系統(tǒng)中的nginx是這樣安裝的sudoapt-getinstallnginx安裝了passenger后geminstallpassenger還需安裝nginxmodule才能在nginx中配置使用它。在安裝時passenger-install-nginx-module提示AutomaticallydownloadandinstallNginx?Nginxdoesn'tsupportloadablemodulessuchassomeotherwebserversdo,soinordertoinstallNginxwithPassengersupport,itmustberecompiled.Doyouwantthisinstallertodownload,compileandinstallNginxforyou?1.Yes:download,compileandinstallNginxforme.(recommended)Theeasiestwaytogetstarted.AstockNginx1.4.4withPassengersupport,butwithnootheradditionalthirdpartymodules,willbeinstalledforyoutoadirectoryofyourchoice.2.No:IwanttocustomizemyNginxinstallation.(foradvancedusers)ChoosethisifyouwanttocompileNginxwithmorethirdpartymodulesbesidesPassenger,orifyouneedtopassadditionaloptionstoNginx's'configure'script.Thisinstallerwill1)askyouforthelocationoftheNginxsourcecode,2)runthe'configure'scriptaccordingtoyourinstructions,and3)run'makeinstall'.Whicheveryouchoose,ifyoualreadyhaveanexistingNginxconfigurationfile,thenitwillbepreserved.【問題1】這樣再次安裝nginx的話，和原來的版本沒有沖突嗎？直接安裝的nginx的啟動方法是sudoservicenginxstartsudoservicenginxrestartsudoservicenginxstop通過passenger-install-nginx-module安裝的nginx的啟動方法是sudonginxsudonginx-sreloadsudonginx-sstop【問題2】為什么會有這樣的區(qū)別呢？【問題3】在已經(jīng)存在nginx的系統(tǒng)中，有其它方式安裝passenger的nginxmodule嗎？
