#### selinux_adapter仓修改内容

1.  service_contexts文件修改
```
base/security/selinux_adapter/sepolicy/base/public/service_contexts

7001	                               u:object_r:sa_subsys_ace_service:s0
7002	                               u:object_r:sa_ui_appearance:s0
8001	                               u:object_r:sa_ca_daemon_service:s0
# 添加下面的内容,9000要求升序排列
9000	                               u:object_r:sa_napitestservice_service:s0
```

2.  service.te文件修改
```
base/security/selinux_adapter/sepolicy/base/public/service.te

type sa_ui_appearance, sa_service_attr;
# 添加下面的内容
type sa_napitestservice_service, sa_service_attr;
```

3.  type.te文件修改
```
base/security/selinux_adapter/sepolicy/base/public/type.te
# 添加下面的内容
type napitestservice, sadomain, domain;
```

4.  selinux权限
```
base/security/selinux_adapter/sepolicy/ohos_policy
在ohos_policy目录下面新建自己的目录，例如：napitest/system
添加一个te文件添加权限配置信息
```
你可以 [security_selinux_adapter](https://gitee.com/openharmony/security_selinux_adapter) 这个地址来了解selinux

```
# 快速验证使用下面的命令设置宽容模式
hdc shell "echo SELINUX=permissive > /etc/selinux/config"
```

#### startup仓修改内容

1.  group文件修改
```
base/startup/init/services/etc/group
# 添加下面的内容，3290这个数值不要存在重复项
napitest:x:3290:
```

2.  passwd文件修改
```
base/startup/init/services/etc/passwd
# 添加下面的内容，3290这个数值不要和其它行存在重复项
napitest:x:3290:3290:::/bin/false
```

上面的修改分别对应secon属性、uid和gid属性（使用root和system）可以不用修改startup仓。
```
{
    "services" : [{
            "name" : "napitestservice",
            "path" : ["/system/bin/sa_main", "/system/profile/napitestservice.json"],
            "uid" : "napitest",
            "gid" : ["napitest", "shell"],
            "secon": "u:r:napitestservice:s0",
            "permission" : []
        }
    ]
}
```
#### samgr仓修改内容

1.  修改头文件
```
foundation/systemabilitymgr/samgr/interfaces/innerkits/samgr_proxy/include/system_ability_definition.h

    CA_DAEMON_ID                                     = 8001,
    ASSET_SERVICE_ID                                 = 8100,
# 添加下面的内容,9000要求升序排列
    TEST_SERVICE_ID                                  = 9000,
```

对应的是sa的profile文件
```
{
  "process":"napitestservice",
      "systemability":[
          {
              "name":9000,
              "libpath":"libnapi_test_service.z.so",
              "run-on-create":false,
              "auto-restart":true,
              "distributed":false,
              "dump-level":1
          }
      ]
}
```

#### 日志打印
```
base/hiviewdfx/hilog/services/hilogd/log_domains.cpp
    {0xD005D00, "XTS"},
    {0xD00AD00, "ASystem"},
    # 添加自己定义的log domain和target，也可以使用已有的domain定义自己的TAG。例如添加一个
    {0xD00D200, "NAPI_TEST"},
}, __UINT32_MAX__, "Invalid");
```
