# include .bashrc if it exists
if [ -f "/data/Dev/Pro/start/mario_path" ]; then

2.添加相应位置的工具包
3.自定义环境变量内容（先看文件地址）
# mario_path 内容，基本上都是类似的样式
# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)

# Description: MySQL is a very fast and reliable SQL database engine.
### END INIT INFO
# If you install MySQL on some other places than /usr/local/mysql, then you
# have to do one of the following things for this script to work:
#
# - Run this script from within the MySQL installation directory
# - Create a /etc/my.cnf file with the following information:
# [mysqld]
# basedir=
# - Add the above to any other configuration file (for example ~/.my.ini)
# and copy my_print_defaults to /usr/bin
# - Add the path to the mysql-installation-directory to the basedir variable
# below.
#
# If you want to affect other MySQL variables, you should make your changes
# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.

1.添加脚本，导入自定义环境变量
2.添加相应位置的工具包
3.自定义环境变量内容（先看文件地址）
# mario_path 内容，基本上都是类似的样式
3.mysql 和 redis 得手动启动，上面最后一个环境地址的设置目的
# mario 文件的内容，目的是快捷启动mysql 和 redis 服务，同目录下的那两个 init 文件
