简单的一键部署LNMP架构shell脚本_centos

两种部署方式:

一、 手工搭建

分析:最终效果,通过Nginx搭建两个网站blog和zh,通过域名访问。在lnmp的基础上,域名访问,要么搭建DNS服务器,要么修改主机hosts文件。

1、安装Nginx:

进入yum目录配置网络源,Nginx官网、清华源均可,以清华源为例。

(2)复制wordpress安装包,到虚拟机/,解压并赋权

unzip wordpress-4.9.4-zh_CN.zip

chmod -R 777 /wordpress

简单的一键部署LNMP架构shell脚本_centos_08

(3)创建虚拟主机配置文件

vim /etc/nginx/conf.d/blog.conf
添加:
server {
listen 80;
server_name blog.benet.com;
root /wordpress;
index index.php index.html;

location ~ \.php$ {
root /wordpress;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
保存退出
systemctl reload nginx

(4)创建blog数据库和管理用户

登录数据库:mysql -uroot -p123.com

创建数据库:create database blog;

设置管理用户及密码:grant all on blog.* to lisi@localhost identified by ‘123.com’;

简单的一键部署LNMP架构shell脚本_centos_09

(5)客户端通过域名访问blog,安装并配置

安装DNS服务器:

yum -y install bind bind-chroot

编辑主配置:

备份默认主配置文件:

cd /etc/

mv named.conf named.conf.bak

创建配置文件:

vim named.conf

三、建立数据库连接出错

简单的一键部署LNMP架构shell脚本_nginx_19


1)使用mysql账号密码在另一台主机登录,排除myslq错误;

2)定位PHP的文件错误,查找wp-config.php文件,找不到,证明解压缺少配置文件。

删除Nginx及php的网页目录/wordpress/

重新解压拷贝,赋权,刷新,解决问题完成访问http://blog.benet.com

应用2:搭建知乎wecenter

(1)下载wecenter源码包

(2)复制wecenter安装包,到虚拟机/zh目录下,赋权,并复制/zh目录到php服务器

建议断开网络,否则会连接官网加载东西,耗费时间。

cd /zh //建议创建,根目录/zh,它解压完是没有主目录,零散的。

unzip Wecenter_3-3-4.zip

chmod -R 777 /zh

(3)创建虚拟主机配置文件
vim /etc/nginx/conf.d/zh.conf

添加:
server {
listen 80;
server_name zh.benet.com;
root /zh;
index index.php index.html;

location ~ \.php$ {
root /zh;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
保存退出
systemctl reload nginx

(4)创建blog数据库和管理用户

登录数据库:mysql -uroot -p123.com
创建数据库:create database zh;
设置管理用户及密码:grant all on zh.* to wangwu@localhost identified by '123.com';

(5)客户端通过域名访问zh,安装并配置

简单的一键部署LNMP架构shell脚本_php_22


执行下一步,报错:数据库连接失败!

简单的一键部署LNMP架构shell脚本_php_23

解决方案:用其他主机以创建的zh账号登录mysql,成功;排除mysql账户密码错误问题;

还是解压/zh,缺少文件,别问为什么?命令没错,解压再三丢失文件;删除web1的/zh目录,重新解压,并拷贝一份到php服务器,对比确实少一个文件。;

简单的一键部署LNMP架构shell脚本_运维_24


再次尝试,还是这个错误,发现问题:分布式安装,默认选项localhost,必须改成真实ip;解决问题。

报错:

简单的一键部署LNMP架构shell脚本_运维_25


解决方案:mysql数据库地址更改,只更改主配置文件,而wp-config.php不会自动更改,所以手动更改正确地址即可!

二、 脚本自动搭建(可以有好多种形式的脚本,给大家介绍一个相对复杂,但功能更完善的脚本)

分析:LNMP是这个架构的基础,保障能更好的运行,加入keepalived,实现高可用。比如:一台Nginx服务器故障,keepalived可以自动切换到另一台Nginx服务器,保障业务不中断;expect是实现免交互的一个服务,调用expect做免密登录,同时部署多台服务器,WordPress是一种使用PHP语言开发的博客平台,用户可以在支持PHP和MySQL数据库的服务器上架设属于自己的网站;当然,好比造一辆高端的车,比造一台普通的车,难度高,我的另一个教程没这两个服务,部署相对简单,需要可看​​玩转Linux系统之shell脚本轻松搭建LNMP平台架构​​ 脚本及注释如下图:
