Linux Operation learning------svn/rpm Packaging

1. Subversion Basic operation
is a free/open source version control system (SVN)
Multi-person collaboration documentation and tracking of changes made
1.1 Basic Concepts:
Repository: Is the core of version control; any number of clients; clients share code by writing a database
Subversion features: Record every change
1.2 Version Model
The core task of the version control system is collaborative editing and data sharing

1.3 Building Subversion Services
[Email protected] ~]# yum-y Install subversion #装包
[Email protected] ~]# MKDIR/VAR/SVN
[Email protected] ~]# svnadmin create/var/svn/project #创建共享目录
[Email protected] ~]# Ls/var/svn/project
Conf db format Hooks Locks README.txt
[Email protected] system]# Cd/usr/lib/systemd/system
#导入数据 (experiment with this path as data import)
[[Email protected] system]# SVN import. file:///var/svn/project/-M "First Code"
#-m "Comments"
[Email protected] ~]# SVN list file:///var/svn/project #查看共享目录内的内容
[Email protected] ~]# cd/var/svn/project/#这样是看不到的
1.4 Modifying a configuration file
[Email protected] ~]# vim/var/svn/project/conf/svnserve.conf
Anon-access = None #匿名无任何权限
auth-access = Write #输入密码的账户 (active account) readable and writable
Password-db = passwd #密码文件
Authz-db = Authz #ACL访问控制列表文件
[[email protected] ~]# vim/var/svn/project/conf/passwd #用户名, password file
[Email protected] ~]# Vim/var/svn/project/conf/authz #针对每个文件做权限
[/] #定义ACL访问控制= RW #所有人可以对共享目录rw
[/test] #对/test definition tom = rw #tom rw Harry = r #harry可r
[/ABC]= #所有人不可以
For this case: [/] Tom = rw Harry = RW
1.5 Starting the Service (2 methods)
[[email protected] ~]# svnserve-d-r/var/svn/project/#指定一个目录共享出去-D background
[Email protected] ~]# systemctl start Svnserve #所有目录都共享出去
1.6 Client Testing
[Email protected] ~]# cd/tmp
[[Email protected] tmp]# SVN co--username Tom--password 123456 svn://192.168.2.100/
Code #co: Checkout (check download) user name password where to download the stored directory (automatically create local copy)
[Email protected] code]# vim User.slice #在目录code下随便修改一个文件
[Email protected] code]# svn ci-m "Code2" #改完之后上传 ci (comit)
There are 2 versions of the files that are saved on the server side
1.7 Other commands
[[email protected] code] #svn update #更新数据
[Email protected] ~]# SVN info svn://192.168.2.100 #查看版本仓库信息
[Email protected] ~]# SVN log svn://192.168.2.100 #查看版本修改历史
Add command
Write two scripts test.sh test1.sh
[Email protected] ~]# Cd/tmp/code #需要在本地副本内操作
[[email protected] code] #svn add + filename #本地版本库添加新文件
The current location must be the location of the download file, and the new file needs to be placed in the directory
[[Email protected] code]# SVN list svn://192.168.2.100 | grep test #添加的test. SH did not find
[[Email protected] code]# svn ci-m "add Test"
[[Email protected] code]# SVN list svn://192.168.2.100 | grep test
test.sh
test1.sh
mkdir command
[[Email protected] ~] #svn mkdir + directory
[[Email protected] code]# SVN mkdir test
[[Email protected] code]# CD test
[Email protected] test]# echo "Add test File" > Abc.txt
[[Email protected] test]# SVN add abc.txt
[[Email protected] test]# svn ci-m "mkdir and Add File"
del command
[[Email protected] ~] #svn del + file
#不会自动提交到版本库, local deleted, still exists on the server, requires SVN ci-m
[Email protected] code]# svn ci-m "del test.sh" #真正在库内删除
List command
[[Email protected] ~] #svn list svn://192.168.2.100 #文件列表
[[Email protected] ~] #svn mv/cp/rm
[[email protected] code] #svn diff #本地副本库和服务器中文件对比

