Shell 腳本攻略 | LNMP＋Zabbix 一建部署

準備環境

此腳本基于我之前寫過一篇博客：基于 LNMP 部署 Zabbix 集中監控系統

腳本如下

#!/bin/bash

#----開局優化----
systemctl stop firewalld && systemctl disable firewalld
#關閉防火墻及開機自啟

setenforce 0 && sed -i "s/SELINUX=*/SELINUX=disabled/g" /etc/selinux/config
#關閉安全訪問控制機制及修改其配置組態檔避免開機自啟

systemctl stop NetworkManager && systemctl disable NetworkManager
#關閉網路工具，在這里可能會和network產生沖突

#----配置在線YUM源倉庫（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
#下載阿里云的鏡像倉庫至'/etc/yum.repos.d/目錄下

yum clean all && yum makecache fast

#----開始搭建LNMP架構，作為搭建Zabbix的基礎----

#--Nginx--
echo '[nginx-stable]

baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0

yum clean all && yum makecache fast
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

/usr/bin/expect <<-EOF
spawn mysql_secure_installation
expect "(enter for none)" {send "\r"}
expect "Set root password" {send "y\r"}
