Linux基础及总结17之LAMP

1、部署分离的LAMP，部署到二台服务器上，php加载xcache模块

192.168.2.241  httpd+php-fpm
192.168.2.240  mysql
1）安装httpd和php
      yum -y install httpd php php-mysql php-fpm
2）修改httpd配置文件
      vim /etc/httpd/conf/httpd.conf
      DirectoryIndex index.php index.html #httpd默认首页添加php
      #添加如下几行，用于httpd支持php和proxy代理
      AddType application/x-httpd-php .php
      AddType application/x-httpd-php-source .phps
      ProxyRequests Off
      ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1
      查看是否httpd是否启用了proxy和fcgi模块，如果为启用编辑proxy配置文件启用模块
      vim /etc/httpd/conf.modules.d/00-proxy.conf
      LoadModule proxy_module modules/mod_proxy.so
  LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
        ![image.png](https://upload-images.jianshu.io/upload_images/10958113-29a3a78582255f17.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)
3）启动httpd和php-fpm服务
      systemctl  start  httpd php-fpm

4）在2.240机器上安装数据库，并创建授权登录账号
      yum -y install mariadb-server
      grant all on *.* to 'test'@'192.168.2.%' identified by 'test';
      flush privileges;
5）安装xcache模块，重启httpd、php-fpm服务
      yum -y install php-xcache
      systemctl restart httpd php-fpm  
6）对比测试结果
      ab -c1000 -n1000 http://192.168.2.241/index.php
      加载xcache前

      加载xcache后

2、部署wordpress论坛，并实现正常访问登录论坛。

  192.168.2.240    mysql  
  192.168.2.241    httpd+php

1）下所需的所有的软件包
wget http://mirror.bit.edu.cn/apache//httpd/httpd-2.4.41.tar.gz
wget https://www.php.net/distributions/php-7.4.3.tar.xz
wget http://mirror.bit.edu.cn/apache//apr/apr-1.7.0.tar.gz
wget http://mirror.bit.edu.cn/apache//apr/apr-util-1.6.1.tar.gz
wget https://github.com/WordPress/WordPress/archive/5.3.2.tar.gz
2）源码编译安装httpd
解压软件
tar xf httpd-2.4.41.tar.gz
tar xf apr-1.7.0.tar.gz -C httpd-2.4.41/srclib/
tar xf apr-util-1.6.1.tar.gz -C httpd-2.4.41/srclib/
安装依赖包
yum install gcc pcre-devel openssl-devel expat-devel oniguruma-devel
创建httpd运行用户
useradd -r -M -s /sbin/nologin apache
执行编译并安装
./configure --prefix=/app/httpd24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --enable-modules=most --enable-mpms-shared=all --with-mpm=prefork --with-included-apr
make -j 4 && make install

    修改httpd配置文件
    vim /app/http24/conf/httpd.conf
    取消如下两行注释，启用httpd proxy代理
    LoadModule proxy_module modules/mod_proxy.so
    LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
    修改httpd运行的用户和组为apache
    User apache
    Group apache
    DirectoryIndex行增加index.php
    
        DirectoryIndex index.php index.html
    
    添加如下四行，通过httpd请求php程序代理到php程序处理
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
    ProxyRequests Off
    ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/app/httpd24/htdocs/$1
    重启httpd服务
    apachectl restart

3）源码编译安装php
解压php源码包 tar xf php-7.3.15.tar.xz
安装编译所需依赖包
yum -y install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses curl gdbm-devel db4-devel libXpm-devel libX11-devel gd-devel gmp-devel expat-devel xmlrpc-c xmlrpc-c-devel libicu-devel libmcrypt-devel libmemcached-devel libzip gcc-c++
执行编译并安装
./configure --prefix=/app/php --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-openssl --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --enable-mbstring --enable-xml --enable-sockets --enable-fpm --enable-maintainer-zts --disable-fileinfo
make && make install
复制配置文件及php-fpm启动脚本，并且添加执行权限设置为开机启动
cp php.ini-production /etc/php.ini
 cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
 chmod +x /etc/init.d/php-fpm
 chkconfig --add php-fpm
 chkconfig php-fpm on

cd /app/php/etc
 cp php-fpm.conf.default php-fpm.conf
 cp php-fpm.d/www.conf.default php-fpm.d/www.conf
4）启动服务，查看程序运行状态
systemctl start php-fpm

创建php页面，验证httpd解析php
vim /etc/httpd24/htdocs/index.php
phpinfo();
?>

5）部署Wordpress
登录数据创建wordpress库和授权账户
create database wordpress;
grant all on wordpress.* to 'wordpress'@'192.168.2.%' identified by 'wordpress';
flush privileges;

  将WordPress程序解压到httpd网站根目录，重名了为wordpress，设置acl权限为apache账户具有读写执行的权限
  tar xf 5.3.2.tar.gz -C /app/httpd24/htdocs/
  cd /app/httpd/htdocs
   mv WordPress-5.3.2/ wordpress
  setfacl -Rm u:apache:rwx wordpress/
  浏览器访问wordpress进入安装向导，执行安装步骤

3、收集apache访问日志，并实现图形化展示。

    10.0.30.121  httpd+php
     10.0.30.122  mysql
1）安装httpd、php
      yum -y install httpd php php-mysql php-gd  rsyslog-mysql 
2）安装mysql添加授权账号
      yum -y install mariadb-server 
      grant all on Syslog.* to 'loguser'@'10.0.30.%' identified by 'loguser';

3）将创建存储rsyslog的库及表的sql语句，复制到mysql数据库节点并执行。
      scp /usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql 10.0.30.122:/root
4）修改httpd日志配置
       vim /etc/httpd/conf/httpd.conf
       将CustomLog "logs/access_log" combined日志项修改为
       CustomLog "|/usr/bin/logger -p local5.info" combined
5）修改rsyslog的配置
      vim /etc/rsyslog.conf
      $ModLoad imtcp     #启用tcp协议
      $InputTCPServerRun 514
      $ModLoad ommysql    #加载mysql模块支持
      *.*                 :ommysql:10.0.30.122,Syslog,log,log  #配置日志保存至mysql数据库
      local5.*                                                /var/log/httpd/access_log
      local6.*                                                /var/log/httpd/error_log
      重启httpd、rsyslog服务
      systemctl   restart   httpd  rsyslog
 6）下载并安装loganalyzer日志展示包
        wget http://download.adiscon.com/loganalyzer/loganalyzer-4.1.10.tar.gz
        将loganalyzer解压到httpd网站根目录
        tar -xf  loganalyzer-4.1.10.tar.gz -C  /var/www/html/
       cd  /var/www/html/ 
       cp -a loganalyzer-4.1.10/src  ./loganalyzer
        创建配置文件，并修改权限，为保障系统安全loganalyzer安装步骤执行完成后将config.php权限设置为644
        touch  ./loganalyzer/config.php
        chmod 666  ./loganalyzer/config.php
  7）通过浏览器访问并进行安装
        http://10.0.30.121/loganalyzer
