redash 的 node 服務器去監(jiān)聽 0.0.0.0 所有范圍的8080 端口。8080端口是默認的所以我修改了 node 里面的 webpack.config.js 配置指定讓 devServer 監(jiān)聽 0.0.0.0 地址。

服務器端部分其實有很多值得注意的地方。首先 readsh 給我們的默認配置是默認我們剛才將那些組件都安裝在了同一臺機器上面，否則你就必須面臨一個重新配置相關配置參數(shù)的局面。好在 redash 將配置文件的修改放在了還算清晰的地方。

如果你沒有在代碼里面添加 .env 文件，所有后端服務啟動的時候會默認去讀取環(huán)境變量中的配置。如果環(huán)境變量里面沒有配置相關的參數(shù)，那么將會直接使用所有參數(shù)的默認值加載。

redash 的配置寫在 -> redash/redash/settings/__init__.py 中，這里囊括了所有的配置。如果使用環(huán)境變量的配置要到這里來這里參考 key 的名稱。

redash目錄：/var/tools/redash

webpack.config.js

#localhost改成127.0.0.1，linux會把localhost解析成ipv6，導致前端請求在后臺代理轉發(fā)時，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，在后續(xù)啟動node運行npm run start時，會運行這段代碼

"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，不用動

_REDIS_URL = os.environ.get("REDASH_REDIS_URL", os.environ.get("REDIS_URL", "redis://localhost:6379/0") )

配置redash數(shù)據(jù)庫地址：指向postgres地址

SQLALCHEMY_DATABASE_URI = os.environ.get("REDASH_DATABASE_URL", os.environ.get("DATABASE_URL", "postgresql://用戶名:密碼@192.168.16.43/數(shù)據(jù)庫") )

配置加密key，key值隨機生成

python -c 'import secrets; print(secrets.token_hex())'結果輸出： #用于設置REDASH_COOKIE_SECRET (env_redash) [root@localhost redash]# python -c 'import secrets; print(secrets.token_hex())' 1d651e7057be0307a9ef8527c19ffec18f22de2ab5fdf2a71ff5ceda79abfec0 #用于設置REDASH_SECRET_KEY (env_redash) [root@localhost redash]# python -c 'import secrets; print(secrets.token_hex())' 3fb8928e0314191a9177097d6578e6276159e9b267a4dca108dc550a6f89654fSECRET_KEY = os.environ.get("REDASH_COOKIE_SECRET","1d651e7057be0307a9ef8527c19ffec18f22de2ab5fdf2a71ff5ceda79abfec0")

新建.env文件

在redash根目錄下建環(huán)境文件.env，REDASH_COOKIE_SECRET和REDASH_SECRET_KEY與__init__.py一致

NUNBUFFERED="0" REDASH_LOG_LEVEL="INFO" REDASH_REDIS_URL="redis://localhost:6379/0" POSTGRES_PASSWORD="Gao****2" REDASH_COOKIE_SECRET="1d651e7057be0307a9ef8527c19ffec18f22de2ab5fdf2a71ff5ceda79abfec0" REDASH_SECRET_KEY="3fb8928e0314191a9177097d6578e6276159e9b267a4dca108dc550a6f89654f" REDASH_DATABASE_URL="postgresql://postgres:Gao****2@192.168.85.131:5432/postgres" REDASH_BACKEND="http://127.0.0.1:5000"

檢查

bin/run ./manage.py check-settings

初始化數(shù)據(jù)庫

6.啟動

前端node server

npm run start 或 nohup npm run start </dev/null >out.log 2>&1 &

后端flask server

./manage.py runserver --debugger --reload 或 #加載.env 環(huán)境變量 bin/run ./manage.py runserver --debugger --reload

啟動worker

./manage.py rq worker

啟動schedule

./manage.py rq scheduler

解決：

此時！！！需要有一個github上的賬號（我用我的跟人帳號登錄）官網(wǎng)：https://github.com/

首先，在命令行創(chuàng)建公密鑰，一路回車即可

ssh-keygen -t rsa cat /root/.ssh/id_rsa.pub #公鑰，將以下內容加入 github 的 key

然后，登錄https://github.com/，界面選擇Settings --> SSH and GPG keys -->new SSH keys；

Title填入：自定義名稱和 Key填入：你虛擬機上的 /root/.ssh/id_rsa.pub 的公鑰內容；保存即可。

問題：

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：當前安裝的node版本是18，產生版本沖突，因為 node.js V17版本中最近發(fā)布的OpenSSL3.0, 而OpenSSL3.0對允許算法和密鑰大小增加了嚴格的限制

