Build WEB + NFS + DNS in CentOS

Build WEB + NFS + DNS in CentOS

This experiment uses two web, a php and mysql web1, 2 (172.16.31.30, 31.31) nfs 172.16.31.34

Php 172.16.31.32 mysql 172.16.31.32

Build

1. Set up web

First # mount-t nfs 172.16.31.34:/mydata mount nfs

The web version used in this compilation and the previous LAMP is the same.

1. Download the three packages of apr-1.5.0.tar.bz2 apr-util-1.5.3.tar.bz2 httpd-2.4.9.tar.bz2, extract them in turn,

# Tar xf apr-1.5.0.tar.bz2

# Cd apr-1.5.0

#./Configure -- prefix =/usr/local/apr

# Make & make install

2) Compile and install apr-util

# Tar xf apr-util-1.5.3.tar.bz2

# Cd apr-util-1.5.3

#./Configure -- prefix =/usr/local/apr-util -- with-apr =/usr/local/apr

# Make & make install

3) Compile and install httpd-2.4.9

# Tar xf httpd-2.4.9.tar.bz2

# Cd httpd-2.4.9

#. /Configure -- prefix =/usr/local/apache -- sysconfdir =/etc/httpd24 -- enable-so -- enable-ssl -- enable-cgi -- enable-rewrite -- with-zlib -- -pcre -- with-apr =/usr/local/apr -- with-apr-util =/usr/local/apr-util -- enable-modules = most -- enable-mpms-shared = all -- with-mpm = event

# Make & make install

Both of them perform this operation, and then modify the PATH environment variable.

Echo "export PATH =/usr/local/apach/bin: $ PATH">/etc/profile. d/httpd. sh

Make the PATH take effect in the current shell and start the service

Source/etc/profile. d/httpd. sh

Apachectl start

# Vim/etc/httpd. con

LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so two modules to be enabled

LoadModule proxy_module modules/mod_proxy.so

ServerName www.caoshujia.com: 80

ProxyRequests off disable forward proxy

ProxyPassMatch ^/(. * \. php) $ fcgi: // 172.16.2.11: 9000/mydata/$1 any php file uses the fcgi protocol to proxy to the php server.

DocumentRoot "/mydata/" to change the root directory of the site to nfs

<Directory "/mydata/"> modify the control label for the root Directory of the site

DirectoryIndex index.html index. php add default request file

AddType application/x-httpd-php. php is added to the <IfModule mime_module> label to support php files.

AddType application/x-httpd-php-source. phps

# Httpd-t

# Apache restart

2 php compilation and Installation

1) install several packages in advance. If yes, no installation is required.

# Yum-y groupinstall "Desktop Platform Development"

# Yum-y install bzip2-devel

# Yum-y install libmcrypt-devel

2) Compile and install

# Tar xf php-5.4.26.tar.bz2

# Cd php-5.4.26

#. /Configure -- prefix =/usr/local/php -- with-mysql -- with-mysqli -- with-openssl -- enable-mbstring -- with-freetype-dir -- with-jpeg-dir -- with-png-dir -- with-zlib -- with-libxml-dir -- enable-xml -- enable-sockets -- enable-fpm -- with-bz2 -- with-config-file-path =/etc -- with-config-file-scan-dir =/etc/php. d -- with-mcrypt

# Make & make install

3) provide a configuration file for php:

# Cp php. ini-production/etc/php. ini

4) Configure php-fpm

Provide the SysV init script for php-fpm and add it to the service list:

# Cp sapi/fpm/init. d. php-fpm/etc/rc. d/init. d/php-fpm

# Chmod + x/etc/rc. d/init. d/php-fpm

# Chkconfig -- add php-fpm

# Chkconfig php-fpm on

Provide configuration files for php-fpm:

# Cp/usr/local/php/etc/php-fpm.conf.default/usr/local/php/etc/php-fpm.conf

Edit the configuration file of php-fpm:

# Vim/usr/local/php/etc/php-fpm.conf

Configure fpm related options for your required values and enable the pid file (the last line below ):

Pm. max_children = 50

Pm. start_servers = 5

Pm. min_spare_servers = 2

Pm. max_spare_servers = 8

Pid =/usr/local/php/var/run/php-fpm.pid

Specifies the location of the php PID file. This line must be written in the first line under [global], otherwise it will not take effect.

