LNMP simple deployment architecture introduces articles
Introduce a .LNMP
1 the distal end and back-end web services series storage services
2. The main process to achieve dynamic request php
working principle:
L:linux N：nginx M：mysql P：php
Two, lnmp deployment
My environment: centos6.9 + nginx + mysql5.6 + php5 NFS file storage system
1. Installation linux deployment system (not presented here)
To complete the basic optimization operation (turn off the firewall, turn off selinuxn the / tmp directory permissions set to 1777)
2. Deploy nginx service
Here ignore ...................
3. Install the deployment mysql
Three methods of installation: yum deploy, compile and install the source code, binary package installation
This method describes the binary installation:
The first mileage: Download and extract the installation package mysql
mysql official download link address: ftp://ftp.jaist.ac.jp/pub/mysql/Downloads/MySQL-5.6/
Upload mysql software program, carried out using the software to upload xftp
tar xf mysql-5.6.34-linux-glibc2.5-x86_64.tar.gz
mv mysql-5.6.34-linux-glibc2.5-x86_64 /application/mysql-5.6.34 (my installation directory / application / mysql you pick)
Second mileage: Create a soft link program
ln -sf /application/mysql-5.6.34/ /application/mysql
Third mileage: Create a database user management and authorization to data directory
useradd -s mysql /sbin/nologin -M
chown -R mysql.mysql /application/mysql/data/
Fourth mileage: initialize the database service
/application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql
Fifth mileage: Start mysql service
/application/mysql/support-files/mysql.server /etc/init.d/ CP mysqld Sed -ri ' S # / usr / local # / file application # G ' /etc/init.d/mysqld / file application / MySQL / bin / mysqld_safe (the default path into your own installation directory) cp /application/mysql/support-files/my-default.cnf / etc / my.cnf /etc/init.d/mysqld Start
The sixth mileage: Set the root user password database
/ Application / mysql / bin / mysqladmin -uroot password "password =="
/ Application / mysql / bin / mysql -uroot -poldboy123 (too hard to knock up their own soft link)
4. PHP installation and deployment
The first mileage: dependency resolution PHP software
-y install zlib-devel yum libxml2-devel-Turbo libjpeg libjpeg-devel-devel libiconv FreeType-devel libpng-devel-devel gd-devel libcurl-devel libxslt- devel libiconv software installation --- character set conversion library (default may not installing a) cd / Server / Tools # wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz tar zxf libiconv -1.14.tar. GZ cd libiconv -1.14 ./configure = --prefix / usr / local / libiconv the make && the make install If yum installed, note yum update source at # wget -O /etc/yum.repos.d/epel.repo HTTP: //mirrors.aliyun.com/repo/epel-6.repo yum -y install libmcrypt-devel mhash mcrypt rpm -qa libmcrypt-devel mhash mcrypt
Second mileage: PHP unzip software download
php官方网站下载：php.net cd /server/tools/ tar xf php-5.5.32.tar.gz cd php-5.5.32 ./configure \ --prefix=/application/php-5.5.32 \ --with-mysql=/application/mysql-5.6.34 \ --with-pdo-mysql=mysqlnd \ --with-iconv-dir=/usr/local/libiconv \ --with-freetype-dir \ --with-jpeg-dir \ --with-png-dir \ --with-zlib \ --with-libxml-dir=/usr \ --enable-xml \ --disable-rpath \ --enable-bcmath \ --enable-shmop \ --enable-sysvsem \ --enable-inline-optimization \ --with-curl \ --enable-mbregex \ --enable-fpm \ --enable-mbstring \ --with-mcrypt \ --with-gd \ --enable-gd-native-ttf \ --with-openssl \ --with-mhash \ --enable-pcntl \ --enable-sockets \ --with-xmlrpc \ --enable-soap \ --enable-short-tags \ --enable-static \ --with-xsl \ --with-fpm-user=www \ --with-fpm-group=www \ --enable-ftp \ --enable-opcache=no ##为了防错(配置下以下信息) ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/ touch ext/phar/phar.phar #编译安装 make && make install ln -s /application/php-5.5.32/ /application/php
Third mileage: Setting PHP configuration file
php.ini php-fpm.ini cp php.ini-production /application/php-5.5.32/lib/ cd /application/php/etc/ cp php-fpm.conf.default php-fpm.con
Fourth mileage: Start php Service
/application/php/sbin/php-fpm
netstat -lntup|grep php
5.php software in conjunction with mysql and nginx
5.1, and binding mysql
Write .php file
? < PHP // $ link_id = mysql_connect ( 'hostname', 'user', 'password'); // MySQL password -h host -u user -p $ link_id = mysql_connect ( 'localhost', 'root', ' oldboy123 ') or mysql_error (); IF ( $ link_id ) { echo "MySQL successful by Oldboy \ n-!" ; } the else { echo mysql_error (); } >?