Two types of modified replicas
1, local modification, not submitted
[Email protected] code]# vim Zram.service #本地删除里面数据
[Email protected] code]# svn revert zram.service #数据恢复
"Zram.service" has been restored
Revert local copy is modified but not CI committed, data recovery can be
2, local modification, submit
[Email protected] code]# svn merge-r7:5 zram.service #将7版本还原为5版本
[Email protected] tmp]# SVN-R1 Co svn://192.168.2.100 code2
Take out the first version and put it in Code2.

More than 1.8 people collaborate:
Environment: Operations that are logged on by different users on different clients
1. Modify different files
[[Email protected] code]# SVN update
[[Email protected] code]# SVN update
#两台保持相同内容
Web1 Modify a file and upload the version update +1
WEB2 modify another file, upload, version update +2
At this time Web1 modified WEB2 not modified, WEB2 modified WEB1 not modified
The same version of SVN update, respectively, relative to the original +2
2. Modify different contents of the same file
Web1 Modify a file and upload the version update +1
WEB2 Modify the same file, upload, prompt expires, SVN update version update +1 (modified place is not overwritten!!) ), and upload version update +1 (total +2)
WEB1 SVN update Version +1
3, modify the same content of the same file (conflict, think resolved)
Web1 Modify a file and upload the version update +1
WEB2 Modify the same file, upload, prompt expires, SVN update, hint: In "/tmp/code/user.slice" found conflict.
Select: (P) defer, (DF) Show all differences, (e) Edit,
(MC) My version, (TC) Other people's version,
(s) Show all options:
Select p after a few more versions in the directory, delete the not, and then upload

[Email protected] code]# svnadmin dump/var/svn/project/> My.bak #所有版本都进行了备份
[Email protected] code]# svnadmin load/var/svn/project2/< My.bak #还原

2. RPM Package
1). RPM is a compressed package (source after the installation of the directory)
2). RPM contains some descriptive information
2.1 Implementation steps:
1) Install the Rpm-build package
[Email protected] ~]# yum-y install Rpm-build
2) Generate RPMBUILD directory structure
[Email protected] ~]# Rpmbuild-ba xx.spec #生成rpmbuild目录以及子目录
[[email protected] ~]# ls rpmbuild/
BUILD buildroot RPMS SOURCES SPECS SRPMS
SOURCES: directory where source packages are stored
SPECS: Configuration file (basic information, source installation)
BuildRoot: Rhizoids (for rpmbuild This software, packed under this root, does not affect the real root)
RPMS: The position of the finished product, RPM package
3) Prepare to copy the source software to the sources directory
In the case of Nginx source package:
[email protected] ~]# CP lnmp_soft/nginx-1.8.0.tar.gz/root/rpmbuild/sources/
4) Create and modify spec configuration file
[Email protected] ~]# vim Rpmbuild/specs/nginx.spec
Fill in the Software information
LICENSE:GPL #此软件定义为开源
%prep #源码包解包, and CD in
%setup-q

%build #配置编译
%configure #模块化配置, can be replaced by./configure--with-http_ssl_module
Make%{?_smp_mflags}

%files
%doc
/usr/local/nginx/* #将该路径下所有打包
5) Installation Dependencies and packaging
[Email protected] ~]# yum-y install gcc pcre-devel zlib-devel
Openssl-devel (http_ssl_module) need to install this
[Email protected] ~]# CD rpmbuild/
[Email protected] rpmbuild]# Rpmbuild-ba Specs/nginx.spec
[[email protected] ~]# ls rpmbuild/rpms/x86_64/
nginx-1.8.0-40.x86_64.rpm nginx-debuginfo-1.8.0-40.x86_64.rpm
6) can use custom Yum Warehouse installation
