https://www.python.org/downloads/release/python-370/

2.安裝web server需要的庫(kù)和服務(wù)

1.安裝mysql网沾，查看mysql的安裝教程

安裝完測(cè)試正常后初茶，使用以下命令部署web的后臺(tái)數(shù)據(jù)庫(kù)框架
mysql -u root -p < schema.sql

2.pip3 install jinja2 aiomysql aiohttp

3.安裝pyCharm64

win上面開(kāi)發(fā)一定要有集成開(kāi)發(fā)環(huán)境，使用pyCharm很方便所踊。

Centos下安裝

1.安裝python

編譯時(shí)要提前裝好gcc編譯器和zlib zlib-devel

下載Python安裝包

cd /usr/local/src
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

2污筷、解壓

tar -zxvf Python-3.7.0.tgz

3工闺、編譯安裝包

cd Python-3.7.0
./configure --prefix=/usr/local/python
make && make install

4乍赫、添加環(huán)境變量

#echo PATH='/usr/local/python/bin/:$PATH' >> /etc/profile
<br>#source /etc/profile

有時(shí)候會(huì)出現(xiàn)如下錯(cuò)誤

ModuleNotFoundError: No module named '_ctypes'

安裝如下即可：

yum install libffi-devel -y

5.檢查是否成功，執(zhí)行下面代碼

python3.7
Python 3.7.0 (default, Nov 27 2018, 10:35:54)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

2.修改默認(rèn)python版本（這一步可能不需要陆蟆，因?yàn)闀?huì)導(dǎo)致supervisorctl啟動(dòng)不了雷厂，supervisorctl只能要python2上面跑）

1.查看默認(rèn)python版本是2.7.5

python
Python 2.7.5 (default, Jul 13 2018, 13:06:57)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

2.修改系統(tǒng)默認(rèn)的Python路徑，因?yàn)樵诮K端中輸入Python命令時(shí)默認(rèn)是指向Python2.7.5

mv /usr/bin/python /usr/bin/python-2.7.5
```　

3.建立新的軟連接叠殷，指向Python-3.7.0  

ln -s /usr/local/python/bin/python3.7 /usr/bin/python
　```

4.打開(kāi)一個(gè)新的終端改鲫，通過(guò)python命令進(jìn)入python環(huán)境，可以看到已經(jīng)指向了我們新安裝的python3.7.0：

python
Python 3.7.0 (default, Nov 27 2018, 10:35:54)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print("test")
test
>>> exit()

5.改完默認(rèn)python后發(fā)現(xiàn)使用yum安裝時(shí)出錯(cuò)

 yum install openssh-server
  File "/usr/bin/yum", line 30
    except KeyboardInterrupt, e:
                            ^
SyntaxError: invalid syntax

6.因?yàn)閥um是依賴python的林束，所以這里我們修改了默認(rèn)的python,就要要修改yum像棘，讓其運(yùn)行指向舊的版本：

vi /usr/bin/yum   

將第一行中的“#!/usr/bin/python”   
修改為“#!/usr/bin/python-2.7.5”
保存即可

7.如果出現(xiàn)別的錯(cuò)誤的時(shí)候有可以需要修改一下兩個(gè)文件

yum install tree

Exiting on user cancel

1. vim /usr/libexec/urlgrabber-ext-down

將/usr/bin/python改為/usr/bin/python-2.7.5。

2. vim /usr/bin/yum-config-manager

解決辦法同上： #!/usr/bin/python換成 #!/usr/bin/python-2.7.5 

3.安裝web server需要的庫(kù)和服務(wù)

1.安裝mysql壶冒，查看mysql的安裝教程

安裝完測(cè)試正常后缕题，使用以下命令部署web的后臺(tái)數(shù)據(jù)庫(kù)框架
mysql -u root -p < schema.sql

2.pip3 install jinja2 aiomysql aiohttp

3.yum install openssh-server nginx supervisor dos2unix

這邊用到下面兩個(gè)工具

• 1.Supervisor：監(jiān)控服務(wù)進(jìn)程的工具；

該工具的主要目的就是使用Supervisor來(lái)啟動(dòng)我們的app.py進(jìn)程胖腾，這樣app.py進(jìn)程出現(xiàn)問(wèn)題時(shí)就會(huì)被保存日志重啟等烟零。

