标签：脚本 doc echo nginx exit install fi 安装

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

[root@CentOs shell]# cat nginx_install.sh

#!/bin/bash

#安装用户   root
#安装前准备依赖包源码包获得
#安装
#启动测试

#variables(变量)

nginx_pkg="nginx-1.20.2.tar.gz"
nginx_source_doc=`echo $nginx_pkg|cut -d "." -f1-3`
nginx_install_doc="/usr/local/nginx"
nginx_user="www"
nginx_group="www"

#function
check(){

     #检测当前用户要求为root
     if [ "$USER" != 'root' ];then
   echo "Need to be root so that"
   exit 1
     fi

    #检查wget命令

    #    if [ ! -x /usr/bin/wget ];then
    #       echo "not fount command /usr/bin/wget"
    #     exit 1
    #     fi
    # "&&" == then "||" == else

            [ ! -x /usr/bin/wget ]&& echo "not fount command /usr/bin/wget" && exit 1

}

install_pre(){

         #1、安装依赖
               #1 :stdout(标准输入)
               #2：stderr(错误输出)
      if ! ( yum -y install gcc-* pcre-devel zlib-devel elinks 1>/dev/null);then
   echo "ERROR:yum install error"
   exit 1
      fi

         #2、下载源码包
      if wget http://nginx.org/download/$nginx_pkg &>/dev/null;then
   tar -zxvf $nginx_pkg
   if [ ! -d $nginx_source_doc ];then
       echo "ERROR:not found $nginx_source_doc"
       exit 1
   fi
      else
       echo "ERROR:download file $nginx_pkg fail"
       exit 1
      fi
}

install(){
      # 1、创建管理用户
   useradd -r -s /sbin/nologin www

      # 2、安装nginx源码
      cd $nginx_source_doc
      echo "nginx configure..."
      if ./configure --prefix=$nginx_install_doc --user=$nginx_user --group=$nginx_group 1>/dev/null;then
   echo "nginx make..."
   if make 1>/dev/null;then
        echo "nginx make install..."
         if make install 1>/dev/null;then
            echo "nginx install success!"
         else
       echo "nginx install fail"
       exit 1
         fi
   else
        echo "ERROR:nginx make fail"
        exit 1
        fi
      else
   echo "ERROR:nginx configure fail"
   exit 1
      fi
}

nginx_test () {

     if $nginx_install_doc/sbin/nginx;then
   echo "nginx start success!"
   elinks http://localhost -dump
     else
   echo "nginx stop fail!"
     fi

}

# callable(调用)

echo "this is nginx install script!"
read -p "press Y install,press C cancel：" ch（如果机器自动化安装脚本，这个交互我们就没有必要写了！）
if [ $ch == 'Y' ];then
   check;install_pre;install;nginx_test
elif [ $ch == 'C' ];then
   exit 1
fi

[root@CentOs shell]#
