使用apt-fast 提升下载速度的软件，安装软件时，通过增加线程使下载软件速度加快。
add-apt-repository ppa:apt-fast/stable
apt-get install apt-fast
添加apt-fast的安装源 然后安装。
在出现的GUI画面依此选择替换apt-get， 最大线程16
CAVEATS:
- If you are using php-gearman, you need to add ppa:ondrej/pkg-gearman
- If you are using apache2, you are advised to add ppa:ondrej/apache2
- If you are using nginx, you are advised to add ppa:ondrej/nginx-mainline
or ppa:ondrej/nginx
add-apt-repository ppa:ondrej/apache2
add-apt-repository ppa:ondrej/nginx
add-apt-repository ppa:ondrej/php

数据库
MariaDB
由于MariaDB版本较多，建议在官方页面上生成配置文件内容。
https://mariadb.org/download/?spm=a2c6h.13651104.0.0.14ee5d599zLsUu&t=repo-config&d=22.04+%22jammy%22&v=10.9&r_m=aliyun
sudo apt-get install apt-transport-https curl
sudo curl -o /etc/apt/trusted.gpg.d/mariadb_release_signing_key.asc ‘https://mariadb.org/mariadb_release_signing_key.asc’
sudo sh -c “echo ‘deb https://mirrors.aliyun.com/mariadb/repo/10.9/ubuntu jammy main’ >>/etc/apt/sources.list”
sudo apt-get update
sudo apt-get install mariadb-server
MariaDB数据库初始化
mysql_secure_installation
可以通过Navicat工具里，ssh隧道方式进行连接
PostgreSQL数据库
Installing PostgreSQL
sudo apt install postgresql postgresql-contrib
Using PostgreSQL Roles and Databases
sudo -i -u postgres
psql
或者
sudo -u postgres psql
更改任何用户（包括 postgres）的密码：
ALTER USER postgres WITH PASSWORD ‘111111’;
添加超级用户和权限：
CREATE USER vipdb WITH PASSWORD ‘111111’;
ALTER USER vipdb WITH SUPERUSER;
查看数据库名称
SELECT * FROM pg_database ORDER BY datname;
centos7默认占用端口，查找进程、关闭禁止它开机启动
netstat -tan #查看端口
又查了一下PID
netstat -tanp #带PID名
端口对应程序为master,
具体程序
find / -name master #查了一下位置
/usr/libexec/postfix/master
找到程序名是postfix
systemctl stop postfix #停止服务
systemctl disable postfix #禁止开机启动
