Nginx启动脚本的编写
安装nginx:
使用yum搜索nginx的安装包
[root@localhost ~]# yum search nginx
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Name and summary matches only, use "search all" for everything.
#发现没有我们要的nginx包
所以我们就再官nginx.org上下载
前面我写过在官网上选择适合自己系统的软件包
相关技巧可以参考我写的《linux系统软件包常用发布网址和各种linux系统的介绍(自己积累)》这篇文章

./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.
编译报错排错过程
根据报错：
加上了参数 --without-http_gzip_module
