一、需求
公司需求安装Nginx，这里采用rpm包一键安装方式进行，本身rpm包安装也很快，这里还是使用脚本进行，省的折腾。
- 采用官方提供的rpm安装
- 优点：快速安装完毕，比较通用
- 缺点：无法定制化安装
- 源码编译
-
优点：可以定制化编译安装
-
缺点：安装慢，通用性不好(还需要自己写服务管理脚本)
-
二、脚本代码解析
# 同理通过rpm -ivh加载nginx官方源
# 通过yum进行安装nginx
# nginx官方文档：http://nginx.org/en/docs/
#CentOS 安装nginx
nginx_install() {
num=1
sys_ver=`lsb_release -r |awk -F' ' '{print2}'|awk -F'.' '{ print 1 }'`
if [ "`check_rpm nginx-release`" == "0" ]; then
rpm -ivh http://nginx.org/packages/centos/{sys_ver}/noarch/RPMS/nginx-release-centos-{sys_ver}-0.el{sys_ver}.ngx.noarch.rpm >/dev/null >&1
if [ "`check_rpm nginx-release`" != "0" ]; then
echo "\033[32mnginx源安装成功\033[0m"
else
echo "\033[31mnginx源安装失败\033[0m"
fi
else
echo "\033[31m已存在nginx源\033[0m"
fi
if [ `check_rpm nginx-1` == 0 ]; then
yum install -y nginx ImageMagick >/dev/null >&1
