介绍
LNMP与LAMP
LNMP架构：linux + Nginx + Mysql + PHP 的结构体系
LAMP架构：linux + Apache + Mysql + PHP 的结构体系
很明显他们的区别在于Nginx和Apache
我们先了解一下nginx和apache的区别
| Nginx | Apache |
|---|---|
| 本身是代理服务器，负载均衡能力强，可实现分布式架构及高可用集群 | 动态页面处理能力强 |
| 占用内存资源少，可处理高并发请求 | rewrite 功能强大 |
| 模块设计编写相对简单 | 模块超多，基本想到的都可以找到 |
| 社区活跃，高性能模块出品快 | 稳定性强，bug少 |
之后我们再看看LNMP与LAMP的差异
-
LNMP
在LNMP架构中 php是一个独立程序，可以单独部署php集群 -
LAMP
在LAMP架构中 php是apache的一个插件，php和apache只能在一个节点上。
LNMP架构部署
安装
- 节点规划
| 主机 | IP | 角色 |
|---|---|---|
| php-server | 192.168.139.134 | php脚本程序解析 |
| nginx-server | 192.168.139.131 | web服务 |
| mysql-server | 192.168.139.135 | 数据库节点 |
nginx安装部署请看
nginx安装
软件版本
nginx version: nginx/1.14.0
mysql Ver 8.0.18
php 7.2.0
- 处理防火墙
systemctl stop firewalld
systemctl disable firewalld
setenforce 0 //临时处理selinux防火墙
- 修改主机名
hostnamectl set-hostname nginx-server
su - l
hostnamectl set-hostname php-server
su - l
hostnamectl set-hostname mysql-server
su - l
- 时间同步
yum install -y ntp ntpdate
ntpdate cn.pool.ntp.org
hwclock --systohc
三个节点做时间同步
-
mysql安装
– 下载rmp包安装
mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar
– 配置yum源
安装过程中可能会存在依赖，修改安装网络源来解除依赖。
安装阿里镜像源
阿里源– 卸载Mariadb
rpm -e mariadb-libs postfix– 安装mysql
groupadd mysql
useradd -g mysql mysql
mkdir mysql
tar xf mysql-8.0.18-1.el7.x86_64.rpm-bundle\ \(1\).tar -C mysql
cd mysql
yum localinstall mysql-community-client-8.0.18-1.el7.x86_64.rpm mysql-community-server-8.0.18-1.el7.x86_64.rpm mysql-community-libs-8.0.18-1.el7.x86_64.rpm mysql-community-common-8.0.18-1.el7.x86_64.rpm
启动
systemctl start mysqld
找到root默认密码
grep “temporary password” /var/log/mysqld.log
-
php 安装
安装目录 /usr/local/php
– 下载安装包
php-7.2.0.tar.gz
– 安装依赖包
[root@php-server ~]# yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
解压
tar zxvf php-7.2.0.tar.gz -C /usr/local/src/
cd /usr/local/src/php-7.2.0
编译
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php --enable-mbstring --with-openssl --enable-ftp --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-pear --enable-sockets --with-freetype-dir=/usr --with-zlib --with-libxml-dir=/usr --with-xmlrpc --enable-zip --enable-fpm --enable-xml --enable-sockets --with-gd --with-zlib --with-iconv --enable-zip --with-freetype-dir=/usr/lib/ --enable-soap --enable-pcntl --enable-cli --with-curl

echo "faling...";
else
echo "success connect mysql\n";
?>
注:
- 数据库创建的用户可以远程访问
- 需要给创建用户数据库的权限
- 创建用户时修改认证插件 mysql_native_password,并开放端口
在my.cnf 中 放开
default-authentication-plugin=mysql_native_password
