1豆混、部署分離的LAMP甲馋，部署到二臺服務(wù)器上，php加載xcache模塊
兩臺主機 172.16.100.46 172.16.100.47
在172.16.100.46上安裝
apache+php

[root@localhost ~]# yum -y install php httpd php-mysql
[root@localhost wordpress]# setfacl  -Ru:apache:rwx /var/www/html/wordpress

在172.16.100.47

[root@localhost ~]# yum install mariadb-server -y
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql

安裝加載xcache模塊適用于PHP5

https://github.com/lighttpd/xcache/archive/3.2.0.tar.gz 下載源碼包
yum -y install php-devel  gcc   配置編譯環(huán)境
tar xf xcache-3.2.0.tar.gz   
[root@localhost xcache-3.2.0]# phpize --clean && phpize   生成編譯腳本
[root@localhost xcache-3.2.0]# ./configure --enable-xcache
[root@localhost xcache-3.2.0]# make && make install
[root@localhost xcache-3.2.0]# cp xcache.ini /etc/php.d/
[root@localhost xcache-3.2.0]# systemctl restart httpd.service

2眼耀、部署wordpress論壇蚯舱，并實現(xiàn)正常訪問登錄論壇改化。

兩臺主機 172.16.100.46 172.16.100.47
在172.16.100.46上安裝
apache+php

[root@localhost ~]# yum -y install php httpd php-mysql
wordpress下載 https://cn.wordpress.org/download/releases/
[root@localhost data]# tar xvf wordpress-5.0.3-zh_CN.tar.gz 
[root@localhost wordpress]# setfacl  -Ru:apache:rwx /var/www/html/wordpress
收回權(quán)限：
 [root@localhost wordpress]# setfacl -b /var/www/html/wordpress

在172.16.100.47

[root@localhost ~]# yum install mariadb-server -y
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql

3、收集apache訪問日志枉昏，并實現(xiàn)圖形化展示陈肛。
3臺測試機

rsyslog服務(wù)器上安裝mysql模塊相關(guān)的程序包

[root@localhost ~]#yum install rsyslog-mysql.x86_64 -y
[root@localhost ~]# rpm -ql rsyslog-mysql
/usr/lib64/rsyslog/ommysql.so
/usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql
[root@localhost ~]# scp /usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql 172.16.100.47:/data

創(chuàng)建數(shù)據(jù)庫和表

[root@localhost ~]# mysql < /data/mysql-createDB.sql 
[root@localhost ~]# mysql

MariaDB [(none)]> grant all on Syslog.* to loguser@'172.16.100.%' identified by 'centos';
Query OK, 0 rows affected (0.00 sec)

更改rsyslog.conf 配置文件

[root@localhost ~]#vim /etc/rsyslog.conf 
$ModLoad ommysql
*.info;mail.none;authpriv.none;cron.none                :ommysql:172.16.100.47,Syslog,loguser,centos
[root@localhost ~]#systemctl restart rsyslog

搭建lap

yum install httpd php php-mysql php-gd
安裝loganalyzer
[root@localhost logs]# tar xvf loganalyzer-4.1.7.tar.gz
[root@localhost loganalyzer-4.1.7]# ls
ChangeLog  contrib  COPYING  doc  INSTALL  src
[root@localhost loganalyzer-4.1.7]# mv src /var/www/html/logs
[root@localhost loganalyzer-4.1.7]# cd /var/www/html/logs
[root@localhost logs]# touch config.php
[root@localhost logs]# chmod 666 config.php
[root@localhost logs]# systemctl start httpd