Next we can start php-fpm:

# Service php-fpm start

Detection listening port

# Netstat-tnlp | grep php-fpm

Tcp 0 0 127.0.0.1: 9000 0.0.0.0: * LISTEN 689/php-fpm

[Root @ localhost php-5.4.26] # service php start

[Root @ localhost php-5.4.26] # mkdir/mydata

[Root @ localhost php-5.4.26] # mount-t nfs 172.16.31.34:/mydata mount nfs to store php pages.

[Root @ localhost php-5.4.26] # chown-R nobody/mydata modify the owner of the webdata directory to nobody because nobody is the user running the php process.

3. mysql Configuration

Export to/usr/local

[Root @ localhost ~] # Tar xfmariadb-5.5.36-linux-x86_64.tar.gz-C/usr/local

2. File System for data storage preparation

A creates an sda3

[Root @ localhost ~] # Fdisk/dev/sda

Command (m for help): n

Device-mapper: reload ioctl on sda1failed: Invalid argument

Create/reload failed on sda1

Device-mapper: reload ioctl on sda2failed: Invalid argument

Create/reload failed on sda2

BLKPG: Device or resource busy

Error adding partition 1

BLKPG: Device or resource busy

Error adding partition 2

BLKPG: Device or resource busy

Error adding partition 3 (indicates that it has been read to the disk)

C. Create a logical volume and mount it to a specific directory. Set the directory to/mydata.

[Root @ localhost ~] # Pvcreate/dev/sda3

Physical volume "/dev/sda3" successfully created

[Root @ localhost ~] # Vgcreate myvg/dev/sda3

Volume group "myvg" successfully created

[Root @ localhost ~] # Lvcreate-L 10G-nmydata myvg

Logical volume "mydata" created

[Root @ localhost ~] # Mke2fs-t ext4-LMYDATA-B 4096-m 3/dev/myvg/mydata

And can be mounted on the boot device. Edit the fastab file.

/Dev/mapper/vg0-root/ext4 ults 1 1

UUID = 90ebd4cf-95c1-4338-b0dd-19b2b1cb943d/boot ext4 ults 1 2

LABEL = MYDATA/mydata ext4 defaults 0 0

(BOOT mounting)

D. Create a user to run the process securely and create a link

[Root @ localhost ~] # Groupadd-r mysql

[Root @ localhost ~] # Useradd-g mysql-r mysql

[Root @ localhost ~] # Idmysql

Uid = 496 (mysql) gid = 493 (mysql) groups = 493 (mysql)

[Root @ localhost ~] # Chown-R mysql. mysql/mydata/data/

[Root @ localhost ~] # Ll-a/mydata/data/

Total 8

Drwxr-xr-x 2 mysql mysql4096 Aug 11 20:15.

First go to the/usr/local directory

[Root @ localhost local] # ln-sv mariadb-5.5.36-linux-x86_64 mysql

Lrwxrwxrwx1 root 27 Aug 11 20: 18 mysql-> mariadb-5.5.36-linux-x86_64

E. Provide the primary configuration file for mysql.

Cd/usr/local/mysql/

Mkdir/etc/mysql creates a directory, because there is a my. cnf under/etc

Cpsupport-files/my-large.cnf/etc/mysql/my. cnf

Vim/etc/mysql/my. cnf

Port = 3306

Socket =/tmp/mysql. sock

Query_cache_size = 16 M

# Try number of CPU's * 2 for thread_concurrency

Thread_concurrency = 8

Datadir =/mydata/data (specify the storage location of mysql data Files)

Start Initialization

[Root @ localhostmysql] # scripts/mysql_install_db -- user = mysql -- datadir =/mydata/data/

(This must be in the mysql directory. If you want to initialize it in scripts, an error will be reported)

F. Provide the sysv service script for mysql.

[Root @ localhostmysql] # cp support-files/mysql. server/etc/rc. d/init. d/mysqld

Then add it to the service list.

[Root @ localhost mysql] # chkconfig -- addmysqld

[Root @ localhost mysql] # chkconfig -- list mysqld

Mysqld 0: off1: off2: on3: on4: on5: on6: off

Start the service

Root @ localhost mysql] # service mysqld start

Starting MySQL... [OK]
