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 48

                                                                                                                                  
  [ComposerDownloaderTransportException]                                                                                        
  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 48

                                                                                                                                                    
  [ComposerDownloaderTransportException]                                                                                                          
  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）：

 2060  sudo find / -name composer
 2061  sudo rm /usr/local/bin/composer 
 2062  sudo rm /usr/bin/composer 
 2063  rm /tmp/8fc9c56d14b6542c6ff7147207730f6bphar:/usr/bin/composer
 2064  rm -r /tmp/8fc9c56d14b6542c6ff7147207730f6bphar:/usr/bin/composer
 2065  rm -r /tmp/8fc9c56d14b6542c6ff7147207730f6bphar:/usr/bin/composer/vendor/composer
 2066  sudo find / -name composer
 2067  rm /tmp/8fc9c56d14b6542c6ff7147207730f6b/home/www/web/go-study-line/vendor/composer
 2068  sudo rm -r /tmp/8fc9c56d14b6542c6ff7147207730f6b/home/www/web/go-study-line/vendor/composer
 2069  sudo find / -name composer
 2070  rm /home/www/.local/share/composer
 2071  sudo rm -r /home/www/.local/share/composer
 2072  sudo rm -r /home/www/.config/composer/
 2073  sudo rm -r /home/www/.cache/composer/
 # 安装　
 2080  curl -sS https://getcomposer.org/installer | php // 或者 php -r "readfile('http://install.phpcomposer.com/installer');" | php 
 2088  cp composer.phar /usr/local/bin/composer 
 2089  sudo cp composer.phar /usr/local/bin/composer 
 2092  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
