安装新建coding目录， 编译安装软件
mkdir /coding
cd coding
1. 编译安装 python
- 安装依赖包
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel libffi-devel gcc make
- 下载包(华为镜像)
wget https://mirrors.huaweicloud.com/python/3.8.5/Python-3.8.5.tar.xz
- 解压
tar -zxvf Python-3.8.5.tar.xz
# 移动到自定义安装的目录
mv Python-3.8.5 /coding/py38
cd /coding/py38
- 编译安装
./configure --prefix=/coding/py38
make && make install
- 快捷方式
ln -s /coding/py38/bin/python3.8 /usr/bin/python3.8
ln -s /coding/py38/bin/python3.8 /usr/bin/python
ln -s /coding/py38/bin/pip3 /usr/bin/pip3
ln -s /coding/py38/bin/pip3 /usr/bin/pip
- 验证安装成功
python --version
pip --version
- yum 依赖的python2.7, 防止yum工作异常
find /usr/bin/ -type f -exec sed -i ':a;N;$!ba;s/\/usr\/bin\/python\([ \n]\)/\/usr\/bin\/python2.7\1/' {} \;
find /usr/libexec/ -type f -exec sed -i ':a;N;$!ba;s/\/usr\/bin\/python\([ \n]\)/\/usr\/bin\/python2.7\1/' {} \;
2. 编译安装nginx
- 安装依赖
yum -y install gcc gcc-c++ autoconf automake make pcre-devel openssl-devel
- 下载包( 华为源)

- 解压包
tar -zxvf nginx-1.21.6.tar.gz
mv nginx-1.21.6 /coding/nginx
cd /coding/nginx
- 编译安装
./configure --prefix=/coding/nginx
make && make install
- 常用命令
./nginx //启动
./nginx -s stop //停止
./nginx -s reload //重载配置
- 查询启动
ps -ef | grep nginx
- 创建软连接
ln -s /coding/nginx/sbin/nginx /usr/local/sbin
nginx //启动
nginx -s stop //停止
nginx -s reload
- nginx永久加入到系统环境变量

- 解压包
tar -zxvf redis-6.2.5.tar.gz
mv redis-6.2.5 /coding/redis
cd /coding/redis

make PREFIX=/coding/redis install
- 测试安装结果
make test
- 配置文件说明(redis.conf)

- 开启服务端:
./redis-server - 客户端访问:

chmod 775 /etc/init.d/redis - 设置自启:
chkconfig redis on
4. 安装mysql
参考：[centos8安装mysql8.0.22教程](https://blog.csdn.net/qq_39150374/article/details/112471108)
下载包(rpm)
wget https://dev.mysql.com/get/mysql80-community-release-el8-1.noarch.rpm
yum install mysql80-community-release-el8-1.noarch.rpm
检查数据源：
yum repolist enabled | grep "mysql.*-community.*"
错误： No match for argument: mysql-community-server
解决方法：yum module disable mysql
安装 MYSQL 命令
yum install mysql-community-server
错误：Error:GPG check FAILED
解决方法：yum 安装时添加 --nogpgcheck 参数
yum -y install xx --nogpgcheck
启动服务
genie -s # 在wsl子系统中实现systemd
systemctl start mysqld
显示MySQL临时密码
grep 'temporary password' /var/log/mysqld.log
输出： 2022-03-14T02:26:55.430178Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: 33HnSqi/jFK#
登录
mysql -u root -p //输入上面生成的密码
密码修改
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Root_21root';
错误 ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
解决办法:
一定要先修改默认密码为: Root_21root 满足它的策略,再进行下面的操作:
# 查看密码策略
mysql> SHOW VARIABLES LIKE 'validate_password%';
# 修改密码长度：
mysql> set global validate_password.length=1;
# 修改密码等级：
mysql> set global validate_password.policy=0;
# 设置成自己想要的密码:
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
开放远程访问
# 1、先创建权限记录
mysql> create user 'root'@'%' identified by 'root123';
# 2、授权
mysql> grant all privileges on *.* to 'root'@'%' with grant option;
更改加密方式
mysql> use mysql;
mysql> select user,plugin from user where user='root';
# 将用户的加密方式改为mysql_native_password。
mysql> alter user 'root'@'%' identified with mysql_native_password by 'Admin@123';
# 使权限配置项立即生效。
mysql> flush privileges;
解决错误：2059 - Authentication plugin ‘caching_sha2_password’ cannot be loaded:
