ubuntu做交换机和服务器

ssh

  1. 安装的时候选择openssh server
  2. 初始账户进去后 sudo passwd 配置root密码
  3. /etc/ssh/sshd_config 找到#PermitRootLogin prohibit-password下加PermitRootLogin yes
  4. root可以远程登录
  5. 可能防火墙放行
  6. service ssh restart

多网口桥接

  1. apt-get install bridge-utils安装工具 （brctl工具只能配置临时桥接）
  2. ubuntu 20以后使用Netplan，配置文件在/etc/netplan/*.yuml，之前使用/etc/network/interface
  3. 配置文件
network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: yes
  bridges:
    br0:
      dhcp4: yes
#     dhcp4: no
#     addresses: [10.157.81.250/24]
#     gateway4: 10.157.81.254
#     nameservers:
#        addresses: [114.114.114.114]
      interfaces:
         - enp1s0
         - enp2s0

br0是虚拟网卡 3. 配置路由转发 /etc/sysctl.conf net.ipv4.ip_forward=1 4. sudo netplan apply 应用更改 5. brctl show 查看桥接状态

硬盘挂载

mkfs -t ext4 /dev/xvdb3 格式化成ext4 fdisk -l 查看硬盘设备，

blkid查看并记录uuid

mkdir新建文件夹

vi /etc/fstab

/dev/sda   /mnt/sda   ext4     defaults     0   0
或者
UUID="f7649943-dfdf-4721-92ba-30290bb31d69" /mnt/sda   ext4     defaults     0   0
  1. 第1列是设备名或者卷标
  2. 第2列是挂载点（也就是挂载目录）
  3. 第3列是所要挂载设备的文件系统或者文件系统类型
  4. 第4列是挂载选项， auto: 系统自动挂载，fstab默认就是这个选项 defaults: rw, suid, dev, exec, auto, nouser, and async. noauto 开机不自动挂载 nouser 只有超级用户可以挂载 ro 按只读权限挂载 rw 按可读可写权限挂载 user 任何用户都可以挂载 第5列设置是否使用dump备份，置0为不备份，置1，2为备份，但2的备份重要性比1小 第6列设置是否开机的时候使用fsck检验所挂载的磁盘，置0为不检验，置1，2为检验，但置2盘比置1的盘晚检验 mount -a生效

samba共享

apt-get install samba samba-common 给文件夹权限 chmod 777 /mnt/sda -R 备份sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.bak smb.conf文件最后

[sda]   #共享名
        comment = guest share  #共享描述
        path = /mnt/sda       #共享目录
        public = yes                #允许guest用户访问
        writable = yes              #允许在目录下写入
        directory mask = 0775       #默认创建目录权限 rwxrwxr_x
        create mask = 0775          #默认创建文件权限 rwxrwxr_x
        valid users = heijunma,root  #允许访问该共享的用户
        write list = heijunma,root  #可写入共享的用户列表
        browseable = yes             #该指定共享目录可浏览
        available = yes              #该指定共享资源可使用
        workgroup = DAWN             #设定 Samba Server 所要加入的工作组或者域

service smbd restart

php-fpm配置

nginx配置文件中对phpfpm的配置为：fastcgi_pass 127.0.0.1:9000或fastcgi_pass unix:fastcgi_pass 127.0.0.1:9000;改为fastcgi_pass unix:/tmp/php-fpm.sock; 此项配置在/etc/php/7.4/fpm/pool.d/www.conf中： listen = /run/php/php7.4-fpm.sock； 1. /etc/php/7.4/fpm/php.ini中可以配置

max_execution_time = 3600
max_input_time = 3600
memory_limit = 512M
post_max_size = 512M
upload_max_filesize = 512M
  1. /etc/php/7.4/fpm/pool.d/www.conf中可以配置
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 10
pm.max_spare_servers = 30
pm.max_requests = 500

php-fpm7.4 -t检查配置

多线程bug

imagick 的多线程模式有一個 bug，他会导致多核心的 cpu 使用率瞬间飙升到 100%。所以一定要使用它的单线程程模式才行。重新编译 ImageMagick 最新版，增加了参数：--disable-openmp convert -version 指令查看一下输出內容是否已经开启了多线程 · Features 的值为空或DPC，说明是单线程； · Features的值是 openMP，说明是多线程。

安装yum(可选)

  1. 备份source.list文件，防止弄坏下载源 sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
  2. 更换国内源 sudo vim /etc/apt/sources.list https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/ 第一行添加镜像源 deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse 后面添加清华源
  3. apt-get update apt install python2.7 apt install python-urlgrabber apt install python-sqlitecachec apt-get install yum
  4. ubuntu没有yum源 添加两个repo，在/etc/yum/repos.d下 fedora-163.repo
