homebrew,搞了一天终于把这个 tomcat 给装上了!

[jyounn]

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
==> Downloading from http://mirrors.tuna.tsinghua.edu.cn/apache/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)

8.见证奇迹的时刻.-)

希望能帮助遇到同样问题的小伙伴们.

第一次发帖,还不是上图...大家见谅

[zhoulouzi]

Good

[julyclyde]

我提炼一下：
tuna 已经不提供 9024 了
你想办法更新了 brew 之后，开始下载 9027

[jyounn]

@julyclyde 大佬总结得很精屁

[julyclyde]

@jyounn 第一遍没看懂，又仔细看了一遍
然后猜想估计别人也跟我第一遍一样，干脆总结一下

[efaun]

docker 大法好

[jyounn]

@julyclyde 😓看来以后开头应该先总结一句

[jyounn]

@efaun 这和用啥没关系吧.虽然没研究过 docker,但是原理应该一样,需要不定期更新?

[efaun]

@jyounn #8 docker 一键部署了呗，不用配置了

[jyounn]

@efaun 了解了下,docker 是应用容器管理工具.和 homebrew 这个包管理工具功能不太一样吧.

[efaun]

@jyounn #10 我的意思是，你自己安装 tomcat，相当于安装一个软件不停点下一步，用 docker，相当于绿色软件下载即用，当然这也看个人喜好，也有人就是享受自己配置的感觉

[jyounn]

@efaun 好嘞

遇到相同的问题，最后发现是版本更新后 brew 的信息没有更新，下载失败。可以 brew edit tomcat 修改，然后再装。
不确定如何修改，比如，可以先 brew bump-formula-pr --url=http://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.31/bin/apache-tomcat-9.0.31.tar.gz tomcat，然后可以在 https://github.com/Homebrew/homebrew-core/pulls 看到提交的 pr，按照 pr 修改即可。

[xmsec]

上面这个方法针对 brew update 之后也无法安装的情况，因为软件更新后 brew 的仓库信息还没有来得及更新。
