1. Update
www.jb51.net
Copy code The code is as follows:
sudo apt-get update
2. Install nginx
Copy code The code is as follows:
sudo apt-get intsall nginx
The file structure after Ubuntu installation is roughly:
* All configuration files are under /etc/nginx, and each virtual host has been arranged under /etc/nginx/sites-available www.jb51.net
*Program files are in /usr/sbin/nginx * Logs are placed in /var/log/nginx
* and have created the startup script nginx
under /etc/init.d/
* The default virtual host directory is set to /var/www/nginx-default
You can start nginx below to see the effect (please make sure that no other services are using port 80):
Copy code The code is as follows:
sudo /etc/init.d/nginx start
# or simply
Copy code The code is as follows:
service nginx start
Then open the browser and check http://localhost/ to see if you see "Welcome to nginx!" If you see it, the installation is successful.
Of course, basically, there will be no problems with this. If the operation fails, you can first
Copy code The code is as follows:
sudo killall apache2
Kill the apache process
3. Install php
Copy code The code is as follows:
sudo apt-get install php5 php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-pspell php5-recode php5- snmp php5-tidy php5-xmlrpc php5-sqlite php5-xsl
4. Install spawn-fcgi
Why should you install spawn-fcgi? It is used to control the php-cgi process to prevent the process from crashing or the efficiency of a single process being too low.
Many people on the Internet say that to use spawn-fcgi, you must install lighttpd. In fact, it is not necessary. You can install spawn-fcgi directly
Run:
Copy code The code is as follows:
sudo apt-get install spawn-fcgi
5. Configuration
The next step is the most troublesome configuration.
Configure Nginx and spawn-fcgi to run together
(1). At the end of the /etc/nginx/fastcgi_params file, add a line, you can use
sudo vi /etc/nginx/fastcgi_params
Join this trip:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
(2). In addition, you need to find the cgi.fix_pathinfo option in the PHP-CGI configuration file (this configuration file is located in /etc/php5/cgi/php.ini on Ubuntu) and modify it to:
cgi.fix_pathinfo=1;
This way php-cgi can use the SCRIPT_FILENAME variable normally.
(3). Open the /etc/nginx/sites-available/default file in
server { listen 80; server_name localhost;
Add the absolute address of the web root directory below. The default address of nginx is used here
root /var/www/nginx-default
That is, root and server_name are at the same level, which is equivalent to the default directory of apache
Without this, when executing the php file, it is easy to prompt "No input file specified".
I went through a lot of circles here before I found the problem. Then I modified it
#location ~ .php$ {
#fastcgi_pass 127.0.0.1:9000;
#fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
#includefastcgi_params;
#}
was changed to
location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;
include /etc/nginx/fastcgi_params; #Include fastcgi parameter file address
6. Start the fast_cgi process
sudo /usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid
7. Set up the fastcgi process at boot and start it
sudo vi /etc/rc.local
Add next line
/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid
If you open a php file and it appears: No input file specified, please check the configuration of php.ini
cgi.fix_pathinfo=1
doc_root=
Also, each virtual machine must set up a different directory according to its different virtual machines, and ensure that the path is correct.
Check the configuration file under /etc/nginx/sites-available. The server contains root and address, not the root in location
Start
fast-cgisudo /usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid
The meaning of parameters is as follows
* -f specifies the execution program location of the process that calls FastCGI, and sets it specifically according to the PHP installed on the system
* -a bind to address addr
* -p bind to port port
* -s Path path bound to unix socket
* -C specifies the number of FastCGI processes generated, the default is 5 (only for PHP)
* -P specifies the PID file path of the generated process
* What identity does -u and -g FastCGI use to run (-u user-g user group)? You can use www-data under Ubuntu. Others are configured according to the situation, such as nobody, apache, etc. You can now put a probe in the web root directory Or php file to test it
8. Install mysql
sudo apt-get install mysql-server mysql-client
You will be prompted to enter the Root user password in the middle, just enter it in sequence.
Start MySQL
sudo /etc/init.d/mysql start
Test whether the mysql service is normal:
Run
mysql -uroot -p
Enter mysql password
show databases;
If you see the following content
| Database |
| information_schema |
| mysql |
Then mysql has been installed correctly.
At this point, the installation of nginx+php+mysql under ubuntu is completed.
