nacos ubuntu16.04集群部署

程序员文章站 2022-06-11 16:29:02

...

请先安装好jdk1.8

安装mysql5.7

安装方法

安装nginx

程序安装 sudo apt-get install nginx
安装后可执行文件路径/usr/sbin/nginx 此时在任意路径下输入nginx都可以启动
查看nginx是否在执行 ps -ef|grep nginx
nginx命令

nginx -s stop 停止运行
nginx -s reload 重新加载配置文件,慎用，有概率不生效，建议老老实实重启

配置文件更改，ubuntu下的配置文件有两个路径
/etc/nginx/nginx.conf 文件内容如下

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
	worker_connections 768;
	# multi_accept on;
}

http {

	##
	# Basic Settings
	##

	sendfile on;
	tcp_nopush on;
	tcp_nodelay on;
	keepalive_timeout 65;
	types_hash_max_size 2048;
	# server_tokens off;

	# server_names_hash_bucket_size 64;
	# server_name_in_redirect off;

	include /etc/nginx/mime.types;
	default_type application/octet-stream;

	##
	# SSL Settings
	##

	ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
	ssl_prefer_server_ciphers on;

	##
	# Logging Settings
	##

	access_log /var/log/nginx/access.log;
	error_log /var/log/nginx/error.log;

	##
	# Gzip Settings
	##

	gzip on;
	gzip_disable "msie6";

	# gzip_vary on;
	# gzip_proxied any;
	# gzip_comp_level 6;
	# gzip_buffers 16 8k;
	# gzip_http_version 1.1;
	# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

	##
	# Virtual Host Configs
	##
	#以下两条命令为加载/etc/nginx/conf.d以及/etc/nginx/sites-enabled目录下的配	  #置文件
	include /etc/nginx/conf.d/*.conf;
	include /etc/nginx/sites-enabled/*;
}


#mail {
#	# See sample authentication script at:
#	# http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
#	# auth_http localhost/auth.php;
#	# pop3_capabilities "TOP" "USER";
#	# imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
#	server {
#		listen     localhost:110;
#		protocol   pop3;
#		proxy      on;
#	}
# 
#	server {
#		listen     localhost:143;
#		protocol   imap;
#		proxy      on;
#	}
#}

/etc/nginx/sites-available/default 文件内容如下,已更改
作用为:监听本地1111端口,并将请求转发到cluster上，cluster配置了3个地址，实现负载均衡

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
##

# Default server configuration
#

upstream cluster{
	server 127.0.0.1:3333;
	server 127.0.0.1:4444;
	server 127.0.0.1:5555;
}

	server_name localhost;
	#listen [::]:80 default_server;

	# SSL configuration
	#
	# listen 443 ssl default_server;
	# listen [::]:443 ssl default_server;

	# Note: You should disable gzip for SSL traffic.
	# See: https://bugs.debian.org/773332

	# Read up on ssl_ciphers to ensure a secure configuration.
	# See: https://bugs.debian.org/765782

	location / {
		# First attempt to serve request as file, then
		# as directory, then fall back to displaying a 404.

		proxy_pass http://cluster;
	}

	# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
	#

	# deny access to .htaccess files, if Apache's document root
	# concurs with nginx's one
	#
	#location ~ /\.ht {

	#}
}


# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
#	listen 80;
#	listen [::]:80;
#
#	server_name example.com;
#
#	root /var/www/example.com;
#	index index.html;
#
#	location / {
#		try_files $uri $uri/ =404;
#	}
#}

nacos 安装，我使用的是nacos 1.1.4，版本不同对下面的步骤有影响，尤其是startup.sh

nacos github下载
可以在ubuntu中使用wget 下载地址 下载
加压下载后的gz压缩包 tar -zxvf 文件名 默认加压到当前文件夹，可以使用**-C 路径**指定解压目录
进入解压得到的nacos文件夹cd nacos
进入配置文件目录cd conf
编辑application.properties文件 在文件最后新增

##############mysql

spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=数据库用户名
db.password=数据库密码

编写cluster.conf配置文件

#当前目录还是conf
cp cluster.conf.example cluster.conf
#查询ubuntu本机ip，内网外网都可以
ifconfig
#编辑cluster.conf文件，将里面的ip和端口换成自己的，比如我的是,和nginx中配置的端口号#一致
#it is ip
#example
192.168.88.130:3333
192.168.88.130:4444
192.168.88.130:5555

更改startup.sh文件，在nacos/bin目录下
备份startup.sh文件

cp startup.sh startup.sh.back

编辑startup.sh文件,以下是我修改后的
增加-p参数设置属性，用于设置nacos运行端口号

启动nacos集群

#在bin目录下，启动三个服务，内存占用较大，可以更改startup.sh中的JAVA_OPT属性减少内
#存分配,下面三条语句请隔2分钟分别执行，如果你的ubuntu配置牛逼当我没说
bash startup.sh -p 3333
bash startup.sh -p 4444
bash startup.sh -p 5555

启动成功的输出
