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

  1. #!/bin/bash
  2. #Description: nginx install script from zutuanxue(http://www.zutuanxue.com)
  3. #Release: 1.0
  4. #Auther: www.zutuanxue.com
  5. #Email: 
  6. #OS: Centos 8.X
  8. cat <<EOF
  9. #Description: nginx install script from zutuanxue(http://www.zutuanxue.com)
  10. #Release: 1.0
  11. #Auther: www.zutuanxue.com
  12. #Email: 
  13. #OS: Centos 8.X
  14. EOF
  17. #nginx源码包下载路径
  18. nginx_pkg_url=http://nginx.org/download/nginx-1.17.8.tar.gz
  20. #nginx安装路径,安装路径为$nginx_install_doc/nginx
  21. nginx_install_doc=/usr/local
  23. #nginx服务管理用户
  24. nginx_manage_user=www
  26. #统计本机CPU核数
  27. cpu_count=`grep -c "flags" /proc/cpuinfo`
  29. check ()  {
  31. #安装nginx需要管理员权限    
  32. [ $UID -ne 0 ] && echo "need to be root so that" && exit 1
  34. #安装前的依赖包解决
  35. #wget 命令
  36. #gcc  编译命令
  37. #pcre-devel  URL重写功能
  38. #zlib-devel  压缩支持
  39. #make  编译命令
  41. if ! (yum -y install wget gcc pcre-devel zlib-devel make &>/dev/null);then

  47.     useradd -s /sbin/nologin -r -M www
  48. fi
  50. }
  54. nginx_install () {
  55. #1、下载软件包
  56. #if wget $nginx_pkg_url &>/dev/null;then
  57.     #2、解压软件包

  64.         fi      
  66.     cd $nginx_source_doc
  68.     #4、configure nginx
  69.     ./configure --prefix=$nginx_install_doc/nginx --user=$nginx_manage_user --group=$nginx_manage_user 1>/dev/null
  70.     [ $? -ne 0 ]&&echo "nginx configure fail"&&exit 1
  72.     #5、make nginx

  74.     [ $? -ne 0 ]&&echo "nginx make fail"&&exit 1
  76.         #6、install nginx
