CentOS 7.7搭建LNMP环境部署WordPress，并使用Matomo监控

wordpress是一款使用PHP语言开发的博客平台，官网https://cn.wordpress.org/

matomo的前身是Piwik，一套基于PHP + MysqL技术构建的开源网站访问统计系统，matomo可以提供统计网页浏览人数、访问最多的页面、搜索引擎关键词等流量分析功能，它还采用了插件扩展及开放API架构，可以让用户根据自已的实际需求创建更多的功能，软件包下载和部署文档地址https://matomo.org/docs/installation/

一、安装配置Nginx：

1、安装epel源：# rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/epel/epel-release-latest-7.noarch.rpm

2、安装Nginx：# yum -y install Nginx

3、启动Nginx：

# systemctl start Nginx

# systemctl status Nginx

# ss -tunlp | grep -w :80

# systemctl enable Nginx

4、浏览器访问：http://192.168.0.122

二、安装配置MariaDB：

CentOS 7.7默认yum源中的MariaDB版本为5.5.64，此处安装MariaDB 10.4版本

1、查看系统中是否已经存在MariaDB，有则删除：

# rpm -qa | grep -i mariadb --> mariadb-libs-5.5.64-1.el7.x86_64

# yum -y remove mariadb-libs

2、配置MariaDB的yum源：

# vim /etc/yum.repos.d/MariaDB.repo

[mariadb]

name=MariaDB Repo

baseurl=http://mirrors.ustc.edu.cn/mariadb/yum/10.4/centos7-amd64/

gpgkey=http://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB

enabled=1

gpgcheck=1

3、安装MariaDB：# yum -y install MariaDB-server

4、修改配置文件server.cnf：

# cd /etc/my.cnf.d

# mv server.cnf server.cnf.bak

# vim server.cnf

[MysqLd]

port=3306

socket=/var/lib/MysqL/MysqL .sock

datadir=/var/lib/MysqL

log-error=/var/log/mariadb.log

lower_case_table_names=1

character-set-server=utf8mb4

collation-server=utf8mb4_general_ci

symbolic-links=0

innodb_file_per_table=1

skip_name_resolve=1

slow_query_log=1

slow_query_log_file=MysqL-slow.log

server_id=1

sync_binlog=1

innodb_flush_log_at_trx_commit=1

log_bin=MysqL-bin

log_bin_index=MysqL-bin.index

binlog_format=row

备注：默认主配置文件不是/etc/my.cnf，而是/etc/my.cnf.d/server.cnf

5、创建错误日志文件：

# touch /var/log/mariadb.log

# chown MysqL.MysqL /var/log/mariadb.log

6、启动MariaDB：

# systemctl start mariadb.service

# systemctl status mariadb.service

# ss -tunlp | grep -w :3306

# tail -100 /var/log/mariadb.log

# tail -100 /var/log/messages

# systemctl enable mariadb.service

7、MariaDB安全配置向导：# MysqL_secure_installation

8、授权用户远程登录：

# MysqL -uroot -p

MariaDB [(none)]> grant all on *.* to 'root'@'192.168.0.%' identified by '123456';

MariaDB [(none)]> flush privileges;

9、创建wordpress和matomo 数据库：

MariaDB [(none)]> create database wordpress;

MariaDB [(none)]> create database matomo;

10、创建新用户，并对其赋予数据库权限：

MariaDB [(none)]> create user 'wpuser'@'192.168.0.%' identified by '123456';

MariaDB [(none)]> grant all on wordpress.* to 'wpuser'@'192.168.0.%';

MariaDB [(none)]> create user 'mtuser'@'192.168.0.%' identified by '123456';

MariaDB [(none)]> grant all on matomo.* to 'mtuser'@'192.168.0.%';

MariaDB [(none)]> flush privileges;

三、安装配置PHP：

1、安装PHP：

# rpm -ivh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

# yum -y install mod_PHP72w PHP72w-cli PHP72w-common PHP72w-devel PHP72w-fpm PHP72w-gd PHP72w-ldap PHP72w-mbstring PHP72w-MysqLnd PHP72w-opcache PHP72w-xml

# PHP -version

2、修改www.conf配置文件：

# vim /etc/PHP-fpm.d/www.conf

user = apache --> user = Nginx

group = apache --> group = Nginx

3、启动PHP-fpm：

# systemctl start PHP-fpm.service

# systemctl status PHP-fpm.service

# ss -tunlp | grep 9000

# systemctl enable PHP-fpm.service

四、Nginx整合PHP：

1、修改 Nginx.conf配置文件：

# vim /etc/Nginx/Nginx.conf

location / {

root html;

index index.PHP index.html index.htm;

}

location ~ \.PHP$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.PHP;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

# Nginx -t

# Nginx -s reload

2、创建测试页：

# vim /usr/share/Nginx/html/index.PHP

<?PHP

$conn=MysqLi_connect("192.168.0.122","root","123456");

if ($conn)

echo "MysqLi_connect success";

else

echo "MysqLi_connect failure";

MysqLi_close();

PHPinfo();

备注：如果在新版本PHP中使用旧版本PHP的MysqL_connect()函数连接MysqL，会提示“undefined function MysqL_connect()”。从PHP 5.5版本开始，MysqL就不推荐使用MysqL_connect()函数，属于废弃函数，PHP 7中已经彻底不支持，增加了MysqLi_connect()函数。从某种意义上说，MysqLi是MysqL系统函数的增强版，更稳定、更高效、更安全，属于面向对象，用对象的方式操作驱动MysqL数据库。
