LAMP differs from LNMP in:

Advantages of the 1.LNMP approach:

It takes up less resources, and Nginx is relatively simple to configure. Fast-cgi is used to dynamically parse PHP scripts. Disadvantages: the load capacity of php-fpm components is limited, when the traffic is large, the php-fpm process is easy to freeze, prone to 502 bad gateway errors.

two。 The design based on LAMP architecture has the characteristics of low cost, flexible deployment, rapid development, security and stability, and is an excellent combination of Web network applications and environment.

If the server configuration is relatively low for personal websites, LNMP architecture is of course the first choice. Of course, when there is a lot of traffic. It is also a good choice to combine Apache with Nginx.

In 3.LNMP architecture, php starts the service php-fpm, while php in LAMP only exists as a module of Apache.

Nginx will pass the user's dynamic request to the php service for processing, and the php service will interact with the database. Users' static requests will be processed directly by Nginx, and Nginx handles static requests much faster than Apache, so there is little difference between apache and Nginx in dynamic request processing, but if it is static processing, you will find that Nginx is faster than apache, and Nginx can withstand more concurrency than apache, and can withstand tens of thousands of concurrent connections, so larger websites will use Nginx as the web server.

The difference between Apache+php and nginx+php:

1. Apache generally starts php as a module of its own, while nginx forwards http request variables to the php process, that is, php independent process, to communicate with Nginx, which is called fast-cgi operation mode, so php compiled by apache cannot be used in nginx.

Brief description:

LNMP platform is the combined architecture of Linux,Nginx,MySQL,PHP, which requires Linux server, Nginx website server, MySQL database and PHP parsing environment.

Details

Linux is a kind of Unix computer operating system, which is the most popular free operating system at present. Nginx is a high-performance HTTP and reverse proxy server, lightweight, with high concurrent processing power Mysql is a small relational database management system. PHP is a scripting language that embeds HTML documents executed on the server side.

The experiment begins.

1. Use remote sharing on Linux to obtain the source code package from Windows sharing

[root@localhost ~] # smbclient-L / / 192.168.235.1 / # # remote share access Enter SAMBA\ root's password: Sharename Type Comment-LNMP Disk [root@localhost ~] # mkdir / abc [root@localhost ~] # mount.cifs / / 192.168.235.1/LNMP / abc # # Mount to / abc directory Install nginx

2. Decompression

[root@localhost ~] # cd / abc # # switch to the mount point directory [root@localhost abc] # lsDiscuz_X3.4_SC_UTF8.zip nginx-1.12.2.tar.gzmysql-boost-5.7.20.tar.gz php-7.1.10.tar.gz [root@localhost abc] # tar zxvf nginx-1.12.2.tar.gz-C / opt # # decompress the Nginx source code package to [root@localhost abc] # cd under / opt / opt/ # # switch to [root@localhost opt] # lsnginx-1.12.2 rh under the decompressed directory

3. Install the environment package

[root@localhost opt] # yum-y install\ gcc\ / / c language gcc-c++ / / C++ language pcre-devel\ / / pcre language tool zlib-devel / / data compression function library

4. Create program users and configuration file parameters

[root@localhost opt] # useradd-M-s / sbin/nologin nginx # # Creator user Limit its [root@localhost opt] # cd nginx-1.12.2/ # # switch to [root@localhost nginx-1.12.2] #. / configure\ # # configure nginx >-- prefix=/usr/local/nginx\ # # installation path >-- user=nginx\ # # user name >-- group=nginx\ # # user groups >-- with-http_stub_status_module # # access status Statistics Module

5. Compile and install

[root@localhost nginx-1.12.2] # make & & make install

6. Optimize the Nginx service startup script and establish command soft links

[root@localhost nginx] # ln-s / usr/local/nginx/sbin/nginx / usr/local/sbin/ # # create a soft connection to let the system recognize the nginx startup script [root@localhost nginx] # nginx-t # # check the syntax problems of the configuration file nginx: the configuration file / usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file / usr/local/nginx/conf/nginx.conf test is successful [root@localhost nginx] # nginx # # Open ngnix [root@localhost nginx] # netstat-ntap | grep 80 # # View port Nginx has enabled tcp 0 0 0.0.0.0 LISTEN 39620/nginx: master [root@localhost nginx] # systemctl stop firewalld.service # # turn off firewall [root@localhost nginx] # setenforce 0 [root@localhost nginx] # nginx # # enable nginx service

7. Make service management nginx script

[root@localhost nginx] # cd / etc/init.d/ # # switch to the startup configuration file directory [root@localhost init.d] # lsfunctions netconsole network README [root@localhost init.d] # vim nginx # # Edit the startup script file #! / bin/bash # chkconfig:-99 20 # # comment Information # description: Nginx Service Control Script PROG= "/ usr/local/nginx/sbin/nginx" # # set the variable to the nginx command file PIDF= "/ usr/local/nginx/logs/nginx.pid" # # set the variable PID file process number is 5346 case "$1" in start) $PROG # # start the service ; stop) kill-s QUIT $(cat $PIDF) # # disable the service;; restart) # # restart the service $0 stop $0 start Reload) # # reload service kill-s HUP $(cat $PIDF) *) # # incorrect input prompt echo "Usage: $0 {start | stop | restart | reload}" exit 1 esac exit 0 [root@localhost init.d] # chmod + x / etc/init.d/nginx # # Grant startup script execution permission [root@localhost init.d ] # chkconfig-- add nginx # # add to service Manager [root@localhost init.d] # service nginx stop # # stop the nginx service using service [root@localhost init.d] # service nginx start # # start the nginx service using service

8. Systemctl manages nginx scripts

[root@localhost ~] # vim / lib/systemd/system/nginx.service # # create a profile [Unit] Description=nginx # # describe After=network.target # # describe the service type [Service] Type=forking # # background running form PIDFile=/usr/local/nginx/logs/nginx.pid # # PID file location ExecStart=/usr/local/nginx/sbin/nginx # # start the service ExecReload=/usr/bin/kill-s HUP $MAINPID # # configure ExecStop=/usr/bin/kill-s QUIT $MAINPID # # according to PID overload to terminate the process PrivateTmp= true [install] WantedBy=multi-user.target [root@localhost ~] # chmod according to PID 754 / lib/systemd/system/nginx.service # # set execution permission [root@localhost ~] # systemctl stop nginx.service # # close nginx [root@localhost ~] # systemctl start nginx.service # # enable 2. Install MySQL

9. Install the environment components

24. Use the host to test the web page

25. Enter the database to create the bbs database and set the administrator and password

[root@localhost etc] # mysql-u root-pEnter password: # # enter the database with the password of abc23mysql > CREATE DATABASE BBS; # # create bbs database Query OK, 1 row affected (0.00 sec) mysql > GRANT all ON bbs.* TO 'bbsusers'@'%' IDENTIFIED BY' admin123' # # upgrade database user bbsuser as administrator and set password Query OK, 0 rows affected, 1 warning (0.00 sec) mysql > GRANT all ON bbs.* TO 'bbsusers'@'localhost' IDENTIFIED BY' admin123';Query OK, 0 rows affected, 1 warning (0.00 sec) mysql > flush privileges # # Refresh database Query OK, 0 rows affected (0.00 sec) mysql > quit # # exit [root@localhost etc] # vim / usr/local/nginx/html/index.php # # Test database connection status [root@localhost etc] # systemctl restart nginx.service # # restart service

26. Refresh and test the web page again

At this point, the deployment of LNMP architecture is complete!
