应开发同事的要求,部署了Gitlab+Gerrit+Jenkins的持续集成环境.

但是发现了一个问题,Gerrit登陆后有中文乱码出现.

具体情况如下:

(1)Git代码中的中文乱码处理:

为妥善解决中文编码的问题,对所有git repository做如下约定:
所有文本文件都必须存储成utf8编码
全局配置如下:
git config --global core.quotepath false
git config --global i18n.logoutputencoding utf8
git config --global i18n.commitencoding utf8

另外:安装gerrit的时候对于数据库(选择myqsl方式的话)的编码设定为utf8

(2)Gerrit登陆后,设置中文用户名出现乱码

即在“Full name”一栏中输入中文名后,刷新一下就会出现“???”的乱码,如下:

后来想到,可能是在创建gerrit数据库的时候没有自定义编码为utf8

登陆数据库,查看编码:

mysql> show variables like '%character%';
+--------------------------+----------------------------------+
| Variable_name | Value |
+--------------------------+----------------------------------+
| character_set_client        | utf8 |
| character_set_connection | utf8 |
| character_set_database    | utf8 |
| character_set_filesystem  | binary |
| character_set_results       | utf8 |
| character_set_server    | latin1 |
| character_set_system       | utf8 |
| character_sets_dir | /usr/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)

发现直接查询目标表,不支持中文:

mysql> use gerritdb;
Database changed
mysql> select full_name,account_id from accounts;
+-----------+------------+
| full_name | account_id |
+-----------+------------+
| daizizhe | 5 |
| gerrit | 1 |
| jenkins | 3 |
| wangshibo | 2 |
+-----------+------------+
4 rows in set (0.00 sec)

mysql> update accounts set full_name = "王士博" where account_id = 2;
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 1

mysql> select full_name,account_id from accounts;
+-----------+------------+
| full_name | account_id |
+-----------+------------+
| ???           | 2 |
| daizizhe     | 5 |
| gerrit        | 1 |
| jenkins      | 3 |
+-----------+------------+
4 rows in set (0.00 sec)

解决办法:

**********************************************

首先保证服务器的系统编码是支持中文的

[root@115 ~]# cat /etc/sysconfig/i18n
LANG="zh_CN.UTF-8"

**********************************************

修改mysql数据库编码为utf8,支持中文

1)临时修改character_set_server的编码

mysql> character_set_server='utf8';

2)永久性生效

修改mysql服务的配置文件/etc/my.cnf

[root@115 ~]# vim /etc/my.cnf

.......

[mysqld]

......

character_set_server = utf8            【添加这一行内容】

然后重启mysql服务

[root@115 ~]# /etc/init.d/mysqld restart
Shutting down MySQL. [确定]
Starting MySQL.. [确定]

**********************************************

已经修改了mysql的编码,保证各个编码参数均为utf8了,如下:

mysql> show variables like '%character%';
+--------------------------+----------------------------------+
| Variable_name | Value |
+--------------------------+----------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql/share/charsets/ |
+--------------------------+----------------------------------+
8 rows in set (0.00 sec)

但是发现Gerrit里面的“Full name”设置成中文名还是乱码

最后发现这是因为“Full name”字段所在的表结构了就已经写死了编码为latin1

先mysqldump到处gerritdb数据库

[root@115 ~]#mysqldump gerritdb -p > gerritdb.sql

然后查看gerritdb.sql备份文件

发现gerritdb库里所有表的编码都是latin1啊!!!!

[root@115 ~]#vim gerritdb.sql

补救措施:

现将gerritdb.sql备份文件里的latin1_bin替换成utf8_general_ci

再将gerritdb.sql备份文件里的latin1替换成utf8

vim替换如下:

:%s/latin1_bin/utf8_general_ci/g
:%s/latin1/utf8/g

接着删除gerritdb数据库

再创建空的gerritdb库,创建的时候指定编码为utf8

mysql>drop database gerritdb;

mysql>create database gerritdb CHARACTER SET utf8 COLLATE utf8_general_ci;

最后再将修改好的gerritdb.sql备份文件(已经修改编码为utf8了)导入到gerritdb空库呢

[root@115 ~]#mysql  gerritdb -p < gerritdb.sql

检查下,发现可以支持中文了

mysql> use gerritdb;
Database changed
mysql> select full_name,account_id from accounts;
+-----------+------------+
| full_name | account_id |
+-----------+------------+
| daizizhe | 5 |
| gerrit | 1 |
| jenkins | 3 |
| wangshibo | 2 |
+-----------+------------+
4 rows in set (0.00 sec)

mysql> update accounts set full_name = "王士博" where account_id = 2;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

mysql> select full_name,account_id from accounts;
+-----------+------------+
| full_name | account_id |
+-----------+------------+
| daizizhe       | 5 |
| gerrit          | 1 |
| jenkins        | 3 |
| 王士博          | 2 |
+-----------+------------+
4 rows in set (0.00 sec)

mysql>
