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/
no value for epoch is set, defaulting to nil {:level=>:warn}
no value for epoch is set, defaulting to nil {:level=>:warn}
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

# 5.编译

nobody    18386  18385  0 16:55 ?        00:00:00 nginx: worker process
root      18390   7203  0 16:57 pts/0    00:00:00 grep --color=auto nginx

# 11.关闭防火墙
[root@28technicians nginx-1.20.2]# systemctl stop firewalld

# 12.关闭selinux

[root@28technicians conf]# vi nginx.conf
 
     33     #gzip  on;
     34 
     35     server {
     36         listen       80;
     37         server_name  localhost;
     38         location / {
     39             root   /data/yum_data/;
     40             autoindex on;
     41             access_log off;
     42             }
     43         }
     44

[nginx]
name=1
baseurl=http://10.0.0.101/nginx/
gpgcheck=0

# 25.查看yum源仓库
[root@66technicians yum.repos.d]# yum repolist

# 26.安装nginx(查看是否走的自己创建的nginx源)
[root@66technicians yum.repos.d]# yum -y install nginx

# 27.查看环境变量是否添加
[root@66technicians yum.repos.d]# echo $PATH
/opt/nginx/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
[root@66technicians yum.repos.d]# source /etc/profile
[root@66technicians yum.repos.d]# echo $PATH
/opt/nginx/sbin:/opt/nginx/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
