A detailed description of Linux how to build lamp service environment

Enterprise website construction is bound to be inseparable from the server operation, a stable and efficient server environment is to ensure the normal operation of the site important premise. This article will explain in detail how the Linux system to build a high-efficiency lamp service environment, and in the lamp environment to build up the company's own website.

A brief overview of this article highlights: (Operating system with CentOS6.5 x64)

1. Install lamp service environment respectively;

2. Use lamp to install the package environment with one click;

3. Initially build a website in the lamp environment;

First, the installation of lamp service environment respectively

Preparatory work:

1, configure the firewall, open 80 ports, 3306 ports
Vi/etc/sysconfig/iptables
-A input-m state–state new-m tcp-p tcp–dport 80-j ACCEPT #允许80端口通过防火墙
-A input-m state–state new-m tcp-p tcp–dport 3306-j ACCEPT #允许3306端口通过防火墙

Add the above to the below of the-a input-m state–state new-m tcp-p tcp–dport 22-j ACCEPT

/etc/init.d/iptables Restart #最后重启防火墙使配置生效

2. Turn off SELinux
Vi/etc/selinux/config
#SELINUX =enforcing #注释掉
#SELINUXTYPE =targeted #注释掉
Selinux=disabled #增加
: Wq #保存, close
Shutdown-r now #重启系统

Installation:

1. Installing Apache

Uninstall your own Httpd:yum remove httpd
Yum Install httpd #根据提示, enter Y to install successfully
/ETC/INIT.D/HTTPD Start #启动Apache

Note: Apache will prompt for errors after booting:
Starting httpd:httpd:Could not reliably determine theserver ' s fully qualif domain name, using:: 1 for ServerName
Workaround:
Vi/etc/httpd/conf/httpd.conf #编辑
Found #ServerName www.example.com:80
Modified to ServerName www.osyunwei.com:80 #这里设置为你自己的域名, if no domain name, can be set to localhost
: wq! #保存退出
Chkconfig httpd on #设为开机启动
/ETC/INIT.D/HTTPD Restart #重启Apache

2. Install MySQL

Uninstall your own MySQL first:

Yum remove MySQL mysql-server mysql-libs compat-mysql51
Rm-rf/var/lib/mysql
Rm/etc/my.cnf

Installation:

Yum install MySQL mysql-server #询问是否要安装, enter y for automatic installation until installation is complete
/etc/init.d/mysqld Start #启动MySQL
Chkconfig mysqld on #设为开机启动
CP/USR/SHARE/MYSQL/MY-MEDIUM.CNF/ETC/MY.CNF #拷贝配置文件 (Note: If the/etc directory has a my.cnf under the default, you can directly overwrite it)

To set a password for the root account:
Mysql_secure_installation
Enter, follow the prompts for Y
Enter Password 2 times, enter
Enter Y as prompted
Last appearance: Thanks for using mysql!
MySQL password setup is complete, restart MySQL:
/etc/init.d/mysqld Restart #重启
/etc/init.d/mysqld Stop #停止
/etc/init.d/mysqld Start #启动

3, Installation PHP5
Yum Install PHP
Enter Y as prompted until the installation is complete

Install PHP components to enable PHP5 to support MySQL
Yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pearphp-xml php-xmlrpc php-mbstring php-mcrypt PHP-BC Math Php-mhash Libmcrypt
Select the above installation package here for installation
Enter Y return as prompted
/etc/init.d/mysqld Restart #重启MySql
/ETC/INIT.D/HTTPD Restart #重启Apche

Follow-up installation of Pdo_mysql expansion module, only need: Yum install Php-mysql

Second, the use of lamp one-click installation package to build the environment

Many friends may think that installing Apache, MYDQL, PHP is cumbersome and requires manual configuration. So the next small series to lead you to understand how to use lamp one-click installation package to build a service environment.

Deploying the Lnmp/lamp/lnmpa one-click Package

1. Download the script to extract and perform the installation

wget http://mirrors.linuxeye.com/lnmp-full.tar.gz

Tar xzf lnmp-full.tar.gz

CD LNMP

./install.sh

2, the installation process of the project selection

Because the features of this script are not unattended from the beginning, we need to choose various versions according to our environment, so the selection process is more complicated, we have to see clearly, in this process we install the lamp environment.

(1), upgrade system and port, Web server installation settings

The beginning of the process we see, the official proposal does not update the system, then we do not update. We can directly modify the root port in the process of installing the script directly, this is very good, or we need to modify the port when handling the server security matters, do not use the default 22. Web server installation, because we want to install lamp environment, so nginx does not install, Apache installs its own desired version, I install here 2.4.

(2), database version and PHP version select Install

Here we also choose to install the database and PHP version.

(3) Installation of other related server components

We according to our own site environment requirements environment, configuration needs components, small pieces of personal advice is if you need to use the installation, there is no need to do not install.

Third, some deployment work after the installation is completed

After setting up, then is automatic unattended installation, according to the speed of the system need to execute 20-30 minutes, in short we wait, waiting for the interface to see the installation is complete, we can enter the Y to restart the server, and then detect whether the installation integrity.

We in the server configuration environment still need to do a few work, the most important thing is to delete the default installation of the home page, in the Home/wwwroot/default home page, and the need to modify the directory path phpMyAdmin, the reason we all understand, do not understand also to do.

Third, in the lamp environment to initially build a website

Here we take the mainstream cicada knowledge system for example, directly in just a button installed in the lamp environment to build the site.

Cicada know Enterprise Building Station system download: WWW.CHANZHI.ORG/DOWNLOAD/CHANZHI5.2-126.HTML/?U=XCJ

Cicada Knowledge System User's Manual: HTTP://WWW.CHANZHI.ORG/BOOK/CHANZHIEPS.HTML/?U=XCJ

After the download decompression, the s y S t e M folder is moved to the WWW folder, this www folder is what I will need to upload the site files.

Lamp Environment Add Site:

Because the one-button package is different from the Web panel, we need to add the site command, at least better than the manual deployment, use the following command.

Cd/root/lnmp

./vhost.sh

We will upload the file under WWW to the root directory of the website, visit the website address to install.

Start the Setup program

Access to your domain name http://domain/install.php. If you install the Cicada in the level two directory, you also need to add a level two path.

Check module and directory permissions

Note: If the module or directory check does not pass, follow the instructions given by the system to resolve the issue.

Configuration Database

Note: If you have previously installed a cicada-aware system, you can select the "Empty existing data" button to reinstall it.

Save configuration file

Note: The system will automatically attempt to save the configuration file. If the problem is due to permissions, follow the prompts to copy the contents of the text box, manually saved to the config/my.php file.

set up an administrator account

Login Background

At this point, we have successfully built our website in the lamp environment.