使用echo_supervisord_conf產(chǎn)生默認(rèn)配置文件，保存在supervisord.conf里面

echo_supervisord_conf > /etc/supervisord.conf

修改/etc/supervisord.conf的最后兩行

[include]
files = /etc/supervisord.d/*.conf

在/etc/supervisord.d/里面添加配置文件awesome.conf

[program:awesome]
command     = /srv/awesome/www/app.py
directory   = /srv/awesome/www
user        = root
startsecs   = 3
redirect_stderr         = true
stdout_logfile_maxbytes = 50MB
stdout_logfile_backups  = 10
stdout_logfile          = /srv/awesome/log/app.log

查看要運(yùn)行的www屬于誰(shuí)的權(quán)限咸作，就將上面awesome.conf里面的user配置成誰(shuí)

[root@centos awesome]# ls -l
total 24
drwxr-xr-x 2 root root 4096 Nov 27 17:23 log
lrwxrwxrwx 1 root root   21 Nov 27 16:56 www -> www-18-11-27_16.56.28

參考：https://www.cnblogs.com/wswang/p/5795766.html

supervisorctl stop program_name  # 停止某一個(gè)進(jìn)程锨阿，program_name 為 [program:x] 里的 x

supervisorctl start program_name  # 啟動(dòng)某個(gè)進(jìn)程

supervisorctl restart program_name  # 重啟某個(gè)進(jìn)程

supervisorctl stop groupworker:  # 結(jié)束所有屬于名為 groupworker 這個(gè)分組的進(jìn)程 (start，restart 同理)

supervisorctl stop groupworker:name1  # 結(jié)束 groupworker:name1 這個(gè)進(jìn)程 (start记罚，restart 同理)

supervisorctl stop all  # 停止全部進(jìn)程墅诡，注：start、restartUnlinking stale socket /tmp/supervisor.sock
桐智、stop 都不會(huì)載入最新的配置文件

supervisorctl reload  # 載入最新的配置文件书斜，停止原有進(jìn)程并按新的配置啟動(dòng)、管理所有進(jìn)程

supervisorctl update  # 根據(jù)最新的配置文件酵使，啟動(dòng)新配置或有改動(dòng)的進(jìn)程荐吉，配置沒(méi)有改動(dòng)的進(jìn)程不會(huì)受影響而重啟

[root@centos awesome]# supervisorctl stop awesome
awesome: stopped
[root@centos awesome]# supervisorctl start awesome
awesome: started
[root@centos awesome]# supervisorctl status
awesome                          RUNNING   pid 30182, uptime 0:00:13

測(cè)試下supervisord進(jìn)程是否生效，找到app.py的進(jìn)程kill掉口渔，可以發(fā)現(xiàn)出現(xiàn)了一個(gè)新id的app.py進(jìn)程

[root@centos awesome]# ps -aux | grep python

• 2.Nginx：高性能Web服務(wù)器+負(fù)責(zé)反向代理样屠；

利用Python自帶的asyncio，我們已經(jīng)編寫了一個(gè)異步高性能服務(wù)器缺脉。但是痪欲，我們還需要一個(gè)高性能的Web服務(wù)器，這里選擇Nginx攻礼，它可以處理靜態(tài)資源业踢，同時(shí)作為反向代理把動(dòng)態(tài)請(qǐng)求交給Python代碼處理

動(dòng)靜結(jié)合，我們的python服務(wù)器屬于動(dòng)態(tài)的礁扮，會(huì)修改知举；Nginx屬于靜態(tài)的瞬沦，為代理作用，更加安全雇锡，比如python服務(wù)器出現(xiàn)問(wèn)題是逛钻，不會(huì)因?yàn)槭韬龆裠ebug信息直接輸出給客戶端，這時(shí)候就有Nginx服務(wù)器直接返回502錯(cuò)誤給客戶端锰提。

在阿里云服務(wù)器上由于沒(méi)有界面也不知道nginx是否正常啟動(dòng)曙痘，這時(shí)候可以使用curl去過(guò)去網(wǎng)頁(yè)內(nèi)容，然后再?gòu)?fù)制出來(lái)到win上面看html頁(yè)面是否顯示正常立肘。

如果在本機(jī)可以正常訪問(wèn)边坤，外網(wǎng)不能訪問(wèn)的時(shí)候，需要看下阿里云上面的安全組配置谅年，是否有開(kāi)放80端口茧痒，443端口。

如果還是不行可能需要配置防火墻規(guī)則踢故。

Ubuntu下安裝

1.安裝python

1文黎、apt-get upgrade

2惹苗、apt-get update

直接安裝python3.5吧殿较，發(fā)現(xiàn)3.6下安裝distribute有問(wèn)題

3、apt-get install python3.6

4桩蓉、apt-get install python3.6-dev

ubuntu默認(rèn)已經(jīng)安裝了python3.4

root@ubuntu:/usr/bin# python3 -V
Python 3.4.3

所以我們需要把默認(rèn)的改成python3.6

設(shè)置python的默認(rèn)版本：

root@ubuntu:/usr/bin# update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
update-alternatives: using /usr/bin/python2.7 to provide /usr/bin/python (python) in auto mode
root@ubuntu:/usr/bin# update-alternatives --list python
/usr/bin/python2.7
root@ubuntu:/usr/bin# python -V
Python 2.7.6

