什么是uwsgi？
uWSGI是一个Web服务器，它实现了WSGI协议、uwsgi、http等协议。Nginx中HttpUwsgiModule的作用是与uWSGI服务器进行交换。WSGI是一种Web服务器网关接口。它是一个Web服务器（如nginx，uWSGI等服务器）与web应用（如用Flask框架写的程序）通信的一种规范。
- WSGI是一种通信协议。
- uwsgi是一种线路协议而不是通信协议，在此常用于在uWSGI服务器与其他网络服务器的数据通信。uwsgi协议是一个uWSGI服务器自有的协议，它用于定义传输信息的类型（type of information），每一个uwsgi packet前4byte为传输信息类型描述，它与WSGI相比是两样东西。
- uWSGI是实现了uwsgi和WSGI两种协议的Web服务器。
在开始之前
最小化安装CentOS 6
备份网卡文件
~$ mkdir /etc/sysconfig/network-scripts/backup ~$ cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/backup/ifcfg-eth0.backup
配置阿里云镜像源
~$ mkdir /etc/yum.repos.d/old ~$ mv /etc/yum.repos.d/CentOS-* /etc/yum.repos.d/old/ ~$ cd /etc/yum.repos.d/ ~$ curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo ~$ yum clean all && yum repolist all && yum update -y ~$ reboot
Python3.6.0
上传Python-3.6.0.tar.xz
~$ rz
安装依赖
yum install zlib* gcc openssl openssl-devel libffi-devel -y yum install pcre pcre-devel pcre-static -y
解压Python-3.6.0.tar.xz
~$ tar -xvf Python-3.6.0.tar.xz ~$ cd Python-3.6.0
修改部分源代码
~$ vim Modules/Setup.dist # 将该文件的204到209行部分代码取消注释，完成后如下所示： # Socket module helper for socket(2) _socket socketmodule.c # Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: SSL=/usr/local/ssl _ssl _ssl.c -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl -L$(SSL)/lib -lssl -lcrypto # The crypt module is now disabled by default because it breaks builds
编译安装
~$ ./configure ~$ make -j ~$ make install ~$ cd ~$ rm -rf Python-3.6.0
防火墙
# 恢复默认配置 iptables -F # 放通3306/8000/80端口 iptables -I INPUT -p tcp -m tcp --dport 3306 -j ACCEPT iptables -I INPUT -p tcp -m tcp --dport 8000 -j ACCEPT iptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPT # 保存规则 /etc/init.d/iptables save
SELinux
关闭SELinux
~$ vim /etc/selinux/config # 修改配置为如下所示： SELINUX=permissive ~$ reboot
数据库
二进制方式安装
# 查找相关旧文件并删除 find / -name mysql find / -name mariadb # 移除全部相关包 rpm -qa | grep mysql rpm -qa | grep mariadb # 添加用户 useradd mysql -s /sbin/nologin -M # 解压移动文件 tar -xvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz mv mysql-5.7.24-linux-glibc2.12-x86_64 /applications/ ln -s /applications/mysql-5.7.24-linux-glibc2.12-x86_64/ /applications/mysql # 创建配置文件 vim /etc/my.cnf # 创建相关目录 mkdir -p /data/mysql/data mkdir -p /data/mysql/log # 手动创建日志文件 touch /data/mysql/log/mysqld.log # 修改权限 chown -R mysql.mysql /applications/mysql chown -R mysql.mysql /data/mysql

# 同步数据 /applications/mysql/bin/mysql_install_db --basedir=/applications/mysql/ --datadir=/data/mysql/data/ --user=mysql
配置并启动
cp /applications/mysql/support-files/mysql.server /etc/init.d/mysqld chmod +x /etc/init.d/mysqld vim /etc/init.d/mysqld
# 修改以下两行 basedir=/applications/mysql datadir=/data/mysql/data
# 查看是否启动 netstat -tunlap | grep mysql # 添加服务并设置为开机自启动 chkconfig --add mysqld chkconfig mysqld on
初始化数据库
