git gerrit 版本控制

git安装

先查看是否已经安装git（centos 7.X 的git版本是1.8）

[root@localhost ~]# git version
git version 1.8.3.1
[root@localhost ~]# yum remove git
Loaded plugins: fastestmirror, langpacks
Existing lock /var/run/yum.pid: another copy is running as pid 93772.
Another app is currently holding the yum lock; waiting for it to exit...
  The other application is: yum
    Memory :  66 M RSS (382 MB VSZ)
    Started: Fri Mar 31 10:44:20 2017 - 07:31 ago
    State  : Traced/Stopped, pid: 93772

执行命令，释放yum

[root@localhost ~]# rm -f /var/run/yum.pid 
[root@localhost ~]#
[root@localhost ~]# yum remove git

删除成功后，安装git

1、安装所需软件包

[root@localhost ~] yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel 
[root@localhost ~] yum install gcc perl-ExtUtils-MakeMaker

2、下载&安装

[root@localhost ~]# cd /usr/local/soft-package
[root@localhost soft-package]# wget https://www.kernel.org/pub/software/scm/git/git-2.7.3.tar.gz
[root@localhost soft-package]# tar -zxvf git-2.7.3.tar.gz
[root@localhost git-2.7.3]# cd git-2.7.3
[root@localhost git-2.7.3]# mkdir /usr/local/install/git
[root@localhost git-2.7.3]# make prefix=/usr/local/install/git all
[root@localhost git-2.7.3]# make prefix=/usr/local/install/git install
[root@localhost git-2.7.3]# echo "export PATH=$PATH:/usr/local/install/git/bin" >> /etc/bashrc
[root@localhost git-2.7.3]# source /etc/bashrc
[root@localhost git-2.7.3]# cd /usr/local/install
[root@localhost install]# git --version
git version 2.7.3
[root@localhost install]#

配置用户

设置git的用户名和email：

[root@localhost install]# git config --global user.name 'yangyp8110'
[root@localhost install]# git config --global user.email yangyp8110@126.com
[root@localhost install]# cd ~/.ssh
-bash: cd: /root/.ssh: No such file or directory
[root@localhost install]#

如果没有git仓库，可以初始化一个repository，后面gerrit安装时会用到

[root@localhost local]# git init --bare /usr/local/gitRepository/example.git
Initialized empty Git repository in /usr/local/gitRepository/example.git/
[root@localhost local]#

生成ssh（可以不用配置，如果出现附录的错误1，按此方法解决）：
- 不输入路径，默认保存地址/root/.ssh/id_rsa
- 直接enter，不输入密码
```
  Enter passphrase (empty for no passphrase):   
  Enter same passphrase again:  
```

[root@localhost install]# ssh-keygen -t rsa -C 'yangyp8110@126.com'
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
9f:00:18:d7:fd:f2:5c:d8:14:ba:22:6c:98:c8:47:ca yangyp8110@126.com
The key's randomart image is:
+--[ RSA 2048]----+
|    . .. .    .. |
|     +  . .  ..  |
|    . o    ..+   |
|   o + =  . o.o  |
|    E + S .+..   |
|     . . + oo    |
|          o      |
|                 |
|                 |
+-----------------+
[root@localhost install]#

最后得到了两个文件：id_rsa和id_rsa.pub

复制~/.ssh/id_rsa.pub里的内容添加到github
- 复制id_rsa.pub里面的全部内容
- 打开github》settings》SSH and GPK keys》New SSH Key，粘贴保存

查看java版本，Centos 7.X 的version应该是 1.7 （安装jdk1.8请参考：jdk8）

[root@localhost install]# java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
[root@localhost install]#

安装MySQL(也可不装使用gerrit默认的h2也行)

安装请参考：MySQL安装

安装gerrit

先要做一下准备工作在mysql中配置一下gerrit要用的库

# 创建用户
mysql> create user 'gerrit001'@'localhost' identified by 'qwer123';
Query OK, 0 rows affected (0.11 sec)

# 创建gerrit要用的数据库
mysql> create database reviewdb;
Query OK, 1 row affected (0.02 sec)

# 设定编码为latin1, 中文不支持   设为utf8会有其它问题
mysql> alter database reviewdb charset=latin1;
Query OK, 1 row affected (0.24 sec)

# 把reviewdb的所有权限赋给gerrit001
mysql> grant all on reviewdb.* to 'gerrit001'@'localhost';
Query OK, 0 rows affected (0.12 sec)

# 刷新权限
mysql> flush privileges;
Query OK, 0 rows affected (0.17 sec)

新建 linux 用户 gerrit001，并切换到 gerrit001 用户

[root@localhost ~]# adduser gerrit001
[root@localhost ~]# su gerrit001
ABRT has detected 2 problem(s). For more info run: abrt-cli list
[gerrit001@localhost root]$

下载Gerrit的java包（war包）
- 官方地址：gerrit-2.12.2
- csdn下载：gerrit-2.11.2
安装

注意事项
- 我们安装的时候，可以只在 Authentication method 时输入 http ，其他全部回车用默认值，因为其他配置我们待会可以通过 etc/gerrit.config 文件进行修改
- 期间可能会下载两个文件，这两个文件虽然都很小(不到3M)，但是可能是因为GFW的原因，下载速度很慢。你可以到 /lib 文件夹下面查看他们是不是已经下载完了，或者你手动把那两个文件下载完之后，scp到 /lib 下面。
- 在安装 http://www.bouncycastle.org/download/bcpkix-jdk15on-151.jar 时失败了，没关系，继续往下走，一路enter，直至安装成功。
- 如果你发现已经下完了，但是安装过程卡主了，没有关系，直接 ctrl+c 然后重新安装就可以了。

# 在gerrit-2.11.2.war所在目录执行如下命令，如果不存目录gerrit_site，会自动创建目录gerrit_site
[gerrit001@localhost ~]$ java -jar gerrit-2.11.2.war init -d ~/gerrit_site

默认配置安装完成了。

下载失败处理方法：
安装过程中会下载下面三个文件，也可以手工下载并拷贝到gerrit_site/lib目录中：
- bcpkix-jdk15on-151.jar——可以在以后添加到gerrit_site/lib
- bcprov-jdk15on-151.jar——可以在以后添加到gerrit_site/lib
- mysql-connector-java-5.1.21.jar——可以在以后添加到gerrit_site/lib，使用mysql时必须安装
启动gerrit：

[gerrit001@localhost gerrit_site]$ ./bin/gerrit.sh start 如果报错如下：
