1.下载地址
https://github.com/alibaba/nacos/releases/tag/2.1.2
2.解压到指定目录并修改配置
修改conf/application.properties配置文件的数据库配置，去掉以下几个配置注释，设 置正确的数据库链接配置
### Count of DB:
db.num=1
### Connect URL of DB:
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
db.user.0=nacos
db.password.0=nacos
# 如需放开鉴权，需要登陆的话，还需要修改以下配置
nacos.core.auth.enabled=true
nacos.core.auth.server.identity.key=akim
nacos.core.auth.server.identity.value=123456
# base64 字符串，自己生成

1.libstdc++.so.6: cannot open shared object file: No such file or directory问题的解决:
1.安装libstdc++.so.6
yum whatprovides libstdc++.so.6报以下内容接着第2步：
Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile libstdc++4.8.5-39.el7.i686 : GUN Standard C++ Library Repo : base Matched from: Provides : libstdc++.so.6
2.安装libstdc++-4.8.5-39.el7.i686
yum install libstdc++-4.8.5-39.el7.i686报以下错误内容接着第3步：
Loaded plugins: fastestmirror

--> Finished Dependency Resolution
Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:
1. You have an upgrade for libstdc++ which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libstdc++ of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libstdc++.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libstdc++ installed, but
yum can only see an upgrade for one of those architectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.
3. You have duplicate versions of libstdc++ installed already.
You can use "yum check" to get yum show these errors.
...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).
Protected multilib versions: libstdc++-4.8.5-39.el7.i686 != libstdc++-4.8.5-36.el7_6.2.x86_64问题的关键出现在最后一句：Protected multilib versions: libstdc++-4.8.5-39.el7.i686 != libstdc++-4.8.5-36.el7_6.2.x86_64应该是版本库不一致吧，先更新一下64位的库，执行第3步
3.更新libstdc++-4.8.5-36.el7_6.2.x86_64
yum update libstdc++-4.8.5-36.el7_6.2.x86_64更新完毕后，执行第4步
4.安装libstdc++.i686
yum install libstdc++.i6864.手动启动
进入bin目录：
sh ./startup.sh -m standalone #单机部署5.开机自启动
1.进入init.d目录
cd /etc/init.d2.创建服务文件
vim nacos3.编写脚本
脚本解释：
#chkconfig: 2345 63 37：
2345表示系统运行级别是2，3，4或者5时都启动此服务，20，是启动的优先级，80是关闭的优先级，如果启动优先级配置的数太小时如0时，则有可能启动不成功，因为此时可能其依赖的网络服务还没有启动，从而导致自启动失败。
脚本：
#!/bin/bash
#chkconfig: 2345 63 37
#description: nacos service
#processname: nacos-1.1.4
export JAVA_HOME=/usr/local/java/jdk1.8.0_333

chmod 777 nacos5.添加或删除服务
添加：
chkconfig --add nacos删除：
chkconfig --del nacos6.启动、停止或重启服务
启动：
service nacos start停止：
service nacos stop重启：
service nacos restart7.设置开启或关闭开机启动
开启：
chkconfig nacos on关闭：
chkconfig nacos off8.查看es进程，验证是否已启动
