Nacos适配达梦数据库并制作镜像

背景：因项目需要信创，需将原本的mysql数据库，改成达梦数据库

一、部署达梦数据库

1.1 部署达梦数据库服务

可参考：Docker安装达梦数据库_达梦数据库docker镜像-CSDN博客

1.2 创建nacos数据库

create user SAFE_NACOS identified by "Safehub@2024";

grant "PUBLIC","SOI","VTI" to "SAFE_NACOS";

grant create table to "SAFE_NACOS";

CREATE SCHEMA "SAFE_NACOS" AUTHORIZATION "SAFE_NACOS";

1.3 适配了达梦的nacos脚本

二、nacos适配达梦数据库

这里以nacos-2.1.0为例子

2.1 下载nacos2.1.0源码

可参考：GitHub - alibaba/nacos at 2.1.0

2.2 修改nacos源码以适配达梦数据库

2.2.1 引入达梦驱动依赖

首先在根目录的pom.xml中引入达梦数据库依赖

<dm-connector-java.version>8.1.1.49</dm-connector-java.version>

<dependency>

                <groupId>com.dameng</groupId>

                <artifactId>Dm8JdbcDriver18</artifactId>

                <version>${dm-connector-java.version}</version>

</dependency>

2.2.2 修改nacos-config模块下的ExternalDataSourceProperties

具体代码如下：

public class ExternalDataSourceProperties {private static final String JDBC_DRIVER_NAME = "com.mysql.cj.jdbc.Driver";private static final String TEST_QUERY = "SELECT 1";private Integer num;private String jdbcDriverName;private List<String> url = new ArrayList<>();private List<String> user = new ArrayList<>();private List<String> password = new ArrayList<>();public void setNum(Integer num) {this.num = num;}public void setUrl(List<String> url) {this.url = url;}public void setUser(List<String> user) {this.user = user;}public void setPassword(List<String> password) {this.password = password;}public String getJdbcDriverName() {return jdbcDriverName;}public void setJdbcDriverName(String jdbcDriverName) {this.jdbcDriverName = jdbcDriverName;}/*** Build serveral HikariDataSource.** @param environment {@link Environment}* @param callback    Callback function when constructing data source* @return List of {@link HikariDataSource}*/List<HikariDataSource> build(Environment environment, Callback<HikariDataSource> callback) {List<HikariDataSource> dataSources = new ArrayList<>();Binder.get(environment).bind("db", Bindable.ofInstance(this));Preconditions.checkArgument(Objects.nonNull(num), "db.num is null");Preconditions.checkArgument(CollectionUtils.isNotEmpty(user), "db.user or db.user.[index] is null");Preconditions.checkArgument(CollectionUtils.isNotEmpty(password), "db.password or db.password.[index] is null");for (int index = 0; index < num; index++) {int currentSize = index + 1;Preconditions.checkArgument(url.size() >= currentSize, "db.url.%s is null", index);DataSourcePoolProperties poolProperties = DataSourcePoolProperties.build(environment);poolProperties.setDriverClassName(JDBC_DRIVER_NAME);poolProperties.setJdbcUrl(url.get(index).trim());poolProperties.setUsername(getOrDefault(user, index, user.get(0)).trim());poolProperties.setPassword(getOrDefault(password, index, password.get(0)).trim());HikariDataSource ds = poolProperties.getDataSource();ds.setConnectionTestQuery(TEST_QUERY);ds.setIdleTimeout(TimeUnit.MINUTES.toMillis(10L));ds.setConnectionTimeout(TimeUnit.SECONDS.toMillis(3L));System.out.println("#################################");System.out.println("jdbcDriverName=" + jdbcDriverName);if (StringUtils.isNotEmpty(jdbcDriverName)) {// 增加其他数据库驱动的支持ds.setDriverClassName(jdbcDriverName);} else {//默认使用mysql驱动ds.setDriverClassName(JDBC_DRIVER_NAME);}System.out.println("#################################");System.out.println("dataSources=" + dataSources);dataSources.add(ds);callback.accept(ds);}Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");return dataSources;}interface Callback<D> {/*** Perform custom logic.** @param datasource dataSource.*/void accept(D datasource);}
}

2.2.3 修改nacos-console模块下的application.properties

### Count of DB:

db.num=1

db.jdbcDriverName=dm.jdbc.driver.DmDriver

db.url.0=jdbc:dm://10.136.xxx.xxx:5237?schema=SAFE_NACOS&characterEncoding=UTF-8&useUnicode=true&serverTimezone=Asia/Shanghai

db.user=SAFE_NACOS

db.password=Safehub@2024

2.3 重新打包nacos

在nacos项目下打开终端输入以下命令

mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Dcheckstyle.skip=true clean install -U

运行成功后会在/nacos/distribution/target目录下生成如下文件

至此，新的nacos已改造完成。

三、制作nacos-dm.tar镜像

3.1 编写Dockerfile文件

vi Dockerfile

FROM java:8

MAINTAINER wx

ENV JAVA_HOME=/usr/lib/jvm/jdk1.8.0_181

ENV PATH=$PATH:$JAVA_HOME/bin

ENV LC_ALL=en_US.utf8

ENV LANG=en_US.utf8

ENV LANGUAGE=en_US.utf8

ADD nacos-server.jar app.jar

EXPOSE 8848

ENTRYPOINT ["java", "-Dfile.encoding=utf-8","-jar", "app.jar"]

PS：docker已有基础镜像java:8

3.2 编写构建镜像脚本

vi nacos_built.sh（PS：Dockerfile和jar包在同一目录下）

app_name='nacos-dm'

docker stop ${app_name}

docker rm -f ${app_name}

sleep 2

docker build -t nacos-dm .

