這邊有兩個步驟
- 往常我要連入node.js時的網址是http://….:3000/，現在要把它改成http://…./nodejs/
- 永遠保持node.js的伺服器開啟
開始之前我們要安裝環境。
a2enmod proxy a2enmod proxy_http
然後是改網址的部分，這邊我們要動到apache2的設定，所以首先打開 /etc/apache2/sites-available/000-default.conf，我們要加入一個重新導向的部分。
<Location /nodejs>
ProxyPass http://127.0.0.1:3000
ProxyPassReverse http://1127.0.0.1:3000
</Location>
加入後長的是以下這樣。
#/etc/apache2/sites-available/000-default.conf
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg. # It is also possible to configure the loglevel for particular
# modules, e.g. #LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf
######
<Location /nodejs>
ProxyPass http://127.0.0.1:3000
ProxyPassReverse http://1127.0.0.1:3000
</Location>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
然後重啟。
sudo /etc/init.d/apache2 restart
這樣就完成了。
那再來就是永遠保持node.js的伺服器開啟，這邊選用的是forever，一樣我們必須先灌環境。
$ sudo npm install forever -g
然後啟動
forever start app.js
如果是express的情況
forever start ./bin/www.js
然後有幾個會用到的指令
#formate forever stopall #view logs forever logs 0 #detail forever list #restart forever restart