5.2, php combined with nginx
Nginx configuration file written nginx.conf
nginx and php combine: preparation of nginx configuration file LOCATION LOCATION .. ~ * * \ (php | php5) $ {? fastcgi_pass 127.0.0.1:9000 ; #php service default port 9000 fastcgi_index index.php; the include fastcgi.conf; }
6, the deployment of a website
The first mileage: download and upload website code
Second mileage: decompression program code, the program will save the code to the site directory and nginx authorization
E.g:
tar xf wordpress-4.7.3-zh_CN.tar.gz mv wordpress/* /application/nginx/html/blog/ chown -R www.www /application/nginx/html/blog/
Third mileage: direct access to the website, initialize operation
Create a database:
create database
Create a user connection data information
grant all on wordpress.* to '用户名'@'localhost' identified by '密码'; select user,host from mysql.user;
7. LNMP architecture, data migration
In the production environment, we finally need to migrate data to back-end storage server, the separation of static and dynamic resources
Here a brief Ha! ! !
01. LNMP database schema migration services
Migrating database: use the database backup command (mysql mysqladmin mysqldump)
1) backup database database information
For example: the mysqldump -uroot--p-Databases password --all> / tmp / bak.sql LL /tmp/bak.sql - H SCP /tmp/bak.sql 172.16 . 1.51 : / tmp / # pushed to a remote database server
2) restore the database information database
-poldboy123-uroot-MySQL </ tmp / bak.sql ### DB01 add a new user Grant All ON WordPress. * to username @ ' 172.16.1.0/255.255.255.0 ' IDENTIFIED by ' password ' ; flush privileges; MySQL - -poldboy123 -h uwordpress 172.16 . 1.51
3) database migration is complete, modify the configuration file of the site database connection
I am here for the php program to connect the database configuration file
MySQL -u user name -p password -h 172.16.1.51 <- before modifying the configuration file, test the database connectivity web site after the server migration vim WP <-config.php - database connection parameters on the modification information wordpress / * * the MySQL host * / DEFINE ( 'DB_HOST', '172.16.1.51') <- modify connection host information, to modify the localhost 172.16.1.51 Description: web server database can now be closed
4) Stop the MySQL server nginx service
/etc/init.d/mysql stop
02. LNMP data architecture migration to NFS storage instructions
01: first data out of the original directory
cd / the Application / nginx / HTML / Blog / WP-Content / uploads # file path resources at my site directory mkdir / tmp / wordpress_backup - the p- mv . / * / tmp / wordpress_backup /
note:
What location data stored locally, acquisition method
①. Web page by right-clicking, access to resources address information
②. Find command using the 5 -mmin
③. Using the directory data service monitoring changes inotify
02: configuration creates a shared directory on the NFS server
Vim / etc / Exports / Data 172.16.1.0/24(rw,sync, the all_squash) the showmount -e 172.16.1.31 Mount -t 172.16.1.31:/data NFS / mnt / # on the web server the showmount -e 172.16.1.31 Mount nfs 172.16.1.31:/data/ ./uploads/ -t # the nfs shared directory on the server to mount local mv / tmp / wordpress_backup / * ./ # restore the backup of the data before
