Linux 设置虚拟内存

:::tip

该操作流程采用 Ubuntu 20.04 操作系统，Debain 如无 sudo 命令则可以去掉即可

:::

查看虚拟内存

free

创建虚拟内存配置文件

新建文件夹

mkdir /swap

进入文件夹

cd /swap

创建虚拟文件，bs 为块的大小，count 创建多少个块

sudo dd if=/dev/zero of=swapfile bs=1M count=2048

修改权限

sudo chmod 0600 swapfile

把生成的文件转换成 Swap 文件

sudo mkswap swapfile

激活文件

sudo swapon swapfile

再次查看虚拟内存（执行命令可以看到新增了2G）

free

如果需要释放的话（执行命令后，删除创建的swap目录即可）

sudo swapoff swapfile

如果需要开机自动使用该虚拟内存的话，则需要加入到启动脚本

打开 /etc/fstab 文件

vi /etc/fstab

此时开的虚拟内存会在开机后消失,如果永久保持下去,在 /etc/fstab 文件尾添加一下信息:

/swap/swapfile swap swap defaults 0 0

npm 设置代理

npm config set proxy=http://127.0.0.1:10809
npm config set https-proxy=http://127.0.0.1:10809

SSL 证书申请（acme.sh）

SSL 证书申请

方式1：acme.sh

该方式基于 Ubuntu 20.04、Nginx 1.22 测试通过，更多用法可前往Github查看

1.安装acme.sh

先安装socat

apt install socat -y

邮箱替换成自己的

curl https://get.acme.sh | sh -s [email protected]

2.source

source ~/.bashrc

3.生成证书（这里采用DNS方式，HTTP方式请前往Github查看）

设置dns运营商的识别 ID 和 Secret (已设置的无需重复设置)，acme也支持多家dsn运营商，我这里采用的是阿里云

export Ali_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
export Ali_Secret="jlsdflanljkljlfdsaklkjflsa"

切换CA机构（默认ZeroSSL，ZeroSSL老是容易超时，中意ZeroSSL可以忽略）

acme.sh --set-default-ca --server letsencrypt

申请证书

acme.sh --issue --dns dns_ali -d example.com

4.安装证书（不要直接引用acme生成的路径，也不要使用复制的方式，手动复制会使自动更新失效）

这里的路径就是实际就是你想存放证书的路径，对应文件夹要提前创建（例如我习惯放置的路径为/root/cert/域名.后缀）

acme.sh --install-cert -d example.com \
--key-file       /root/cert/example.com.key  \
--fullchain-file /root/cert/example.com.cer

5.配置 Nginx

#以下属性中，以ssl开头的属性表示与证书配置有关。
server {
    listen 443 ssl;
    #配置HTTPS的默认访问端口为443。
    #如果未在此处配置HTTPS的默认访问端口，可能会造成Nginx无法启动。
    #如果您使用Nginx 1.15.0及以上版本，请使用listen 443 ssl代替listen 443和ssl on。
    server_name example.com;
    ssl_certificate /root/cert/example.com.cer;
    ssl_certificate_key /root/cert/example.com.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    #表示使用的加密套件的类型。
    ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3; #表示使用的TLS协议的类型，您需要自行评估是否配置TLSv1.1协议。
    ssl_prefer_server_ciphers on;
    add_header Strict-Transport-Security "max-age=31536000";
    location / {
        root html;  #Web网站程序存放目录。
        index index.html index.htm;
    }
}

server {
    listen 80;
    server_name example.com;
    add_header Strict-Transport-Security "max-age=31536000";
    rewrite ^(.*)$ https://$host$1;
}

6.完成

可以尝试检测或访问

https://myssl.com/ssl.html

更新：acme.sh会自动更新证书

常用的 docker-compose 配置文件

Postgresql

version: "3"

services:
  postgres:
    container_name: postgres
    image: postgres:15.6
    restart: always
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: 123456
      POSTGRES_DB: db
    ports:
      - "5432:5432"
    volumes:
      - ./data:/var/lib/postgresql/data

Postgresql 安装和访问

1.安装

:::tip

该安装环境采用 Debain 11，其他系统可参照官方文档

:::

创建文件存储库配置

sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

导入存储库签名密钥

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | apt-key add -

更新软件包列表

apt update

安装默认默认版本

apt install postgresql -y

安装特定版本（-后面为你想要的版本）

apt install postgresql-14 -y

2.修改密码

Postgresql 会默认创建一个 postgres 用户，切换用户

su postgres

然后就可以使用psql命令交互工具使用

psql

修改密码

alter user postgres with password '123456';

3.设置外网访问

如果不清楚配置文件路径存放的可以查看进程

ps -ef|grep postgresql

结果如下

postgres    8451       1  0 14:44 ?        00:00:00 /usr/lib/postgresql/14/bin/postgres -D /var/lib/postgresql/14/main -c 		config_file=/etc/postgresql/14/main/postgresql.conf
root        9043    8507  0 15:38 pts/1    00:00:00 grep postgresql

