centos7搭建LNMP(wordpress)

一、思路：

1、使用脚本自动化安装。

2、分别安装mysql和nginx/php，可以根据需要安装在同一台机器或不同机器上。

二、实践：

1、安装mysql，并配置wordpress账号。为了方便测试，使用默认的配置。

#cat lamp-mysql.sh

#!/bin/bash

yum install -y mariadb-server
systemctl enable --now mariadb

#mysql_secure_installation

cat > create_sql_user.sql <<-EOF
create database wordpress;
grant all on wordpress.* to username@'%' identified by 'password';

flush privileges;
EOF

mysql < create_sql_user.sql

2、安装配置nginx\php。下载wordpress，解压、拷贝到nginx指定的网页部署目录（/data/nginx）。这里使用清华镜像源加速下载php。

#cat lnmp-web.sh

#!/bin/bash

# nginx+php

nginx_data="/data/nginx"

wget https://cn.wordpress.org/wordpress-5.9.3-zh_CN.tar.gz
wget https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm --no-check-certificate

yum install -y remi-release-7.rpm
sed -i '/^mirrorlist=/c\mirrorlist=https:\/\/mirrors.tuna.tsinghua.edu.cn\/remi\/enterprise\/7\/safe\/mirror' /etc/yum.repos.d/remi-safe.repo

yum install -y nginx php74-php php74-php-fpm php74-php-mbstring php74-php-mysqlnd  \
  php74-php-xml.x86_64 php74-php-opcache.x86_64 unzip tree 

mkdir ${nginx_data}/{html,blog,forum} -p
echo ${nginx_data}/html/index.html > ${nginx_data}/html/index.html

tar vxf wordpress-5.9.3-zh_CN.tar.gz
#rm -f wordpress-5.9.3-zh_CN.tar.gz
mv wordpress/* ${nginx_data}/blog

chown -R nginx.nginx ${nginx_data}

sed -i '/^http {/a\    server_tokens off;' /etc/nginx/nginx.conf

cat > /etc/nginx/conf.d/blog.conf <<-EOF
server{
  listen 80;
  server_name blog.17.com;
  location / {
    root /data/nginx/blog;
    index index.php index.html index.htm;
  }
  error_page 500 502 503 /50x.html;
  location = /50x.html {
    root html;
  }
  location ~ \.php$|pm_status|ping {
    root /data/nginx/blog;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME \$document_root\$fastcgi_script_name;
    include fastcgi_params;
  }
}
EOF

sed -i -e '/^user =/c user = nginx' -e '/^group =/c group = nginx' \
  -e '/^listen = /c listen = 127.0.0.1:9000' \
  -e '/^\;pm.status_path = /c pm.status_path = \/pm_status' \
  -e '/^\;ping.path =/c ping.path = \/ping' /etc/opt/remi/php74/php-fpm.d/www.conf

sed -i -e '/^upload_max_filesize = /c upload_max_filesize = 20M' \
       -e '/^post_max_size = /c post_max_size = 10M' \
       -e '/^expose_php =/c expose_php = Off'  /etc/opt/remi/php74/php.ini

systemctl enable --now nginx php74-php-fpm

3、用浏览器访问http:///blog ，网址不直接用wordpress，隐藏了产品信息。
