Shell 脚本攻略 | LNMP＋Zabbix 一建部署

准备环境

此脚本基于我之前写过一篇博客：基于 LNMP 部署 Zabbix 集中监控系统

---

脚本如下

#!/bin/bash

#----开局优化----
systemctl stop firewalld && systemctl disable firewalld
#关闭防火墙及开机自启

setenforce 0 && sed -i "s/SELINUX=*/SELINUX=disabled/g" /etc/selinux/config
#关闭安全访问控制机制及修改其配置配置文件避免开机自启

systemctl stop NetworkManager && systemctl disable NetworkManager
#关闭网络工具，在这里可能会和network产生冲突

#----配置在线YUM源仓库（aliyun）----
mkdir -p /etc/yum.repos.d
mv -f /etc/yum.repos.d/* /etc/yum.repos.d/repos-0.bak
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
#下载阿里云的镜像仓库至'/etc/yum.repos.d/目录下

yum clean all && yum makecache fast

#----开始搭建LNMP架构，作为搭建Zabbix的基础----

#--Nginx--

yum install -y nginx
systemctl start nginx.service && systemctl enable nginx.service

#--MySQL（MariaDB）--
yum -y install mariadb-server mariadb tcl expect
systemctl start mariadb.service && systemctl enable mariadb.service
