mac电脑设置变量开机生效

将变量设置在~/.zshrc后重启即可，
经过尝试，写在~/.bash_profile或/etc/profile文件里时只有使用source时才能临时生效,而写在~/.zshrc文件里时开机即可生效，希望对大家的工作或学习有所帮助。

我电脑上设置的环境变量如下：

menglong@menglong ~ % cat ~/.zshrc
export mvn=/Users/menglong/kafka/apache-maven-3.6.3
export kafka=/opt/kafka_2.12-2.5.0
export zk=/opt/apache-zookeeper-3.6.1-bin
export PATH=$PATH:/opt/jmeter/apache-jmeter-5.3/bin:/usr/local/mysql/support-files:/usr/local/mysql-5.6.41-macos10.13-x86_64/bin:$mvn/bin:$kafka/bin:$zk/bin/:/usr/local/opt/inetutils/libexec/gnubin
