homebrew,搞了一天终于把这个 tomcat 给装上了!

今天用到 tomcat,然后发现自己的版本是 8,而最新版本已经是 9 了,想着就用最新的. 卸载了 8 然后悲剧了,一直安装不了,摸了一天鱼,终于搞定了,记录一下!

1.下载 tomcat,发现一直失败

dashudeMacBook-Pro:~ dashu$ brew install tomcat
==> Downloading https://www.apache.org/dyn/closer.cgi?path=/tomcat/tomcat-9/v9.0.24/bin/apache-tomcat-9.0.24.tar.gz
==> Downloading from http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.24/bin/apache-tomcat-9.0.24.tar.gz

curl: (22) The requested URL returned error: 404 Not Found
Trying a mirror...
==> Downloading https://www-eu.apache.org/dist/tomcat/tomcat-9/v9.0.24/bin/apache-tomcat-9.0.24.tar.gz
^C^C
dashudeMacBook-Pro:~ dashu$

2.看下了输出,奇怪,为什么国内镜像不行,反而转欧美镜像了(有墙下载不下来很正常啊!)

于是去看下国内镜像,果然,国内镜像确实不存在

试着访问了镜像地址:https://www.apache.org/dyn/closer.cgi?path=/tomcat/tomcat-9/v9.0.24/bin/apache-tomcat-9.0.24.tar.gz

3.那就按照提示用 9.0.27 版本呗,想着指定 url 下载吧!

结果还是悲剧...百度之,ruby 字符解析问题?(我不会 ruby 语法啊,搞不懂)

dashudeMacBook-Pro:~ dashu$ brew install "https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.27/bin/apache-tomcat-9.0.27.tar.gz"
######################################################################## 100.0%
######################################################################## 100.0%
Error: apache-tomcat-9.0.27.tar.gz: /Users/dashu/Library/Caches/Homebrew/Formula/apache-tomcat-9.0.27.tar.gz:1: Invalid char `\x1F' in expression
/Users/dashu/Library/Caches/Homebrew/Formula/apache-tomcat-9.0.27.tar.gz:1: invalid multibyte char (UTF-8)

4.搜索了半天 ruby “invalid multibyte char”,毫无头绪···.(中间也试了很多其他猜想,不赘述了)

我还真不信了,一直都是通过 homebrew 安装软件的啊.于是想前向不行,后向试试? 试着安装 7,诶!还真行~

dashudeMacBook-Pro:~ dashu$ brew install tomcat7
==> Downloading https://www.apache.org/dyn/closer.cgi?path=tomcat/tomcat-7/v7.0.96/bin/apache-tomcat-7.0.96.tar.gz

==> Caveats
tomcat@7 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have tomcat@7 first in your PATH run:
  echo 'export PATH="/usr/local/opt/tomcat@7/bin:$PATH"' >> ~/.bash_profile


To have launchd start tomcat@7 now and restart at login:
  brew services start tomcat@7
Or, if you don't want/need a background service you can just run:
  catalina run
==> Summary
🍺  /usr/local/Cellar/tomcat@7/7.0.96: 634 files, 13.6MB, built in 14 seconds

5.到这里,朋友们回觉得:终于安装好 tomcat 了,任务完成!可以继续安心摸鱼···但楼主决不是求安逸的人,一定要搞明白 WHY!

灵机一动,brew 其实运行的是 git 仓库里的 ruby 脚本,这样看来莫不是仓库里的代码不是最新的? 于是 brew update 搞起

dashudeMacBook-Pro:~ dashu$ brew update
fatal: unable to access 'https://github.com/Homebrew/homebrew-cask/': LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
fatal: unable to access 'https://github.com/Homebrew/homebrew-core/': LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask failed!
Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core failed!
Updated 1 tap (homebrew/cask-versions).
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home
No changes to formulae.

6.哦吼,问题就是它--更新不了 ruby 脚本!

百度之,やっぱり！需要将 git 远程仓库地址也修改成国内镜像,解决方案简单,修改之.

cd "$(brew --repo)" 
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" 
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

7.再试一次“brew update”.完美,更新成功

dashudeMacBook-Pro:homebrew-core dashu$ brew update
Updated 2 taps (homebrew/core and homebrew/cask).
==> New Formulae
...(其他更新内容太多,就不贴了)