設(shè)置python3的默認(rèn)版

root@ubuntu:/usr/bin# update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1
update-alternatives: using /usr/bin/python3.6 to provide /usr/bin/python3 (python3) in auto mode
root@ubuntu:/usr/bin# update-alternatives --list python3
/usr/bin/python3.6
root@ubuntu:/usr/bin# python3 -V
Python 3.6.2

5淋纲、設(shè)置pip:

• apt-get install python3-pip　　　　# Python3
• apt-get install python-pip　　　　 # Python2

6、查看pip3 -V

root@ubuntu:/usr/bin# pip3
Traceback (most recent call last):
  File "/usr/bin/pip3", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources.py", line 1479, in <module>
    register_loader_type(importlib_bootstrap.SourceFileLoader, DefaultProvider)
AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'

AttributeError：module 'importlib._bootstrap' has no attribute 'SourceFileLoader'院究。

最后發(fā)現(xiàn)：distribute只能安裝在python 3.5.x版本洽瞬。

7、安裝apt-get install python3业汰、apt-get install python3.5-dev切換到3.5

root@ubuntu:/usr/bin# update-alternatives --config python3
There are 2 choices for the alternative python3 (providing /usr/bin/python3).

  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /usr/bin/python3.6   1         auto mode
  1            /usr/bin/python3.5   1         manual mode
* 2            /usr/bin/python3.6   1         manual mode

Press enter to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/python3.5 to provide /usr/bin/python3 (python3) in manual mode
root@ubuntu:/usr/bin# pip3 -V
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.5)

8伙窃、更新pip3

pip3 install --upgrade setuptools

2.安裝web server需要的庫(kù)和服務(wù)

1.安裝mysql，查看mysql的安裝教程

安裝完測(cè)試正常后样漆，使用以下命令部署web的后臺(tái)數(shù)據(jù)庫(kù)框架
mysql -u root -p < schema.sql

2.pip3 install jinja2 aiomysql aiohttp

pip3 install idna_ssl cryptography

3.apt-get install libssl-dev openssh-server nginx supervisor dos2unix

4.配置Supervisor：監(jiān)控服務(wù)進(jìn)程的工具

編寫一個(gè)Supervisor的配置文件awesome.conf为障，存放到/etc/supervisor/conf.d/目錄下：

[program:awesome]

command     = /srv/awesome/www/app.py
directory   = /srv/awesome/www
user        = root
startsecs   = 3

redirect_stderr         = true
stdout_logfile_maxbytes = 50MB
stdout_logfile_backups  = 10
stdout_logfile          = /srv/awesome/log/app.log

在srv下面創(chuàng)建awesome文件夾。

使用fabfile_win.py將項(xiàng)目同步到ubuntu,記得修改ip和用戶名放祟。

env.user = 'linye'
env.sudo_user = 'root'
# env.hosts = ['123.123.123.123']
env.host_string = '192.168.61.128' # 改成你的服務(wù)器ip

創(chuàng)建/srv/awesome/log/文件夾

service supervisor start

出現(xiàn)unix:///var/run/supervisor.sock no such file是就自己創(chuàng)建一個(gè)鳍怨，并附權(quán)限

touch /var/run/supervisor.sock
chmod 777 /var/run/supervisor.sock

5.Nginx：高性能Web服務(wù)器+負(fù)責(zé)反向代理；

/etc/nginx/sites-available/default里面的內(nèi)容改成如下：

server {
    listen      80; # 監(jiān)聽(tīng)80端口

    root       /srv/awesome/www;
    access_log /srv/awesome/log/access_log;
    error_log  /srv/awesome/log/error_log;

    # server_name awesome.liaoxuefeng.com; # 配置域名

    # 處理靜態(tài)文件/favicon.ico:
    location /favicon.ico {
        root /srv/awesome/www;
    }

    # 處理靜態(tài)資源:
    location ~ ^\/static\/.*$ {
        root /srv/awesome/www;
    }

    # 動(dòng)態(tài)請(qǐng)求轉(zhuǎn)發(fā)到9000端口:
    location / {
        proxy_pass       http://127.0.0.1:9000;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

/etc/init.d/nginx reload