修改配置文件postgresql.conf，将listen_addresses的值改为*，记得去掉前面的#注释，同时该文件有pg_hba.conf的文件路径，这个文件也要修改

vi /etc/postgresql/14/main/postgresql.conf

文件部分内容如下

#------------------------------------------------------------------------------
# FILE LOCATIONS
#------------------------------------------------------------------------------

# The default values of these variables are driven from the -D command-line
# option or PGDATA environment variable, represented here as ConfigDir.

data_directory = '/var/lib/postgresql/14/main'		# use data in another directory
					# (change requires restart)
hba_file = '/etc/postgresql/14/main/pg_hba.conf'	# host-based authentication file
					# (change requires restart)
ident_file = '/etc/postgresql/14/main/pg_ident.conf'	# ident configuration file
					# (change requires restart)

# If external_pid_file is not explicitly set, no extra PID file is written.
external_pid_file = '/var/run/postgresql/14-main.pid'			# write an extra PID file
					# (change requires restart)


#------------------------------------------------------------------------------
# CONNECTIONS AND AUTHENTICATION
#------------------------------------------------------------------------------

# - Connection Settings -

listen_addresses = '*'  		# what IP address(es) to listen on;
					# comma-separated list of addresses;
					# defaults to 'localhost'; use '*' for all
					# (change requires restart)
port = 5432				# (change requires restart)
max_connections = 100			# (change requires restart)
#superuser_reserved_connections = 3	# (change requires restart)
unix_socket_directories = '/var/run/postgresql'	# comma-separated list of directories

修改配置文件pg_hba.conf，直接在文件末尾添加以下配置项，可根据需要自己调整对应值

host all all 0.0.0.0/0 md5

重启 Postgresql

systemctl restart postgresql.service

4. 常用命令

修改用户密码

alter user postgres with password '123456';

创建普通用户

create user test encrypted password '123456';

创建超级用户

create user test superuser encrypted password '123456';

将超级用户改为普通用户

alter user test nosuperuser;

普通用户改为超级用户

alter user test superuser;

设置不允许/允许其登录

alter user test nologin;
alter user test login;

Git 设置代理

本地代理协议根据对应代理工具使用协议，例如：Windows的V2rayN默认采用socks，端口10808

http 协议

git config --global http.proxy http://127.0.0.1:1080
git config --global https.proxy http://127.0.0.1:1080

socks 协议

git config --global http.proxy socks5://127.0.0.1:10808
git config --global https.proxy socks5://127.0.0.1:10808

删除代理

git config --global --unset http.proxy
git config --global --unset https.proxy

ssh 协议代理，配置 ssh config （ Windows ）

Host github.com
    User git
    IdentityFile ~/.ssh/id_rsa
    Port 22
    ProxyCommand connect -S 127.0.0.1:20808 %h %p

ssh 协议代理，配置 ssh config （Linux）

Host github.com
    User git
    IdentityFile ~/.ssh/id_rsa
    Port 22
    ProxyCommand nc -v -x 127.0.0.1:10808 %h %p

ubuntu server 20.04 设置root用户登录

1.设置root密码，已设置的可以往下走

sudo passwd root

2.修改文件

sudo vi /etc/ssh/sshd_config

把 PermitRootLogin without-password 改为 PermitRootLogin yes，注意PermitRootLogin without-password可能被注释掉了，要去掉注释
PS：如果2021.06后的20版本没有找到PermitRootLogin without-password，直接文件末尾添加PermitRootLogin yes即可

3.重启sshd服务

sudo systemctl restart sshd

Docker 安装

安装

如果是个人的开发环境下，推荐使用Docker Desktop，方便又快捷

方式一：使用Docker Desktop 安装

Docker 官网提供桌面安装程序 Docker Desktop，可以根据自己的操作系统选择，Docker Desktop 包含了Docker所有相关组件，方便快捷，但是要注意的是Docker Desktop 的条款。

方式二：使用脚本安装

如果是Linux Server的这类纯命令行系统，Docker 也针对此做了便携式的安装脚本，脚本如下（注意，有些操作系统如果不被支持，可前往官网查看相关文档）：

curl -fsSL https://get.docker.com -o get-docker.sh && sudo sh get-docker.sh && systemctl start docker

上面脚本安装了基本的docker基本组件，如果有docker-compose使用需求的人，按照以下脚本执行即可，下的脚本是基于docker-compose 2.26.1 版本，如果需要特定版本可前往Github下载：https://github.com/docker/compose/releases ，然后自行拆分脚本运行

wget https://github.com/docker/compose/releases/download/v2.29.1/docker-compose-linux-x86_64 -O /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose && sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose && docker-compose --version

镜像加速

如果遇到由于拉取镜像的时间异常的长的话，可以配置镜像加速，可以参考和使用阿里云提供的镜像加速服务。
