定制rpm包
# 什么是定制rpm包
将原本，使用源码安装的服务，打包成rpm包
安装fpm
# 1.下载阿里云的base源和epel源
wget-O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget-O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
# 2.安装ruby环境
yum -y install ruby rubygems ruby-devel
# 3.查看默认源
gem sources
# 4.移除默认源
gem sources --remove https://rubygems.org/
# 5.添加新源
gem sources -a https://mirrors.aliyun.com/rubygems/
# 6.安装fpm
gem install fpm -v 1.3.3
gem install *.gem
'uccessfully installed fpm-1.3.3 (显示这个代表安装正确)
8 gems installed (安装到8次即可，一直安装就行)
使用rpm定制rpm包
# 命令
fpm:
# 选项
-s:值将什么打成rpm包
-t:打成是包
-n:指定包名
-v:指定版本号
-d:指定依赖包
--post-install:安装rpm包之后，要执行的脚本
--pre-install:安装rpm包之前，要执行的脚本
--post-uninstall:卸载rpm包之后，要执行的脚本
--pre-uninstall:卸载rpm之前，要执行的脚本
-f:指定要打包的路径
# 先编写Nginx的rpm安装之后要执行的脚本
[root@66technicians ~]# vim post_Nginx.sh
(脚本内容)
ln -s /opt/Nginx-1.20.2 /opt/Nginx
echo 'PATH="/opt/Nginx/sbin:$PATH"' > /etc/profile.d/Nginx.sh
# 运行fpm需要安装的rpmbulid
[root@66technicians ~]# yum install -y rpm-build
# 将Nginx做成rpm包
[root@66technicians ~]# fpm -s dir -t rpm -n Nginx -d 'openssl-devel,pcre-devel' --post-install /root/post_Nginx.sh -f /opt/Nginx-1.20.2/

Created package {:path=>"Nginx-1.0-1.x86_64.rpm"}
源码安装Nginx
# 1.Nginx官网，下载源码包
https://Nginx.org/
# 2.下载
[root@28technicians ~]# wegt https://Nginx.org/download/Nginx-1.20.2.tar.gz
2.1 查看
[root@28technicians ~]# ll
-rw-r--r--1 root root 1062124 Nov 1622:51 Nginx-1.20.2.tar.gz
# 3.解压
[root@28technicians ~]# tar xf Nginx-1.20.2.tar.gz
# 4.安装依赖包
1.生成依赖包命令
[root@28technicians ~]# ./configure --prefix=/opt/Nginx-1.20.2 --with-http_ssl_module --with-http_stub_status_module
2.安装依赖包
[root@28technicians ~]# yum install -y pcre-devel openssl-devel gcc gcc-c++ glibczlib-devel
'报错解决'
报错1.
./configure: error: C compiler cc is not found
报错原因：缺少C语言环境
解决方法：yum install -ygcc gcc-c++ glibc
报错2.
./configure: error: the HTTP rewrite module requires the PCRE library
报错原因：缺少pcre库文件
解决方法：yum install -y pcre-devl
报错3.
./configure: error: the HTTP rewrite module requires the OpenSSL library
报错原因：缺少openssl库文件
解决方法：yum install -y openssl-devel
