    Welcome to aliyun Elastic Compute Service!

这个阿里云的Ubuntu是14.04.4, 而如果是真正的Ubuntu 系统,可能会16.04.4及其以后 ,内置php为7.0。可能会导致很不顺利。

jdk

command

the mean of optional:

bz2 format  j
gz format    z
c   create
x   unzip
v   detail info
f   file

  • why

    root@iZuf60ahcky4k4nfv470juZ:~/tools/jdk# file jdk-8u101-linux-x64.tar.gz
    jdk-8u101-linux-x64.tar.gz: HTML document, ASCII text, with very long lines, with CRLF line terminators

Well, we download the jdk into local, and then upload it to the Ubuntu server.

$   scp jdk-8u102-linux-x64.tar.gz root@139.196.28.125:/root/tools/jdk
$   tar -zxvf jdk-8u101-linux-x64.tar.gz

root@iZuf60ahcky4k4nfv470juZ:~/tools/jdk# ls
jdk1.8.0_102  jdk-8u102-linux-x64.tar.gz
root@iZuf60ahcky4k4nfv470juZ:~/tools/jdk# mv jdk1.8.0_102 jdk1.8
root@iZuf60ahcky4k4nfv470juZ:~/tools/jdk# ls
jdk1.8  jdk-8u102-linux-x64.tar.gz
  • config jdk env path

1、edit .bashrc

$   vi ~/.bashrc

You can copy the file if necessary cp .bashrc .bash_original

2、add these at the end of file

export JAVA_HOME=/root/tools/jdk/jdk1.8
export CLASSPATH=${JAVA_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

3、make it work at once

$   source ~/.bashrc

4、test jdk

$   java -version

java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

maven

Before this, you need install the jdkfirst.

1、edit .bashrc

$   vi ~/.bashrc

2、append these lines at the file end

# set maven environment
export M2_HOME=/root/tools/maven/apache-maven-3.3.9
export PATH=$M2_HOME/bin:$PATH

3、work at once

$   source ~/.bashrc

4、 test maven

$ mvn --version

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /root/tools/maven/apache-maven-3.3.9
Java version: 1.8.0_102, vendor: Oracle Corporation
Java home: /root/tools/jdk/jdk1.8/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-86-generic", arch: "amd64", family: "unix"

mysql

install mysql

Table name in ubuntu is case sensitive, so. If you want it works like in windows. Just:

add the content under [mysqld], and restart it.

vi /etc/mysql/my.cnf

lower_case_table_names = 1

and then use show variables like 'lower_%'test it:

+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| lower_case_file_system | OFF   |
| lower_case_table_names | 1     |
+------------------------+-------+

1、Start MySQL

service mysql startor /etc/inint.d/mysql start

2、Stop MySQL

service mysql stopor /etc/inint.d/mysql stop

3、Restart MySQL

service mysql restartor /etc/inint.d/mysql restart

  • Uninstall mysql

    service mysql stop
    sudo apt-get autoremove --purge mysql-server-5.0
    sudo apt-get remove mysql-server
    sudo apt-get autoremove mysql-server
    sudo apt-get remove mysql-common

tomcat

add URIEncoding="UTF-8"in conf/server.xmlat:

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

W3m

  • install

    sudo apt-get install w3m w3m-img -y

  • zh_CN

    sudo apt-get install zhcon -y

Useful command

  • restart

    $ reboot

  • get all run threads

    $ ps -ef

  • get version

    $ apt-get install mysql-server-

use double tabto get the version list.

方向键错乱

ubuntu下 vi输入方向键会变成ABCD，这是ubuntu预装的是vim tiny版本，安装vim full版本即可解决。

先卸载vim-tiny：

$ sudo apt-get remove vim-common

再安装vim full：

$ sudo apt-get install vim

22 port

Ubuntu 默认22端口是没有开启的。

ssh: connect to host 192.168.1.105 port 22: Connection refused
lost connection

  • check

    ps -e|grep ssh

啥都没

  • install

    $ sudo apt-get install openssh-server

纯命令行启动

此方法应该只适用于14-*.

blog zh_CN

$ sudo vi /etc/default/grub

修改如下:

  1. 注释 GRUB_CMDLINE_LINUX_DEFAULT

  2. GRUB_CMDLINE_LINUX="" 改成 GRUB_CMDLINE_LINUX="text"

  3. GRUB_TERMINAL=console 注释去除

    #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX="text"

    Uncomment to disable graphical terminal (grub-pc only)

    GRUB_TERMINAL=console

重新生成配置文件

$   sudo update-grub

保持电源关机后仍然运行

修改 Login Manager的配置文件。 打开终端：

$   sudo vi /etc/systemd/logind.conf

然后将其中的：

#HandleLidSwitch=suspend 改成： HandleLidSwitch=ignore

然后重启服务：

$   sudo restart systemd-logind
