源码编译环境
- 服务器 Alibaba Cloud Linux 3.2104 64位
- Maven apache-maven-3.8.4
- JDK 1.8.0_291编译成功
java -version
java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)
- OpenJDK 11 编译失败
java -version

编译准备
- 1、配置JAVA_HOME
通过 vim /etc/profile编辑profile文件，配置JAVA_HOME，并通过 source /etc/profile刷新配置。示例如下：
[root@aliyun ~]# cat /etc/profile
jdk8
export JAVA_HOME=/data/source/jdk1.8.0_202
openjdk11
#export JAVA_HOME=/usr/local/jdk-11
export CLASSPATH=$JAVA_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$PATH
- 2、配置maven
通过 vim ~/.bash_profile编辑.bash_profile文件，配置MAVEN_HOME，并通过 source ~/.bash_profile刷新配置。示例如下：
#JAVA_HOME CONFIG IN /etc/profile
#JAVA_HOME=/usr/local/jdk-11
#JAVA_HOME=/data/source/jdk1.8.0_202
#export JAVA_HOME
MAVEN_HOME=/data/app/apache-maven-3.8.4
PATH=$PATH:$HOME/bin:$MAVEN_HOME/bin
export PATH
在 /data/app/apache-maven-3.8.4/conf/settings.xml的mirrors节点添加aliyun maven镜像源。
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorof>central</mirrorof>
</mirror>
命令
编译打包
cd /data/source
从git拉取最新代码
git clone https://github.com/alibaba/nacos.git
cd nacos
切换到master主分支，并通过git log确认当前commit为b584531331cc95054964ba4e33984f4cab9e582d
git checkout master
cherry-pick 74c3355b712e74e8274ac038470dc3db411b7c9e，解决nacosAuthConfig jwtTokenManager之间的circular reference
git cherry-pick 74c3355b712e74e8274ac038470dc3db411b7c9e
编译
mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U
- 打包命令
mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U 【推荐】
mvn -Prelease-nacos clean install -U -DskipTests -Drat.skip=true

解压部署的jar包
copy 需要部署的jar包
cp distribution/target/nacos-server-2.1.0.tar.gz /data/app/nacos-server-2.1.0.tar.gz
cd /data/app
解压
tar -xvzf nacos-server-2.1.0.tar.gz
配置调整
应用配置文件application.properties
修改DB连接串
将 nacos/conf/application.properties的第33~41行DB配置信息根据实际情况修改，并取消注释
31 #*************** Config Module Related Configurations ***************#
32 ### If use MySQL as datasource:
33 spring.datasource.platform=mysql
34
35 ### Count of DB:
36 db.num=1
37
38 ### Connect URL of DB:
39 db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
40 db.user.0=nacos
41 db.password.0=nacos
注意点
- DB名称： 名称可由服务器所采用的字符集中任意字母、数字、”_”和” $”组成。如果需要其他字符，需要使用[
]包裹起来，例如db-nacos。已踩坑未验证</li> <li>db.url：增加allowPublicKeyRetrieval=true。 已踩坑已验证</li> </ul> <h5>修改服务端口</h5> <p>可先跳过，按顺序查看【批量服务端口】章节</p> <h4>启动文件startup.sh</h4> <p>根据硬件资源及实际情况，在 <code>nacos/bin/startup.sh</code>文件中调整JVM参数</p> <pre><code> 93 #JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m" 94 JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx256m -Xmn64m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m" </code></pre> <h5>JVM参数</h5> <p>Xss：每个线程的stack大小（栈） Xmx：JAVA HEAP的最大值、默认为物理内存的1/4 Xms：JAVA HEAP的初始值，server端最好Xms与Xmx一样 Xmn：JAVA HEAP young区的大小 XX:MetaspaceSiz：设定内存的永久保存区域 XX:MaxMetaspaceSiz：设定最大内存的永久保存区域</p> <h5>编码问题</h5> <pre><code>[root@aliyun app]# sh nacos/bin/startup.sh startup.sh: line 2: $'\r': command not found startup.sh: line 7: $'\r': command not found startup.sh: line 15: $'\r': command not found startup.sh: line 19: syntax error near unexpected token$’in\r”
‘tartup.sh: line 19:case "`" in
则可以执行
sed -i 's/\r//g' nacos/bin/*全局替换回车符。
原因
脚本是在Windows下编辑完成后上传Linux上执行的，Windows下的换行是回车符+换行符，也就是\r\n,而Linux下是换行符\n。Linux下不识别\r为回车符，所以导致每行的配置都多了个\r，因此是编码的问题。日志

Tomcat started on port(s): 8848 (http) with context path '/nacos'、Nacos started successfully in cluster mode. use external storage等信息，表示启动成功。
访问http://localhost:8848/nacos/，如下图：
以上为单节点，继续修改配置，在单服务器部署集群。生产环境，必须在多服务器上部署集群，一台服务器上禁止部署多个nacos节点。同时也不用考虑单机节点冲突问题。个人学习因服务器硬件资源有限，选择单服务器部署所有服务。
部署集群
集群配置文件cluster.conf
cat << EOF > nacos3/conf/cluster.conf 172.18.155.8:18848 172.18.155.8:28848 172.18.155.8:38848 EOF复制多节点
复制节点2：nacos2 cp -r nacos nacos2 复制节点3：nacos3 cp -r nacos nacos3 将nacos节点移动为节点1：nacos1 mv nacos nacos1 修改端口号 sed -i 's/8848/18848/g' nacos1/conf/application.properties sed -i 's/8848/28848/g' nacos2/conf/application.properties sed -i 's/8848/38848/g' nacos3/conf/application.properties服务端口
raft port: ${server.port} – 1000
grpc port: ${server.port} + 1000
grpc port for server: ${server.port} + 1001
假设对外端口为8848，即总共会有4个端口被占用，分别为7848、8848、9848、9849。所以单服务器部署集群时，端口不要太集中。未踩坑未验证启动集群
