CENTOS 6.5 new host installation configuration LAMP

Centos6 64bit is automatically installed by Linode. It is very clean and has nothing. It is inevitable to compile things, so first give some compilation environment to yum:

yum install gcc gcc-c++ make flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel openssl-devel libxml2-devel gettext-devel pcre-devel

Modify time zone:

ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

Modify host:

echo 'HOSTNAME=webmaster' >> /etc/sysconfig/network hostname 'webmaster'

Then vim /etc/hosts:

127.0.0.1 localhost.localdomain localhost xx.xx.xx.xx webmaster.onepx.com webmaster

xx.xx.xx.xx is the IP assigned by the VPS on Linode Manager.

Install Apache:

yum install httpd

Apache's configuration file is in /etc/httpd/conf/httpd.conf. If you want to add something to it, it is best to add it to the /etc/httpd/conf.d/ folder and name it x.conf. When Apache starts, it will automatically load all the .conf files in this folder.

Add a domain name, taking onepx.com and the second-level domain name doc.onepx.com as an example. Due to the influence of the previous panel, I am still used to placing the website directory under /home, vim /etc/httpd/conf.d/vhost.conf, add:

NameVirtualHost *:80  ServerAdmin silihai@gmail.com ServerName onepx.com ServerAlias www.onepx.com DocumentRoot /home/onepx/public_html/ ErrorLog /home/onepx/logs/error.log CustomLog /home/onepx/logs/access.log combined   ServerAdmin silihai@gmail.com  ServerName doc.onepx.com ServerAlias ​​www.doc.onepx.com DocumentRoot /home/onepx/public_html/doc/ ErrorLog /home/onepx/logs/doc.error.log CustomLog /home/onepx/logs/doc.access.log combined 

Before starting apache, you need to create a directory according to the above directory structure:

mkdir -p /home/onepx/public_html mkdir /home/onepx/public_html/doc mkdir /home/onepx/logs

Start apache:

/etc/init.d/httpd start

In the future, you need to restart apache after adding a domain name to vhost.con:

/etc/init.d/httpd restart

Let Centos6 automatically start apache when it boots:

/sbin/chkconfig --levels 235 httpd on

Install mysql:

yum install mysql-server

Load mysql when the system starts:

/sbin/chkconfig --levels 235 mysqld on

Start mysql server:

/etc/init.d/mysqld start

The Mysql configuration file is in /etc/my.cnf. The more important thing is to solve the encoding problem. Add the following to solve it once and for all:

[mysqld] character-set-server=utf8 collation-server=utf8_general_ci [client] default-character-set=utf8

Then restart mysql:

/etc/init.d/mysqld restart

run:

mysql_secure_installation

The function is to set the mysql password and delete some default stuff. Then log in:

mysql -u root -p

Create a mysql database and user. The database name is "blog", the user is "onepx", and the password is "password":

create database blog; grant all on blog.* to 'onepx' identified by 'password';

Import an existing database:

use blog; source /home/previous data.sql;

Quit after you're done. For future backups, there is no need to log in to mysql. Under bash:

mysqldump -u onepx -p blog > /home/backup_blog.sql

Start installing PHP below:

yum install php php-pear php-mysql

The PHP configuration file is in /etc/php.ini, and there is also the directory /etc/php.d/. The following .ini files are automatically loaded when starting apache. You can put the added things here and name them xxx.ini. For example, for the eacclerator I want to install below, you should yum it before installing it:

yum install php-gd httpd-devel php-mbstring php-xml php-xmlrpc php-devel

In the past two days, the source on the eaccelerator official website has actually been down... I had to download it elsewhere:

wget http://voxel.dl.sourceforge.net/project/eaccelerator/eaccelerator/eAccelerator%200.9.6.1/ eaccelerator-0.9.6.1.zip unzip eaccelerator-0.9.6.1.zip cd eaccelerator-0.9.6.1 phpize ./configure -enable-eaccelerator=shared make make install

Configure eaccelerator, vim /etc/php.d/eaccelerator.ini, my configuration:

extension='eaccelerator.so' eaccelerator.cache_dir='/tmp/eaccelerator' eaccelerator.check_mtime='1' eaccelerator.compress='1' eaccelerator.compress_level='9' eaccelerator.debug='0' eaccelerator.enable='1' eaccelerator.filter='' eaccelerator.optimizer='1' eaccelerator.shm_max='0' eaccelerator.shm_only='0' eaccelerator.shm_prune_period='0' ; Setting the cache to exceed 32MB will cause apache to fail to start. For details, seeeaccelerator configuration. eaccelerator.shm_size='96' eaccelerator.shm_ttl='600'

Don’t forget:

mkdir /tmp/eaccelerator chmod 777 /tmp/eaccelerator

at last:

/etc/init.d/httpd restart

LAMP installation and configuration completed!
