1. Basic knowledge of LAMP combination

II. Installation of WordPress and phpmyadmin

LAMP

Linux

Apache (httpd)

MySQL

Php, Python, perl, ruby, etc.

Combination of An and P:

CGI:common gateway interface universal gateway interface, which can be understood as a simplified version of http protocol, which is used for communication between web server and php application process.

Client-- > web server-- > php-- > web server--client;php process generation and destruction are maintained by web server, so web server is very busy and inefficient

Fast CGI: fast CGI, its principle is the same as CGI (client-> web server-- > php-- > web server--client)

But the difference is that when web server starts, it starts a fastcgi manager, such as phpfpm, and starts multiple processes containing php interpreters at the same time, thus forming a process pool managed by phpfpm, so that when web server receives a request, phpfpm dispatches a process to execute, and the process continues to return to the phpfpm process pool without destroying after execution. Performance is improved by omitting the fork destory process

To put it simply, like httpd, php generates multiple process listeners on the specified socket. It is an independent service. Httpd receives the request, sends it to the php process through the protocol, exchanges httpd after execution by php, and finally httpd encapsulates it to the client. The advantage is that web server and php server can be separated and deployed in multiple servers.

Module:client-- > web server-- > client, because php is already a module of httpd that contains a php interpreter and can execute php

FASTCGI and MODULE: both modes have the concept of process pool, and their performance is higher than that of CGI. The difference is that one process pool is the process pool of web server and the other is the process pool of php. In FASTCGI mode, dynamic and static requests can be better separated, and problems in php will not affect web server.

Amp combination in centos6 (rpm package):

Httpd is generally already installed

# yum install httpd outline

Install php

# yum install php

[root@www ~] # rpm-ql php

/ etc/httpd/conf.d/php.conf

/ usr/lib64/httpd/modules/libphp5.so

/ var/lib/php/session

/ var/www/icons/php.gif

As you can see, httpd is combined in a modular way.

Install mysql-server

# yum install mysql-server

Mysql is a CS program, so the installation server should be specified when installing. However, the MySQL client has dependencies, so it will be installed as well

The service of the service mysqld start MySQL program is called mysqld, which is a separate service program.

Install php-mysql

This is a driver interface for php to connect to mysql

Blog assignment:

Rpm package format installation configuration lamp, which provides two virtual hosts, one for WordPress and one for phpmyadmin, and provides ssl access for the latter

Since we have previously experimented with www.aaa.com www.bbb.com two virtual hosts, in which www.bbb.com provides ssl access, we will now modify it:

Www.aaa.com content is WordPress

Www.bbb.com is phpmyadmin and provides ssl access

1. WordPress part:

/ etc/httpd/conf.d/aaa.conf content:

ServerAdmin webadmin@aaa.com

DocumentRoot / web/vhosts/aaa.com/

ServerName www.aaa.com

ServerAlias aaa.com

ErrorLog / var/log/httpd/aaa.err

CustomLog / var/log/httpd/aaa.access combined

So delete the original default home page and add a new test

Create a new test.php in / web/vhosts/aaa.com/ with the following contents:

Test the connection between php and mysql

Test php version and other information:

Note that if index.php ends with .php, if it is written as html, the code will not run, it can recognize the suffix execution; test OK~

Download WordPress and extract it (brief process)

[root@www aaa.com] # ls

Index.php wordpress wordpress-4.5.2-zh_CN.zip

[root@www aaa.com] # rm index.php

Rm: do you want to delete the normal file "index.php"? Y

[root@www aaa.com] # mv wordpress/*.

[root@www aaa.com] # ls

Index.php wordpress wp-admin wp-config-sample.php wp-includes wp-login.php wp-signup.php

License.txt wordpress-4.5.2-zh_CN.zip wp-blog-header.php wp-content wp-links-opml.php wp-mail.php wp-trackback.php

Readme.html wp-activate.php wp-comments-post.php wp-cron.php wp-load.php wp-settings.php xmlrpc.php

[root@www aaa.com] #

The default mysql does not have a password, so the password is arbitrary because it is a test

Mysql > SET PASSWORD FOR 'root'@'localhost' = PASSWORD (' 1qazXSW')

Open the web page and start installing WordPress

Database name: wordpress

User name: root

Password: 1qazXSW@

Database host: localhost

Table prefix: wp_

There will be an error in the installation process because the database WordPress does not exist. Create:

[root@www aaa.com] # mysql-uroot-p123456

Welcome to the MySQL monitor. Commands end with; or\ g.

Your MySQL connection id is 5

Server version: 5.1.73 Source distribution

Type 'help;' or'\ h' for help. Type'\ c'to clear the current input statement.

Mysql > create database wordpress; # # create a database

Query OK, 1 row affected (0.00 sec)

Mysql >

In fact, you can also modify wp-config.php to set the database, user name, password, etc., but to create these in advance, you are not very good at mysql, so use the installation wizard to create them automatically.

There will also be errors in the process, unable to write to the file, and modify permissions:

[root@www vhosts] # chmod 777-R aaa.com

If nothing happens, it is now a "Welcome" to set the site title, user name, password and other information. "install WordPress" after completion

2. Phpmyadmin section, and use ssl to access

Modify / etc/httpd/conf.d/ssl.conf, modify part:

DocumentRoot "/ web/vhosts/bbb.com/phpmyadmin/" # # Home page path

ServerName www.bbb.com:443 # # servername of the site

ErrorLog logs/ssl_error_log # # error log storage path

TransferLog logs/ssl_access_log # # access log storage path

LogLevel warn

SSLCertificateFile / etc/httpd/ssl/http.crt # # Certificate path

SSLCertificateKeyFile / etc/httpd/ssl/http.key # # key path

Because there was a ssl test before, the previous certificates and keys can continue to be used.

In the course of the experiment, we downloaded the latest version of phpMyAdmin-4.6.1-all-languages, prompting PHP 5.5 + is required. Currently installed version is: 5.3.3

Hint requires a version above php5.5, the current version is 5.3.3. So I downloaded phpMyAdmin 4.0.10.15 again, which can be used normally.

If the mbstring,yum installation php-mbstring cannot be found, reread the httpd configuration file or restart the httpd service.

Complain about the cheetah, use the cheetah browser to open the account password, can not log in and there is no error prompt, change the Google browser can log in normally.
