Mac system jdk and maven configuration and mysql configuration

Install the software on the mac and write it in markdown format.

{ QQ, WeChat, email client, chrome git, sourcetree, java 7, idea15, office, sublime editor, mysql workbench, brew, nginx }

1. Install jdk (there are many jdk on Baidu cloud, if the version is incompatible and cannot be installed, download other small versions from the new, such as )

Open i (. Use the touch command to create a .bash_profile file in the ~ directory (user directory),)

Then enter vi .bash_profile

Enter this text: JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/ Home (default jdk installation directory)

Use the :wq command in the vi editor to save and exit

Enter source .bash_profile to make environment variables work

You can echo $JAVA_HOME to see if the path you just configured is output. If the output is successful, it means that your environment variables have been configured.

2. Install maven

a, use the open -e .bash_profile command to open the file, (pro test)

b, use vi to open the file, (not personally tested)

Write the following information in it

MAVEN_HOME=maven installation directory

PATH=$MAVEN_HOME/bin:$PATH

export MAVEN_HOME

export path

/*Pro test

Save the file and exit.

2. Use the source .bash_profile command to make the modified environment variable configuration take effect,

Use the mvn -v command to test whether maven is successfully configured

*/

/* Untested

After pressing the esc key, in the command state: wq exit vi

Vi common operations: esc returns to the normal state, i enters the editing state, :w saves the changes

  2. Find the ~/.m2/ directory, use the "cp source path copy path" command to copy the settings.xml file in the conf directory under the Maven root directory, (the settings file can be searched in the document center)

    And put the path in the local repository specified in the file */

If touch, open and other commands fail, run the command first

export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin to make the command take effect. The reason is that the command is invalid due to wrong environment variable configuration.

I

3, idea configuration maven

The file—otherSetting—defalutSetting command searches for maven, sets the maven installation directory, and the location of the setting file

4.Cloen project

Open http://code.hzchengzi.com/projects/PX to enter a project, there is a menu clone on the left, copy the http URL

(without sourcetree) when idea's own git opens idea, select git to clone a project

Open sourcetree Select Local Clone from URL, enter the copied URL to clone

My .bash_profile file content

M3_HOME=/software/apache-maven-3.2.2

JAVA_HOME=/library/java/javavirtualmachines/jdk1.7.0_79.jdk/Contents/home

PATH=$M3_HOME/bin:$PATH

PATH=$JAVA_HOME/bin:$PATH

export M3_HOME

export JAVA_HOME

export PATH

Chrome browser commonly used plug-in

configured variables are:
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
PATH=$JAVA_HOME/bin:$PATH
MAVEN_HOME=/Users/ zhangkun/work/softfile/apache-maven-3.3.9
PATH=$MAVEN_HOME/bin:$PATH

export JAVA_HOME
PATH=/usr/local/mysql/bin:${PARH}

export PATH



If the terminal command is invalid after configuration, . bash_profile is configured for business trip and needs to be reconfigured.
Enter export PATH=/bin:/usr/bin:/sbin:/usr/sbin to
