CentOS7部署nginx+uwsgi+django项目

- 安装python3

CentOS7系统自带的Python版本是Python2.7，如需使用Python3.6，需要自行安装Python3.6。

CentOS7安装Python3.6有两种方式：

• 使用Yum源安装Python3.6
• 使用Python3.6源文件安装

推荐使用CentOS7 Yum源安装Python3.6。

CentOS7使用Yum源安装Python3.6(已失效)

IUS软件源中包含了Python3.6，可以使用IUS软件源安装Python3.6，查看如何安装使用IUS软件源

1）安装IUS软件源

#安装EPEL依赖
yum install epel-release -y

#安装IUS软件源
yum install https://centos7.iuscommunity.org/ius-release.rpm -y

2）安装Python3.6

yum install python36u -y

安装Python3完成后的shell命令为python3.6，为了使用方便，创建一个到python3的符号链接

ln -s /bin/python3.6 /bin/python3

3）安装pip3

安装完成python36u并没有安装pip，安装pip

yum install python36u-pip -y

安装pip完成后的shell命令为pip3.6，为了使用方便，创建一个到pip3的符号链接

ln -s /bin/pip3.6 /bin/pip3

CentOS7使用Yum源安装Python3.6

1）安装IUS软件源

#安装EPEL依赖
yum install epel-release -y

#安装IUS软件源
yum install https://mirrors.tuna.tsinghua.edu.cn/ius/ius-release-el7.rpm -y

2）安装Python3.6

yum search python36
# 找到需要安装的python包
yum install xxxx -y


## CentOS7使用源文件安装Python3.6

1）在安装Python3.6之前，先安装Python3.6需要的依赖：

sudo yum -y groupinstall development
sudo yum -y install zlib-devel

2）运行如下命令安装Python3.6

wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.xz
tar xJf Python-3.6.0.tar.xz
cd Python-3.6.0
sudo ./configure
sudo make
sudo make install

安装完成后，Python安装在了`/usr/local`文件夹中，可运行文件`/usr/local/bin`，库文件`/usr/local/lib`

###- nginx配置文件
```vim /etc/nginx/conf.d/py.conf ```

server {
listen 80;
server_name 47.102.129.254;
client_max_body_size 100M;

location /static {
alias /root/code/FULL_BBS/static;
}

location /media {
alias /root/code/FULL_BBS/media/;
}

location / {
index index.html;
include uwsgi_params;
uwsgi_pass 127.0.0.1:9090;
uwsgi_param UWSGI_SCRIPT FULL_BBS.wsgi;
uwsgi_param UWSGI_CHDIR /root/code/FULL_BBS;
}
}

###- uwsgi配置文件
```pip3 install uwsgi安装失败问题的解决```

1. python --version 命令查看python版本
2. yum search python3
3. yum install python36u-devel.x86_64 -y
   4.或者yum install gcc -y

```vim 项目最外层目录/uwsgi.ini```

[uwsgi]
socket = 127.0.0.1:9090
master = true
workers = 2
reload-mercy = 10
vacuum = true
max-requests = 1000
limit-as = 512
buffer-size = 30000
