Linux 命令详解（九）轻易删除OpenSSL 的后果

警告自己，不要轻易的去删除系统的软件

1、composer自动更新出现错误

www@TinywanAliYun:~/web/go-study-line$ composer self-update
Key chrisboulton/php-resque is a duplicate in ./composer.json at line 

  [Composer\Downloader\TransportException]
  The "https://getcomposer.org/versions" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:
  error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
  Failed to enable crypto
  failed to open stream: operation failed                                                                                         

self-update [-r|--rollback] [--clean-backups] [--no-progress] [--update-keys] [--stable] [--preview] [--snapshot] [--set-channel-only] [--] [<version>]

解决办法：

按照百度的：http://www.yiichina.com/tutorial/441，指定的安全证书（重启php服务），还是错误

www@TinywanAliYun:~/web/go-study-line$ composer self-update
Key chrisboulton/php-resque is a duplicate in ./composer.json at line 

  [Composer\Downloader\TransportException]
  The "https://getcomposer.org/versions" file could not be downloaded: failed loading cafile stream: `/usr/share/php/data/Composer/res/cacert.pem'
  Failed to enable crypto
  failed to open stream: operation failed 

最后通过以下步骤解决问题（删除所有的composer，重新安装）：

   sudo find / -name composer
   sudo rm /usr/local/bin/composer
   sudo rm /usr/bin/composer
   rm /tmp/8fc9c56d14b6542c6ff7147207730f6bphar:/usr/bin/composer
   rm -r /tmp/8fc9c56d14b6542c6ff7147207730f6bphar:/usr/bin/composer
   rm -r /tmp/8fc9c56d14b6542c6ff7147207730f6bphar:/usr/bin/composer/vendor/composer
   sudo find / -name composer
   rm /tmp/8fc9c56d14b6542c6ff7147207730f6b/home/www/web/go-study-line/vendor/composer
   sudo rm -r /tmp/8fc9c56d14b6542c6ff7147207730f6b/home/www/web/go-study-line/vendor/composer
   sudo find / -name composer
   rm /home/www/.local/share/composer
   sudo rm -r /home/www/.local/share/composer
   sudo rm -r /home/www/.config/composer/
   sudo rm -r /home/www/.cache/composer/
 # 安装　
   curl -sS https://getcomposer.org/installer | php // 或者 php -r "readfile('http://install.phpcomposer.com/installer');" | php 
  cp composer.phar /usr/local/bin/composer
   sudo cp composer.phar /usr/local/bin/composer 
  sudo ln -s /usr/local/bin/composer /usr/bin/composer

2、Github 授权登陆出现问题

server certificate verification failed.
CAfile: /etc/ssl/certs/ca-certificates.crt
CRLfile: none
