第17周

1、部署分离的LAMP，部署到二台服务器上，php加载xcache模块

01主机安装php和httpd，02主机安装mysql（mariadb）

[root@centos01 ~]#yum install php php-mysql httpd -y
[root@centos02 ~]#yum install mariadb-server.x86_64 -y
上传wordpress压缩包到01主机

配置并启动mysql

[root@centos02 ~]#systemctl start mariadb.service 
[root@centos02 ~]#mysql

Your MariaDB connection id is 2

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

#01主机验证mysql远程连接
[root@centos01 ~]#mysql -uwordpress -p110110 -h192.168.7.72

MariaDB [(none)]> use  wordpress;

MariaDB [wordpress]> show tables;
Empty set (0.00 sec)

安装配置wordpress

[root@centos01 ~]#mkdir /data/wordpress
[root@centos01 ~]#tar xvf wordpress-5.0.2-zh_CN.tar.gz -C /data/wordpress
[root@centos01 ~]#cd /data/
[root@centos01 data]#setfacl -Rm u:apache:rwx wordpress 
[root@centos01 data]#mv wordpress/* /var/www/html/
[root@centos01 wordpress]#mv wp-config-simple.php wp-config.php
[root@centos01 wordpress]#vim wp-config.php                             #修改配置文件
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'wordpress');

/** MySQL数据库密码 */
define('DB_PASSWORD', '110110');

/** MySQL主机 */
define('DB_HOST', '192.168.7.72'); 
[root@centos01 ~]#systemctl start httpd.service

2、收集apache访问日志，并实现图形化展示

注：rsyslog与php也装在01机器上
mysql服务器上授权rsyslog能连接此数据库

[root@centos02 ~]#mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 4
Server version: 5.5.65-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> grant all on Syslog.* to loguser@'192.168.7.%' identified by '120120';
Query OK, 0 rows affected (0.00 sec)

rsyslog服务器上安装mysql模块相关的程序包

[root@centos01 ~]#yum install rsyslog-mysql.x86_64 -y
[root@centos01 ~]#rpm -ql rsyslog-mysql 
/usr/lib64/rsyslog/ommysql.so
/usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql

rsyslog上创建数据库和表

[root@centos01 ~]#mysql -uloguser -p120120 -h192.168.7.72 < /usr/share/doc/rsyslog-8.24.0/mysql-createDB.sql 
[root@centos01 ~]#mysql -uloguser -p120120 -h192.168.7.72

修改rsyslog配置文件

[root@centos01 ~]#vim /etc/rsyslog.conf
#### MODULES ####
$ModLoad ommysql
#### RULES ####
*.info;mail.none;authpriv.none;cron.none                :ommysql:192.168.7.72,Syslog,loguser,120120

安装loganalyzer

[root@centos01 ~]#yum install php-gd -y              #图形化显示插件
[root@centos01 ~]#tar xvf loganalyzer-4.1.7.tar.gz 
[root@centos01 ~]#cp -a loganalyzer-4.1.7/src/ /var/www/html/loganalyzer
[root@centos01 ~]#cd /var/www/html/loganalyzer
[root@centos01 loganalyzer]#touch config.php
[root@centos01 loganalyzer]#chmod 666 config.php 
[root@centos01 loganalyzer]#systemctl restart rsyslog.service 
[root@centos01 loganalyzer]#systemctl restart httpd.service
