源碼安裝構建網站架構

很久沒寫些博客了 剛剛找到工做，工做沒幾天就有幸參與了公司網站的拆分項目 今天就寫這些東西 主要是用來熟悉下源碼安裝的過程 方便本身的記憶

項目名稱：數據庫以及應用的拆分

項目需求：因爲網站的後臺數據庫的日益增加形成數據庫過大 數據庫的查詢過程過慢 影響到公司的業務 基於索引的數據庫優化已經起不到什麼效果 基於這種現狀 提出採用數據拆分 把網站中數據庫與前端和後臺平均拆分紅5個子端 平均每一個子端有4臺服務器服務器操做系統採用lnmp架構 由於相比IIS lnmp架構能更穩定更高效的支持網站訪問 支持高流量和高併發 此架構能保證公司業務的穩定性以及方便後續業務的擴展 由於此架構可能會出現單點故障 沒有冗餘措施 建議項目後續實現服務器的高可用 以及實現分佈式監控項目對服務器及服務狀態實現實時監控

項目功能：本項目數據庫採用mysql 後臺採用nginx+php+phpmyadmin實現後臺管理 nginx在前端實現靜態頁面的請求迴應和動態頁面請求的轉發 後端php+nginx負責處理動態頁面的請求

版本號：nginx-1.1.5.tar.gz mysql-5.1.37.tar.gz php-5.5.3.tar.gz notice: 全部四臺機器所有關閉防火牆（selinux）

本配置文檔按照第一臺爲數據庫 安裝軟件爲Mysql 第二臺爲後臺管理 安裝軟件爲phpmyadmin+php+nginx 第三臺爲nginx 第四臺爲nginx+php

第一臺主要功能爲提供數據庫支持 只需安裝數據庫就好 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

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

第二臺機器須要提供後臺管理數據庫功能 須要注意的是php在編譯時須要提供mysqli模塊的支持還要啓用php-fpm的支持 因爲php5.3以上已經提供Mysqli模塊的支持 支持mysql native driver 只要yum安裝mysql-devel就能夠 配置以下

php部分

groupadd nginx

useradd nginx -g nginx
