ubuntu 安装之后

[TOC]

参考

1. ubuntu清除多余内核
2. 安装Ubuntu 16.04后要做的事
   ubuntu mysql安装与配置
3. Ubuntu 16.04 安装mysql并设置远程访问
4. mysql5.7 windows7编码统一utf-8
5. Xshell配置ssh免密码登录-密钥公钥(Public key)与私钥(Private Key)登录

首先精简系统

删除libreoffice、删除Amazon的链接、删掉基本不用的自带软件

sudo apt-get remove libreoffice-common 
sudo apt-get remove unity-webapps-common 
sudo apt-get remove thunderbird totem rhythmbox empathy brasero simple-scan gnome-mahjongg aisleriot gnome-mines cheese transmission-common gnome-orca webbrowser-app gnome-sudoku landscape-client-ui-insta

网络设置

openssh允许root远程登陆

vim /etc/ssh/sshd_config

[#]Authentication:
LoginGraceTime 120
PermitRootLogin yes -->改成yes
StrictModes yes

添加中文输入法

sudo apt-get install language-selector language-env language-pack-zh-hans
sudo apt-get install ibus ibus-clutter ibus-gtk ibus-gtk3 ibus-qt4
sudo apt-get install ibus ibus-clutter ibus-gtk ibus-qt4

ubuntu以及衍生版系统如何寻找软件缓存

linux系统默认文件下载位置在/var/cache/apt/archives文件夹下。

ubuntu16.04lts (xenial)安装源

Ubuntu本地软件源制作

sudo apt-get install dpkg-dev
mkdir ~/software
cp -R -v /var/cache/apt/archives/* ~/software
sudo dpkg-scanpackages ~/software /dev/null | gzip >~/software/Packages.gz

编辑/etc/apt/source.list文件

deb file:/home/ubuntu/software ./

更新apt依赖关系

apt-get update && apt-get dist-upgrade

安装软件

关闭bug报告

hadoop@hadoop:~$ sudo vi /etc/default/apport
hadoop@hadoop:~$ cat /etc/default/apport
# set this to 0 to disable apport, or to 1 to enable it
# you can temporarily override this with
# sudo service apport start force_start=1
enabled=0

Ubuntu更新设置

/etc/apt/apt.conf.d/50unattended-upgrades 只需要注释不选择的更新即可

// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
//      "${distro_id}:${distro_codename}-security";
//      "${distro_id}:${distro_codename}-updates";
//      "${distro_id}:${distro_codename}-proposed";
//      "${distro_id}:${distro_codename}-backports";
};

// List of packages to not update (regexp are supported)
Unattended-Upgrade::Package-Blacklist {
//      "vim";
//      "libc6";
//      "libc6-dev";
//      "libc6-i686";
};

临时变量设置（以ADMIN_PASS为例）

export ADMIN_PASS=$(openssl rand -hex 10)

Ubuntus16.04 查看网卡名（ubuntu16.04好像网卡名字不再是eth0 eth1了） ，如下图ens33 ens34即为网卡的名字

Ubuntu16.04 安装时选择LAMP环境，安装完成后如下配置

1. 查看apache版本

root@hadoop:/etc/mysql/mysql.conf.d# apachectl -v
Server version: Apache/2.4.18 (Ubuntu)
Server built:   2016-07-14T12:32:26

2. 允许mysql root远程访问

• 注释/etc/mysql/mysql.conf/mysqld.cnf中的bind-address

[mysqld]
...
#bind-address       = 127.0.0.1

• 登录mysql修改权限表
  登录到mysql服务器，使用grant命令分配权限

mysql> grant all on database_name.* to user_name@'%' identified by 'user_password';

其中database_name、user_name和user_password根据实际情况设置。
