九、扩展
一、安装软件包的三种方法
1.二进制包（Centos是RPM格式，Debian是Deb格式）
2.Yum在线安装
3.源代码包安装
其实还有脚本安装方式。一般一个源代码包的安装最好是查看一下README和INSTALL文件。
二、rpm包介绍
rpm是Redhat Package Manager的缩写，是由Redhat提出，用于管理linux系统的软件包。
RPM包的名称一般为：名称-版本-发布序列号-软件平台-硬件平台.扩展名
挂载光盘镜像
虚拟机加载光盘镜像ISO文件
挂载光盘
[root@localhost ~]# mkdir /mnt/cdrom
[root@localhost ~]# mount /dev/sr0 /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
RPM包所在位置
[root@localhost ~]# ls /mnt/cdrom/Packages/ | head -n 5
389-ds-base-1.3.1.6-25.el7.x86_64.rpm
389-ds-base-libs-1.3.1.6-25.el7.x86_64.rpm
abattis-cantarell-fonts-0.0.12-3.el7.noarch.rpm
abrt-2.1.11-12.el7.centos.x86_64.rpm
abrt-addon-ccpp-2.1.11-12.el7.centos.x86_64.rpm
三、RPM工具用法
rpm工具常用选项
-i 安装
-U 升级软件包
-V 显示详细安装信息
-h 以安装信息列显示安装进度
-e 卸载rpm包
-q 查询软件包
-qi 查询已安装的指定包信息
-ql 列出一个包安装的文件
-qf 查看命令由哪个安装包而来
-qd 查看文档安装位置
-qpi 查看未安装rpm包的信息
-qpl 查看未安装rpm包将要安装哪些文件
-qpR 查看软件包的依赖关系
--nodeps 在升级或安装rpm包时不检查其依赖关系
--test 并不真正安装rpm包，检测并报告可能的冲突

如果下载已经安装过的rpm包会提示已经安装，不会重新安装。除了卸载已经安装的包重新下载外还有一个方法：yum reinstall
[root@localhost packages]# yum install -y dos2unix
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Package dos2unix-6.0.3-4.el7.x86_64 already installed and latest version
Nothing to do
[root@localhost packages]# yum reinstall -y dos2unix

八、源码代包安装
约定：源码包下载好后放到/usr/local/src/下
下载nginx包
[root@localhost src]# wget http://nginx.org/download/nginx-1.14.0.tar.gz
--2018-05-30 02:58:08-- http://nginx.org/download/nginx-1.14.0.tar.gz

解压源码包
[root@localhost src]# tar -xvf nginx-1.14.0.tar.gz
安装所需的依赖
[root@localhost src]# yum -y install pcre.x86_64 pcre-devel.x86_64
[root@localhost yum.repos.d]# yum -y install openssl openssl-devel
新建nginx安装目录以及nginx用户
[root@localhost src]# cd nginx-1.14.0
[root@localhost nginx-1.14.0]# mkdir -p /application/nginx-1.14
[root@localhost nginx-1.14.0]# useradd nginx -M -s /sbin/nologin
配置选项
[root@localhost nginx-1.14.0]# ./configure --user=nginx --group=nginx --prefix=/application/nginx-1.14/ --with-http_stub_status_module --with-http_ssl_module
编译、安装
[root@localhost nginx-1.14.0]# make && make install
[root@localhost nginx-1.14.0]# ln -s /application/nginx-1.14/ /application/nginx
[root@localhost nginx-1.14.0]# ll /application/
total 0
lrwxrwxrwx 1 root root 24 May 30 03:34 nginx -> /application/nginx-1.14/
drwxr-xr-x 6 root root 50 May 30 03:33 nginx-1.14
启动nginx
[root@localhost ~]# /application/nginx/sbin/nginx
[root@localhost ~]# netstat -nltup | grep :80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 10928/nginx: master
[root@localhost ~]# curl 127.0.0.1
<!DOCTYPE html>

九、扩展
搭建一个局域网http的yum源
创建rpm包存放目录
[root@localhost ~]# mkdir -p /data/yumdata
拷贝ISO镜像文件中的rpm包到/data/yumdata/
root@localhost ~]# cp /mnt/cdrom/Packages/*.rpm /data/yumdata/
创建repository
[root@localhost ~]# createrepo /data/yumdata/
Spawning worker 0 with 1769 pkgs
Spawning worker 1 with 1769 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete
如果rpm包有增加，可执行
createrepo --update /data/yumdata/
利用第八节编译安装的nginx提供http服务
修改nginx的配置文件
[root@localhost ~]# vim /application/nginx-1.14/conf/nginx.conf
35 server {
36 listen 80;
37 server_name localhost;
38 root /data/yumdata;
39 #charset koi8-r;
40
41 #access_log logs/host.access.log main;
42
43 location / {
44 autoindex on;
45 }
46
47
48 #error_page 404 /404.html;
49
50 # redirect server error pages to the static page /50x.html
51 #
52 error_page 500 502 503 504 /50x.html;
53 location = /50x.html {
54 root html;
55 }
[root@localhost ~]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.14//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.14//conf/nginx.conf test is successful
重载nginx配置文件
[root@localhost ~]# /application/nginx/sbin/nginx -s reload
客户端上配置repo文件
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# mkdir bak
[root@localhost yum.repos.d]# mv CentOS* bak/
[root@localhost yum.repos.d]# mv epel* bak/
[root@localhost yum.repos.d]# vim my.repo
1 [hjm]
2 name=myserver
3 baseurl=http://192.168.1.6
4 gpgcheck=0
5 enabled=1
[root@localhost yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: epel hjm
Cleaning up everything
Cleaning up list of fastest mirrors
[root@localhost yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
hjm | 2.9 kB 00:00:00
(1/3): hjm/filelists_db | 2.8 MB 00:00:00
(2/3): hjm/primary_db | 2.7 MB 00:00:00
(3/3): hjm/other_db | 1.1 MB 00:00:00
Determining fastest mirrors
Metadata Cache Created
[root@localhost yum.repos.d]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id repo name status
hjm myserver 3,538
repolist: 3,538
做一个镜像yum源
[root@localhost yum.repos.d]# rsync -av rsync://rsync.mirrors.ustc.edu.cn/centos/7/os/x86_64/Packages/ /data/yumdata/
当局域网的rpm库有更新时，除了服务端执行“createrepo –update /data/yumdata/”外，客户端上也需要执行
yum clean all
yum makecache
