部署前需要關閉防火墻：
`iptables -F`
### 安裝python3
環境centos7.2
下載、解壓（編譯安裝，把下載好的python3安裝包解壓）：
Linux下默認系統自帶python2.7的版本，這個版本被系統很多程序所依賴，所以不建議刪除，如果使用最新的Python3那么我們知道編譯安裝源碼包和系統默認包之間是沒有任何影響的，所以可以安裝python3和python2共存
首先去python官網下載python3的源碼包，網址：https://www.python.org/
進去之后點擊導航欄的Downloads，也可以鼠標放到Downloads上彈出菜單選擇Source code，就是源碼包的意思，這里選擇最新版本36.2，當然下面也有很多其他歷史版本，點進去之后頁面下方可以看到下載鏈接，包括源碼包、Mac OSX安裝包、Windows的安裝包
tar -xvf Python-3.6.2.tgz
* * * * *
進入目錄：
~~~
cd Python-3.6.2/
~~~
添加配置：
~~~
./configure --with-ssl --prefix=/usr/python
~~~
這里配置自己的安裝目錄，接下來編譯源碼、安裝：
~~~
make && make install
~~~
如果出現錯誤提示缺少zlib...啥的則需要安裝zlib相關依賴包
~~~
yum -y install zlib*
~~~
注：如果安裝后出現```Ignoring ensurepip failure: pip 9.0.1 requires SSL/TLS```
則 ```yum install -y openssl-devel```
2、進入 Python安裝包,修改Module路徑的setup文件：
~~~
vim Modules/Setup
~~~
找到下面一行代碼，去掉注釋：
~~~
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
去掉注釋
zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
~~~
系統中原來的python在/usr/bin/python，通過ls -l可以看到，python是一個軟鏈接，鏈接到本目錄下的python2.7
我們可以把這個刪除，也可以新建一個python3的軟鏈接，只不過執行時python要改成python3，或者python腳本頭部聲明要改為#!/usr/bin/python3
```
ln -s /usr/python/bin/python3 /usr/bin/python3
```
#### 安裝pip
~~~
wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
python3 get-pip.py
~~~
如果pip安裝模塊時提示
~~~
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
~~~
則需要安裝openssl
~~~
yum install -y openssl-devel
~~~
然后重新編譯安裝即可
#### 安裝virtualenv
~~~
pip install virtualenv
mkdir myproject
cd myproject
virtualenv --no-site-packages venv (指定python版本：virtualenv -p /usr/bin/python3 venv)
linux:source venv/bin/activate windows:venv\Scripts\activate
deactivate 退出
~~~
注：如果出現 ```bash: pip: command not found```
首先查找pip安裝目錄 ```find / -name pip```
然后建立軟鏈 ```ln -s /usr/python/bin/pip /usr/bin/pip ```
#### 安裝uwsgi
~~~
pip install uwsgi
~~~
配置uwsgi
在網站根目錄下創建config.ini文件，寫入以下內容
~~~
[uwsgi]
# uwsgi 啟動時所使用的地址與端口
socket = 127.0.0.1:8001
# 指向網站目錄
chdir = /home/project/flask/
# python 啟動程序文件
wsgi-file = manage.py
# python 程序內用以啟動的 application 變量名
callable = app
# 處理器數
processes = 4
# 線程數
threads = 2
#狀態檢測地址
stats = 127.0.0.1:9191
~~~
#### 安裝nginx
~~~
yum -y install nginx
~~~
配置nginx
~~~
vim /etc/nginx/conf.d/default.conf
server{
listen 80;
server_name www.chenyy.xin;
root /home/project/flask;
location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8001; # 指向uwsgi 所應用的內部地址,所有請求將轉發給uwsgi 處理
uwsgi_param UWSGI_PYHOME /home/project/flask/flask_env361; # 指向虛擬環境目錄
uwsgi_param UWSGI_CHDIR /home/project/flask; # 指向網站根目錄
uwsgi_param UWSGI_SCRIPT manage:app; # 指定啟動程序
}
}
開啟
/bin/systemctl start nginx.service
重啟
/bin/systemctl restart nginx.service
~~~
#### 安裝supervisor
~~~
yum install python-setuptools
pip install supervisor
~~~
測試是否安裝成功
~~~
echo_supervisord_conf
~~~
創建配置文件
~~~
mkdir -m 755 -p /etc/supervisor/
cd /etc
echo_supervisord_conf > /etc/supervisor/supervisord.conf
cd supervisor
~~~
創建項目配置文件目錄
~~~
mkdir -m 755 conf.d
cd /etc/supervisor/conf.d
vim flask.conf
[program:flask]
command =/home/project/flask/flask_env361/bin/uwsgi /home/project/flask/config.ini
directory =/home/project/flask
user =root
autostart=true
autorestart=true
startsecs=5
priority=1
stopasgroup=true
killasgroup=true
stderr_logfile=/home/project/log/error.log#要確保該目錄存在
~~~
在主配文檔中引入flask.conf
~~~
vim supervisord.conf
~~~
找到include
~~~
;[include]
;files = relative/directory/*.ini
//改為
[include]
files = ./conf.d/*.conf
~~~
啟動supervisor
~~~
supervisord -c supervisord.conf
~~~
如果出現以下錯誤
~~~
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /root/.pyenv/versions/2.7.6/bin/supervisord -h
~~~
找到 supervisor.sock
~~~
unlink supervisor.sock
~~~
重新啟動supervisor
用supervisorctl查看已經被監控的program
~~~
(flask_env361) [root@iZ2zefw4wlcm0he1pjkawoZ supervisor]# supervisorctl
flask RUNNING pid 1764, uptime 0:59:45
~~~
如果supervisorctl沒效果，換成
~~~
supervisorctl -c /etc/supervisor/supervisord.conf
~~~
重啟監控服務
~~~
supervisorctl reload
~~~
異常解決
~~~
[root@iZ2zefw4wlcm0he1pjkawoZ supervisor]# supervisorctl
unix:///tmp/supervisor.sock no such file
supervisor> reload
Really restart the remote supervisord process y/N? y

~~~
#### 安裝mysql
1.下載MySQL源
~~~
wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
~~~
2.安裝MySQL源
~~~
sudo rpm -ivh mysql57-community-release-el7-7.noarch.rpm
~~~
3.安裝mysql-community-server
~~~
sudo yum install mysql-community-server -y
~~~
4.重啟mysql
~~~
systemctl restart mysqld
注：自動啟動服務用 systemctl enable mysqld
~~~
5.查看臨時密碼
~~~
grep 'A temporary password' /var/log/mysqld.log
~~~
6.數據庫修改密碼
~~~
set global validate_password_policy=0;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxxxxx';
~~~
yum -y install mysql-devel
