创建用户并赋予sudo权限
sudo vim /etc/sudoers
#赋值一行root ALL=(ALL) ALL并将root改成自己的名字就行安装Python
设置优先级
调整python3的优先级，
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5.1 sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6.2更改默认值，python默认为python2，现在修改为python3
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100 sudo update-alternatives --install /usr/bin/python python /usr/bin/pyhton3 150安装pip3
apt-get install python3-pip #为python3添加包 pip3 install packagename
mysql的安装，对外开放
卸载残余的mysql
#查看是否有残余的mysql
rpm -qa | grep mysql
#删除系统内mysql的信息
rpm -e mysql // 普通删除模式
rpm -e --nodeps mysql // 强力删除模式，如果使用上面命令删除时，提示有依赖的其它文件，则用该命令可以对其进行强力删除安装mysql
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum update
yum install mysql-server
chown mysql:mysql -R /var/lib/mysql
mysqld --initialize
systemctl start mysqld查询初始密码
grep 'temporary password' /var/log/mysqld.log修改密码
#mysql 修改密码
set password for root@localhost = password('nuocheng'); 或者
use mysql;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'nuocheng';设置root可以远程登录
在本机先使用root用户登录mysql：
mysql -u root -p "youpassword"
进行授权操作：
GRANT ALL PRIVILEGES ON *.* TO root@"39.99.225.54" IDENTIFIED BY "nuocheng" WITH GRANT OPTION;
重载授权表：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'nuocheng'
FLUSH PRIVILEGES;
退出mysql数据库：Anaconda的配置
export PATH=/root/anaconda3/bin:$PATHnginx的安装
#安装依赖包
yum install -y pcre pcre-devel openssl openssl-devel gcc gcc gcc-c++ ncurses-devel perl 首先安装PCRE
PCRE 作用是让 Nginx 支持 Rewrite 功能。
1、下载 PCRE 安装包，下载地址： http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
tar -zxvf pcre-8.35.tar.gz
cd pcre-8.35./configure
make && make install下载并安装nginx
wget http://nginx.org/download/nginx-1.6.2.tar.gz
tar zxvf nginx-1.6.2.tar.gz
cd nginx-1.6.2
./configure
make
make installuwsgi的安装
yum install -y gcc* pcre-devel openssl-devel --skip-broken
yum install -y python-devel
pip install uwsgi查询版本yum search python | grep -i devel
安装过程中如果出现缺少目录lib*可以使用
whereis lib** 然后进行下面的操作
uwsgi出现的软连接问题
