案例需求
通过shell脚本安装nginx
应用场景
web服务器业务初始化
案例思路
1、软件获得 2、源码安装
案例代码
代码语言：javascript复制#!/bin/bash
#Description: nginx install script from zutuanxue(http://www.zutuanxue.com)
#Release: 1.0
#Auther: www.zutuanxue.com
#Email:
#OS: Centos 8.X

#nginx源码包下载路径
nginx_pkg_url=http://nginx.org/download/nginx-1.17.8.tar.gz
#nginx安装路径,安装路径为$nginx_install_doc/nginx
nginx_install_doc=/usr/local
#nginx服务管理用户
nginx_manage_user=www
#统计本机CPU核数

check () {
#安装nginx需要管理员权限
[ $UID -ne 0 ] && echo "need to be root so that" && exit 1
#安装前的依赖包解决
#wget 命令
#gcc 编译命令
#pcre-devel URL重写功能
#zlib-devel 压缩支持
#make 编译命令
if ! (yum -y install wget gcc pcre-devel zlib-devel make &>/dev/null);then

nginx_install () {
#1、下载软件包
#if wget $nginx_pkg_url &>/dev/null;then
#2、解压软件包
echo $nginx_pkg_url|awk -F "/" '{print $5}'|xargs tar xf
nginx_source_doc=`echo $nginx_pkg_url|awk -F "/" '{print $5}'|cut -d "." -f 1-3`
#3、进入软件包
if [ ! -d $nginx_source_doc ];then
echo "unzip `echo $nginx_pkg_url|awk -F "/" '{print $5}'` fail"
exit 1
fi
cd $nginx_source_doc
#4、configure nginx
./configure --prefix=$nginx_install_doc/nginx --user=$nginx_manage_user --group=$nginx_manage_user 1>/dev/null
[ $? -ne 0 ]&&echo "nginx configure fail"&&exit 1
#5、make nginx
make -j $cpu_count 1>/dev/null
[ $? -ne 0 ]&&echo "nginx make fail"&&exit 1
#6、install nginx
make install 1>/dev/null
[ $? -ne 0 ]&&echo "nginx install fail"&&exit 1||echo "`clear`nginx install success..."
#7、delete nginx soft package
cd ..
rm -rf ${nginx_source_doc}*
#else
# echo "$nginx_pkg_url download fail"
# exit 1
#fi
}
#####callable function
check;nginx_install
