尝试使用nginx和Passenger在CentOS 6.5上运行Ruby 2.0.0。到目前为止，由于错误而没有运气：http://prntscr.com/3egoca
这是我用于安装PostgreSQL服务器以与Ruby一起使用的过程：
sudo vi /etc/yum.repos.d/CentOS-Base.repo
# In both [base] and [updates] sections I added the following line to the file above:
# exclude=postgresql*
sudo rpm -Uvh http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-centos93-9.3-1.noarch.rpm
sudo yum install postgresql93 postgresql93-devel postgresql93-server postgresql93-libs postgresql93-contrib
sudo /etc/init.d/postgresql-9.3 initdb
sudo service postgresql-9.3 start
sudo chkconfig --levels 235 postgresql-9.3 on
# At the bottom of this file I changed authentication method to md5:
sudo vi /var/lib/pgsql/9.3/data/pg_hba.conf
sudo service postgresql-9.3 restart
到目前为止，PostgreSQL在测试时效果如此之好，但这就是失败的地方：
bundle install
这给了我错误：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
/home/deploy/.rvm/rubies/ruby-2.0.0-p451/bin/ruby extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
--with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
所以我遵循了这个建议并尝试单独安装PG gem：
gem install pg -- --with-pg-config=/usr/pgsql-9.3/bin/pg_config
当我尝试这个时，我得到了这个输出：
Building native extensions with: '--with-pg-config=/usr/pgsql-9.3/bin/pg_config'
This could take a while...

尽管说成功安装后我仍然收到Passenger错误，但我发布了截图，但仍然无法让bundle install成功运行。
顺便说一句，我是SSH用户＆＃39;部署＆＃39;这也是nginx也被设置为nginx.conf文件中的用户。
答案 0 :(得分：3)
尝试：
export PATH=/usr/pgsql-9.3/bin:$PATH
bundle install
