将乘客从5.1.12升级到5.20后，Apache乘客停止工作

将Apache module Passenger从5.1.12升级到5.2.0后，Apache无法正确启动并退出，出现错误

# apache2ctl configtest
Invalid command 'PassengerResolveSymlinksInDocumentRoot', perhaps misspelled or defined by a module not included in the server configuration

Apache虚拟主机中的后注释字符串

# PassengerResolveSymlinksInDocumentRoot on

Apache启动了，但Redmine无法显示目录/文件而不是主页（换句话说，找不到索引文件）

操作系统：Ubuntu 14.04.5 LTS

# dpkg -l | grep passenger
ii  libapache2-mod-passenger           1:5.2.0-1~trusty1                                        
ii  passenger                          1:5.2.0-1~trusty1                                        
ii  passenger-dev                      1:5.2.0-1~trusty1                                        
ii  passenger-doc                      1:5.2.0-1~trusty1

所有数据包都是从oss-binaries.phusionpassenger.com安装的

# cat /etc/apt/sources.list.d/passenger.list
deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main

乘客模块已启用

# a2query -m | grep pass
passenger (enabled by site administrator)                                        

我已尝试重新安装乘客（删除并重新安装）

然而，这无助于问题的解决

PassengerResolveSymlinksInDocumentRoot

此选项已在5.2.0版本中根据删除

所以有两种方法可以解决这个问题

1.不要在DocumentRoot中使用符号链接

<VirtualHost *:443>
    ServerName myservername
    DocumentRoot /var/www/redmine
    PassengerAppRoot /opt/redmine/redmine
…
</VirtualHost>

# ls -l /var/www/redmine
lrwxrwxrwx 1 root root 27 Apr 27  2017 /var/www/redmine -> /opt/redmine/redmine/public

2.在虚拟主机Apache中使用参数PassengerAppRoot（如果在DocumentRoot中使用符号链接）

服务器名myservername
DocumentRoot/var/www/redmine
Passengeraproot/opt/redmine/redmine
…
#ls-l/var/www/redmine
lrwxrwxrwx 1根根目录2017年4月27日/var/www/redmine->/opt/redmine/redmine/public

I使用降级版本解决此问题

1） 卸载新版本：

apt-get remove -y passenger libapache2-mod-passenger

2） 安装特定版本：

sudo apt-get install passenger=1:5.1.12-1~trusty1
sudo apt-get install libapache2-mod-passenger=1:5.1.12-1~trusty1
sudo apt-get install passenger-dev=1:5.1.12-1~trusty1

3） 启用apache模块：

sudo a2enmod passenger

4） 重新启动apache：

sudo service apache2 restart

5） 享受