參考https://www.pudn.com/news/633d4b902aaf6043c9ecf2a2.html

解決1：不卸載當前版本，增加設置,我選的方法

yarn config set ignore-engines true#臨時設置： export NODE_OPTIONS=--openssl-legacy-provider #永久設置： vi /etc/profile export NODE_OPTIONS="--openssl-legacy-provider" source /etc/profile

解決2：重裝14.x或16.x，沒有實測過

root帳號運行：

curl -fsSL https://rpm.nodesource.com/setup_16.x | sudo bash -

curl -fsSL https://rpm.nodesource.com/setup_14.x | bash -

問題：運行 bin/run ./manage.py check-settings，

報錯誤：ModuleNotFoundError: No module named 'pystache'

ModuleNotFoundError: No module named 'passlib'

分析：在配置python虛擬環(huán)境時，安裝requirement.txt引用的包時，注釋了pystache，passlib

解決：安裝

pip install pystache==0.5.4

pip install passlib==1.7.1

問題：安裝pystache，error in pystache setup command: use_2to3 is invalid.

分析：

后面看這個項目的描述，原來是一個中文分詞的庫，一開始是用C++寫的并提供給Ruby用的，后面作者又寫了python的接口，不過支持的版本一直在python 2.5+，于是在python3的版本進行安裝的時候，會在setuptools里的setup函數(shù)里增加一個use_2to3=True的參數(shù)進行轉換。

但是setuptools>=58的版本是不支持這個參數(shù)了（黑人問號），于是需要把版本降低，小于58的最后一個版本是57.5.0，pip降一下就可以了

解決：

pip install setuptools==57.5.0 pip install pystache==0.5.4

問題：/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>.

解決：

pip install psycopg2-binary==2.8.3

問題：[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：這個問題困擾我整整兩天時間

原因是就是前端請求與后端服務監(jiān)聽的IP地址不一致，造成前端請求無法發(fā)送到爭取的IP地址和端口。

npm run start啟動之后，初始化的proxy target地址是localhost:5000

#webpack.config.js const redashBackend = process.env.REDASH_BACKEND || "http://localhost:5000"; 這里的localhost在執(zhí)行npm run start時，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/ ... ...目前發(fā)現(xiàn)，這個localhost只能通過2行的位置設置，設置環(huán)境變量.env中的REDASH_BACKEND，不起作用，原因待調查。

在webpack runserver 時日志如下：

bin/run ./manage.py runserver --debugger --reload

日志中 http://127.0.0.1:5000/ 為后端請求的地址,啟動后，創(chuàng)建兩個進程：一個服務進程，一個debugger進程

netstat -tlunp #查看接口占用 Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 853/postmaster tcp 0 0 127.0.0.1:5000 0.0.0.0:* LISTEN 7324/python tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 3089/redis-server * tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 845/sshd tcp6 0 0 :::5432 :::* LISTEN 853/postmaster tcp6 0 0 :::6379 :::* LISTEN 3089/redis-server * tcp6 0 0 :::22 :::* LISTEN 845/sshd udp 0 0 0.0.0.0:36241 0.0.0.0:* 5429/python udp 0 0 127.0.0.1:323 0.0.0.0:* 831/chronyd udp 0 0 0.0.0.0:42587 0.0.0.0:* 5388/python udp6 0 0 ::1:323 :::* 831/chronyd ps aux #查看具體執(zhí)行進程號對應的命令 root 7324 2.7 1.7 1169436 138972 pts/3 Sl 19:17 0:15 /var/py_virtual/env_redash/bin/python /var/tools/redash/manage.py runserver --debugger --reload

從信息可以看出，服務監(jiān)聽的地址127.0.0.1 ，端口5000；而前端請求的地址是localhost，端口5000，但是linux解析localhost成IPV6，而不是127.0.0.1。造成前后端無法對齊。

解決：

修改webpack.config.js

const redashBackend = process.env.REDASH_BACKEND || "http://127.0.0.1:5000";

.殺掉服務端進程包括8080端口、5000端口，然后重新運行npm run start，這時查看日志，地址已經改成127.0.0.1；

重新運行