3.3 启动nacos-dm容器

3.3.1 创建/home/nacos/mydata/conf/，/home/nacos/mydata/logs目录

并将下面两个文件copy进/home/nacos/mydata/conf/

3.3.2 修改application.properties文件

application.properties完整内容如下：

# spring

server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}

server.contextPath=/nacos

server.port=${NACOS_APPLICATION_PORT:8848}

server.tomcat.accesslog.max-days=30

server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i

server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}

server.error.include-message=ALWAYS

# default current work dir

server.tomcat.basedir=file:.

#*************** Config Module Related Configurations ***************#

### Deprecated configuration property, it is recommended to use `spring.sql.init.platform` replaced.

#spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:}

spring.sql.init.platform=${SPRING_DATASOURCE_PLATFORM:dm}

nacos.cmdb.dumpTaskInterval=3600

nacos.cmdb.eventTaskInterval=10

nacos.cmdb.labelTaskInterval=300

nacos.cmdb.loadDataAtStart=false

db,jdbcDriverName=${DM_DRIVER:dm.jdbc.driver.DmDriver}

db.num=${MYSQL_DATABASE_NUM:1}

db.url.0=jdbc:dm://${MYSQL_SERVICE_HOST:10.136.xxx.xx}:${MYSQL_SERVICE_PORT:5237}/${MYSQL_SERVICE_DB_NAME:SAFE_NACOS}?${MYSQL_SERVICE_DB_PARAM:characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false}

db.user.0=${MYSQL_SERVICE_USER:SAFE_NACOS}

db.password.0=${MYSQL_SERVICE_PASSWORD:Safehub@2024}

### The auth system to use, currently only 'nacos' and 'ldap' is supported:

nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}

### worked when nacos.core.auth.system.type=nacos

### The token expiration in seconds:

nacos.core.auth.plugin.nacos.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

### The default token:

nacos.core.auth.plugin.nacos.token.secret.key=${NACOS_AUTH_TOKEN:SecretKey01234567890123456789012345345678999987654901234567890123456789}

### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.

nacos.core.auth.enable=true

nacos.core.auth.caching.enabled=${NACOS_AUTH_CACHE_ENABLE:false}

nacos.core.auth.enable.userAgentAuthWhite=${NACOS_AUTH_USER_AGENT_AUTH_WHITE_ENABLE:false}

nacos.core.auth.server.identity.key=${NACOS_AUTH_IDENTITY_KEY:example}

nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:example}

## spring security config

### turn off security

nacos.security.ignore.urls=${NACOS_SECURITY_IGNORE_URLS:/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**}

# metrics for elastic search

management.metrics.export.elastic.enabled=false

management.metrics.export.influx.enabled=false

nacos.naming.distro.taskDispatchThreadCount=10

nacos.naming.distro.taskDispatchPeriod=200

nacos.naming.distro.batchSyncKeyCount=1000

nacos.naming.distro.initDataRatio=0.9

nacos.naming.distro.syncRetryDelay=5000

nacos.naming.data.warmup=true

3.3.3 编写cluster.conf

目前内容为空

3.4 编写启动脚本

vi docker-startup.sh

app_name='nacos-dm'

docker stop ${app_name}

echo '--------stop container-------------'

docker rm ${app_name}

echo '--------rm container---------------'

docker run -p 8848:8848 --name ${app_name} \

        -e MODE=standalone \

        -e TZ="Asia/Shanghai"\

        --restart always\

        -v /etc/localtime:/etc/localtime \

        -v /home/nacos/mydata/conf/:/root/nacos/conf/ \

        -v /home/nacos/mydata/logs/:/root/nacos/logs \

        -d ${app_name}

echo '---------start container---------'

3.5 打成tar包

docker save -o nacos-dm.tar nacos-dm

四、遇到的问题

4.1 出现错误：[Too many errors, abort] [error occurred during error reporting , id 0xb]

可能是docker容器问题,添加docker内存配置：

vi /etc/profile

ulimit -n 65535

vi /etc/systemd/system/docker.service

ExecReload=/bin/kill -s HUP $MAINPID

LimitNOFILE=65535

LimitNPROC=65535

LimitCORE=65535

然后重启加载配置并启动

systemctl daemon-reload

systemctl restart docker

4.2 container_linux.go:318 permission denied””: unknown

改写启动脚本，增加：--privileged=true

app_name='nacos-dm'
docker stop ${app_name}
echo '--------stop container-------------'

docker rm ${app_name}
echo '--------rm container---------------'

docker run -p 8848:8848 --name ${app_name} \
-e MODE=standalone \
-m 3g \
--privileged=true \
   -e TZ="Asia/Shanghai" \
--restart always \
   -v /etc/localtime:/etc/localtime \
-v /home/nacos/mydata/conf/:/root/nacos/conf/ \
   -v /home/nacos/mydata/logs/:/root/nacos/logs \
   -d ${app_name}

echo '---------start container---------'
