Build lnmp environment in Ubuntu and lnmp in ubuntu
1. Install nginx

Install

Sudo apt-get install nginx

Service start, stop, and restart

/Etc/init. d/nginx start

/Usr/sbin/nginx-c/etc/nginx. conf

/Etc/init. d/nginx stop

/Etc/init. d/nginx restart

Configuration File

/Etc/nginx. conf

Ii. Install MySQL

Installing mysql in Ubuntu is relatively simple.

1. Install the mysql server

Apt-get install mysql-server

During installation, you need to enter the password of the root user.

2. Install the mysql client
Apt-get install mysql-client

3. After installation, you generally need to reset the character set.

1) view the current encoding: show variables like 'character % ';
2) modify my. cnf and add default-character-set = utf8 under [client ].

Command: vi/etc/mysql/my. cnf
3) add default-character-set = utf8, init_connect = 'set NAMES utf8; 'under [server ;'
4) Restart mysql

/Etc/init. d/mysql restart

3. install php

Apt-get install php5-cgi php5-fpm php5-curl php5-gd php5-mysql php5-mcrypt php5-redis

Iv. Configuration

1. configuration files and log files

/Etc/php5/fpm/php. ini php. ini configuration file
/Etc/php5/fpm/php-fpm.conf php-fpm Process Management Master configuration file
/Etc/php5/fpm/pool. d/www. conf php-fpm process pool configuration file
/Var/log/php5-fpm.log php-fpm Error log
/Var/log/php_errors.log php Error log
/Etc/nginx. conf main configuration file
/Etc/nginx/sites-available/default Virtual Host
/Var/log/nginx/access. log nginx access log
/Var/log/nginx/error. log nginx error log

2. php5-fpm Configuration Optimization

/Etc/php5/fpm/pool. d/www. conf

The meanings of the following four parameters are:
Pm. max_children: Number of php-fpm processes enabled in static mode.
Pm. start_servers: number of initial php-fpm processes in dynamic mode.
Pm. min_spare_servers: the minimum number of php-fpm processes in dynamic mode.
Pm. max_spare_servers: Maximum number of php-fpm processes in dynamic mode.

Note: For VPS with a memory of MB, we recommend that you set the following parameters for your reference only:
Pm = dynamic
Pm. max_children = 20
Pm. start_servers = 5
Pm. min_spare_servers = 5
Pm. max_spare_servers = 20

3. nginx Configuration

/Etc/nginx/sites-available/default

Configure and execute the php script on the server node
Location ~ \. Php $ {
# With php5-cgi alone:
# Fastcgi_pass 127.0.0.1: 9000;
# With php5-fpm:
Fastcgi_pass unix:/var/run/php5-fpm.sock;
Fastcgi_index index. php;
Include fastcgi_params;
}

4. php Error Log

/Etc/php5/fpm/php. ini
Log_errors = On
Error_log =/var/log/php_errors.log

5. Restart php-fpm and nginx

Sudo/etc/init. d/php5-fpm restart
Sudo/etc/init. d/nginx restart
