docker部署nacos详细步骤《一》

1. nacos安装步骤

• 准备安装目录映射docker容器目录

#创建文件夹
cd /opt
ls
mkdir nacos
cd /opt/nacos
mkdir logs data conf
# 将准备好的nacos配置文件application.properties上传到 /opt/nacos/conf目录

# 查看镜像
docker search nacos
# 拉取镜像
docker pull nacos/nacos-server
# 启动镜像
docker run -d  -p 8848:8848 \
--name nacos \
--privileged=true \
--restart=always \
-v /opt/nacos/logs:/home/nacos/logs \
-v /opt/nacos/data:/home/nacos/data \
-v /opt/nacos/conf/application.properties:/home/nacos/conf/application.properties \
-e JVM_XMS=256m \
-e JVM_XMX=256m \
--env PREFER_HOST_MODE=hostname \
--env MODE=standalone \
nacos/nacos-server

• application.properties

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
spring.datasource.platform=${SPRING_DATASOURCE_PLATFORM:""}
nacos.cmdb.dumpTaskInterval=3600
nacos.cmdb.eventTaskInterval=10
nacos.cmdb.labelTaskInterval=300
nacos.cmdb.loadDataAtStart=false
db.num=${MYSQL_DATABASE_NUM:1}
db.url.0=jdbc:mysql://${MYSQL_SERVICE_HOST}:${MYSQL_SERVICE_PORT:3306}/${MYSQL_SERVICE_DB_NAME}?${MYSQL_SERVICE_DB_PARAM:characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false}

db.password=${MYSQL_SERVICE_PASSWORD}
### The auth system to use, currently only 'nacos' is supported:
nacos.core.auth.system.type=${NACOS_AUTH_SYSTEM_TYPE:nacos}


### The token expiration in seconds:
nacos.core.auth.default.token.expire.seconds=${NACOS_AUTH_TOKEN_EXPIRE_SECONDS:18000}

### The default token:
nacos.core.auth.default.token.secret.key=${NACOS_AUTH_TOKEN:SecretKey012345678901234567890123456789012345678901234567890123456789}

### 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.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=${NACOS_AUTH_IDENTITY_KEY:serverIdentity}
nacos.core.auth.server.identity.value=${NACOS_AUTH_IDENTITY_VALUE:security}
server.tomcat.accesslog.enabled=${TOMCAT_ACCESSLOG_ENABLED:false}
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %D
# default current work dir
server.tomcat.basedir=
## spring security config
### turn off security
nacos.security.ignore.urls=${NACOS_SECURITY_IGNORE_URLS:/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**}

• -查看镜像 docker search nacos
  
• 拉取镜像 docker pull nacos/nacos-server
  
• 启动容器

docker run -d  -p 8848:8848 \
--name nacos \
--privileged=true \
--restart=always \
-v /opt/nacos/logs:/home/nacos/logs \
-v /opt/nacos/data:/home/nacos/data \

• docker ps 查看容器是否启动
  
• docker logs -f --tail 500 nacos 查看容器日志，可以看到nacos版本是2.1.0
  

2. 登录nacos

• 启动容器
• 浏览器访问 http://ip:port/nacos
  
• 默认账号密码为nacos/nacos
  

3. 修改nacos密码

4. 创建用户

5. 创建命名空间

6. 角色管理-绑定角色

7. 权限管理-添加权限

8. 配置列表-创建配置文件

• Data ID:可以写项目名称.yml,比如 xxx-user.yml
