前言

该系统和centos有一定的相似性，但是有一些小区别，所以在此记录项目所需依赖环境的搭建。

一 安装Python3.8

• 安装依赖

  yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel  -y
  

• 下载源码

  yum install wget -y
  wget https://www.python.org/ftp/python/3.8.13/Python-3.8.13.tgz
  

• 解压安装

  tar -zxvf Python-3.8.13.tgz
  cd Python-3.8.13
  # 安装位置为/usr/local/python3目录
  ./configure prefix=/usr/local/python3 --enable-optimizations
  sudo make && sudo make install
  

• 添加软链接

  ln -s /usr/local/python3/bin/python3.8 /usr/bin/python38 
  ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip3
  

• 使用Python3.8

  python38 app.py
  

二 安装 Mysql 5.7

• 安装

  yum -y install wget
  # 安装mysql官方 Yum Repository
  wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
  yum -y install ./mysql57-community-release-el7-10.noarch.rpm
  # 以2022年为例
  sudo rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
  yum -y install mysql-community-server
  # 启动
  systemctl start  mysqld.service
  systemctl status mysqld.service
  

• 修改密码

  # 获取临时密码
  grep "password" /var/log/mysqld.log
  # 使用临时密码登录
  mysql -uroot -p
  # 修改密码（ 包含大小写字母数字特殊字符不含单引号）
  mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Your_Password1';
  

• 开启远程访问

  # 指定远程登录的ip为192.168.0.1，使用%代替具体ip则表示登录ip任意
  mysql> grant all privileges on *.* to 'root'@'192.168.0.1' identified by 'Remote_Password1' with grant option;
  mysql> flush privileges;
  

• 开放3306端口

  firewall-cmd --zone=public --add-port=3306/tcp --permanent
  firewall-cmd --reload
  firewall-cmd --zone=public --list-ports
  

• 字符设置

  vim /etc/my.cnf
  # 在文首添加下面两行：
  [client]
  default-character-set=utf8
  # 在socket=/var/lib/mysql/mysql.sock下面添加两行：
  character-set-server=utf8
  collation-server=utf8_general_ci
  # 重启mysql
  systemctl restart mysqld.service
  

• windows访问

  mysql -h  ${host_ip}  -P  ${mysql_port}  -u root -p
  

三 安装Redis

• 安装

  yum install epel-release
  yum install redis
  # 启动redis
  sudo systemctl start redis
  # 查看redis运行状态
  service redis status
  

• 无法正常启动解决办法

  useradd redis -s /usr/sbin/nologin
  mkdir -p /var/log/redis
  chown -R redis:root /var/log/redis
  
  chown redis:root /etc/redis.conf
  
  mkdir -p /var/lib/redis
  chown -R redis:root /var/lib/redis
