LAMP=Linux+Apache+Mysql+Php-Linux Operation and Maintenance-php.cn

1. The current mainstream of the InternetwebService

Static service:

1.apache---Small and medium-sized staticwebThe mainstream of services, webThe big brother in the server

2.nginx---Large new network staticwebService mainstream,webNewborn calf in the server

3 .lighttpd---staticwebThe service is tepid, which means it is gradually being eliminated. The community is not active and the efficiency is very high.

Dynamic services:

1.IIS (Internet information services)---Microsoft’s web server (asp、aspx）

2.tomcat---SME NewswebService mainstream, InternetjavaContainer mainstream (jsp,do）

3.resin---Large dynamic websitewebService mainstream, Internet java Container mainstream (jsp, do)

4.php（fcgi）---Large, medium and small websites,php Parsing container of the program

a.With apache, php is not Daemon process, but mod_php5.so(module)

b. Cooperate withnginx,lighttpd, php daemon mode, FCGI mode.

2. Installation of apache

1.First make sure to install httpd Service (yum install httpd -y)

OK: yum install gcc gcc++ zlib zlib-devel -y

2.Installationapache (Address can be found on the official website)

apache Source code compilation:

./configure --prefix=/application/apache2.2.32 \

--enable-expires \

--enable-headers \

--enable-modules=most \

--enable-so \

--with-mpm=worker \

--enable- deflate \

--enable-rewrite

make &&make install

3.Start apache service:

1) Check whether the apache syntax is feasible: [root@localhost local]# /application/apache/bin/apachectl -t

2) Start the apache service: [root@localhost local]# /application/apache/bin/apachectl start

3) Check whether the apache service is started: lsof -i:80 or ps -ef|grep apache

it works indicates success

If notokCheck the port, firewall,selinux, process

straceCommand to trace the process

Modify the compiled content under /application/apache/htdocs/index.html

三、/application/apacheDirectory structure

##apache optimization 1. Put root@localhost conf]# vi Add a - sign in front of the Index in httpd.conf or delete it directly

##/application/apache/conf/extra

Three key files

4. Virtual host

Virtual host: When deploying multiple sites, each site wants to use a different domain name and site directory, or a different port, or a different

IP, a virtual host is required.

In a word, if a

http service needs to configure multiple sites, a virtual machine is required. Virtual machine classification:

a. Based on domain name

b. Based on port

Based on

2. Build a virtual machine (based on domain name)

Filling help tables...

170314 20:15:22 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead .

To start mysqld at boot time you have to copy

support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/application/mysql/bin/mysqladmin -u root password 'new-password'

/application/mysql/bin/mysqladmin -u root -h localhost.localdomain password 'new-password '

Alternatively you can run:

/application/mysql/bin/mysql_secure_installation

which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:

cd /application/mysql ; /application/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl

cd /application/mysql/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /application/mysql/scripts/mysqlbug script!

Startmysql:/application /mysql/bin/mysqld_safe & (When starting the service, please add it to auto-start at boot)

[root@localhost support-files]# netstat -lntup|grep mysql (Confirm whether the service is started)

vi /etc/profile Add the user line at the end

Close:

mysqladmin shutdown

/application/mysql/bin/ mysqladmin -u root -h localhost.localdomain password 'new-password' Set password

mysql -uroot -p (method to log in to mysql after setting password)
