FE 开发环境搭建 - Intellj IDEA	zh-CN

使用 Intellj IDEA 搭建 FE 开发环境

1.环境准备

JDK1.8+ , Intellj IDEA

从 https://github.com/apache/incubator-doris.git 下载源码到本地
使用Intellj IDEA 打开代码根目录
如果仅进行fe开发而没有编译过thirdparty，则需要安装thrift，并将thrift 复制或者连接到 thirdparty/installed/bin 目录下
1. 安装 thrift 0.9.3 版本。
  
  MacOS: brew install https://gist.githubusercontent.com/chrislusf/8b4e7c19551ba220232f037b43c0eaf3/raw/01465b867b8ef9af7c7c3fa830c83666c825122d/thrift.rb
  
  Windows: http://archive.apache.org/dist/thrift/0.9.3/thrift-0.9.3.exe
如果是Mac 或者 Linux 环境可以通过如下命令生成自动生成代码：
```
cd fe
mvn  generate-sources
```
如果出现错误，请先执行：
```
cd fe && mvn install -DskipTests
```

或者通过图形界面运行运行maven 命令生成

如果使用windows环境可能会有make命令和sh脚本无法执行的情况可以通过拷贝linux上的 fe/fe-core/target/generated-sources 目录拷贝到相应的目录的方式实现，也可以通过docker 镜像挂载本地目录之后，在docker 内部生成自动生成代码，可以参照编译一节

2.调试

1. 用idea导入fe工程；

2.在fe目录下创建下面红框标出的目录，并将webroot里的内容拷贝进去

3.配置conf/fe.conf

下面是我自己的配置，你可以根据自己的需要进行修改

# Choose one if there are more than one ip except loopback address.

# Default value is empty.

# sys_log_roll_num = 10

# audit_log_modules = slow_query, query
# audit_log_roll_num = 10

# qe_max_connection = 1024
# max_conn_per_user = 100
# qe_query_timeout_second = 300
# qe_slow_log_ms = 5000

4.设置环境变量

在IDEA中设置运行环境变量

5.启动fe

下面你就可以愉快的启动，调试你的FE了
