源码安装构建网站架构

很久没写些博客了 刚刚找到工做，工做没几天就有幸参与了公司网站的拆分项目 今天就写这些东西 主要是用来熟悉下源码安装的过程 方便本身的记忆

项目名称：数据库以及应用的拆分

项目需求：因为网站的后台数据库的日益增加形成数据库过大 数据库的查询过程过慢 影响到公司的业务 基于索引的数据库优化已经起不到什么效果 基于这种现状 提出采用数据拆分 把网站中数据库与前端和后台平均拆分红5个子端 平均每一个子端有4台服务器服务器操做系统采用lnmp架构 由于相比IIS lnmp架构能更稳定更高效的支持网站访问 支持高流量和高并发 此架构能保证公司业务的稳定性以及方便后续业务的扩展 由于此架构可能会出现单点故障 没有冗余措施 建议项目后续实现服务器的高可用 以及实现分布式监控项目对服务器及服务状态实现实时监控

项目功能：本项目数据库采用mysql 后台采用nginx+php+phpmyadmin实现后台管理 nginx在前端实现静态页面的请求回应和动态页面请求的转发 后端php+nginx负责处理动态页面的请求

版本号：nginx-1.1.5.tar.gz mysql-5.1.37.tar.gz php-5.5.3.tar.gz notice: 全部四台机器所有关闭防火墙（selinux）

本配置文档按照第一台为数据库 安装软件为Mysql 第二台为后台管理 安装软件为phpmyadmin+php+nginx 第三台为nginx 第四台为nginx+php

第一台主要功能为提供数据库支持 只需安装数据库就好 配置以下

cd /usr/src

tar fzxv mysql-5.1.37.tar.gz

cd mysql-5.1.37

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel ssse2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers ncurses-devel

./configure --prefix=/usr/local/mysql --localstatedir=/var/lib/mysql --with-comment=Source --with-server-suffix=-Community --with-mysqld-user=mysql --without-debug --with-big-tables --with-charset=utf8 --with-collation=utf8_general_ci --with-extra-charsets=all --with-pthread --enable-static --enable-thread-safe-client --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --enable-assembler --without-ndb-debug --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock

make && make install

groupadd mysql

useradd -M mysql -s /sbin/nologin -g mysql

cp support-files/my-huge.cnf /etc/my.cnf

/usr/local/mysql/bin/mysql_install_db --user=mysql

chown -R root.mysql /usr/local/mysql/

echo "/usr/local/mysql/lib/mysql/" >> /etc/ld.so.conf

ldconfig

/usr/local/mysql/bin/mysqld_safe --user=mysql &

netstat -anpt | grep 3306

cp support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig mysqld on

service mysqld restart

export PATH=$PATH:/usr/local/mysql/bin/

echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

service mysqld restart

mysql

>use mysql

>update user set password=PASSWORD("abc-123")where user="root";

> flush privileges;

> quit

service mysqld restart

mysql -uroot -pabc-123

第二台机器须要提供后台管理数据库功能 须要注意的是php在编译时须要提供mysqli模块的支持还要启用php-fpm的支持 因为php5.3以上已经提供Mysqli模块的支持 支持mysql native driver 只要yum安装mysql-devel就能够 配置以下

php部分

groupadd nginx

useradd nginx -g nginx

cd /usr/src

tar fzxv php-5.5.3.tar.gz

cd php-5.5.3

fastcgi---配置

cd /usr/local/php5/etc/

cp php-fpm.conf.default php-fpm.conf

vi php-fpm.conf

user = nginx

group = nginx

(nginx/html目录下将具体虚拟目录的属主属组也改为nginx与nginx,保证PHP程序代码对该目录有读写权限.)

/usr/local/php5/sbin/php-fpm 启动

重启fpm:

# pkill php-fpm
