声明： 这篇博客用来记录自己初学Nacos集群配置的过程，踩过一些坑，希望对大家有所帮助！
Software Environment:
- Linux virtual machine: CentOS 6.5
- JDK1.8 installation package, mysql 5.7 installation package, nginx installation package, nacos 1.1.4 installation package (here are all linux installation packages)
Installation process
Upload the installation package to linux through tools
What I use here: WinSCP tool
JDK 1.8 installation
JDK installation, I will not go into details here, it is too simple, Baidu has a lot!
General steps:
- Unzip
- Move the decompressed file to the directory you want to put
- Configure environment variables in /etc/profile system environment variables
Nginx installation
This can refer to the rookie tutorial, very detailed: https://www.runoob.com/linux/nginx-install-setup.html
Configure proxy nacos cluster
upstream cluster{
server 127.0.0.1:3333;
server 127.0.0.1:4444;
server 127.0.0.1:5555;
}
server {
listen 1111;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
#root html;
#index index.html index.htm;
proxy_pass http://cluster;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

mysql 5.7 installation
I have to talk about this. At first, I thought it was the same as the mysql 5.6 installation tutorial. The result was a problem when I tried it. There are a lot of Baidus, and I usually report an error when I do it.
Installation package download address: http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz
General steps
注意：一下命令只是演示，里面出现的文件名，根据你的具体情况而定， 还要注意执行这些命令时在拿个路径下
# 解压
# 我的压缩包都上传到 /usr/local/temp
# 当前路径：/usr/local/temp
tar -zxvf mysql-5.7.17-linux-glibc2.12-x86_64.tar.gz
# 移动mysql到想放的目录，当然不移动也可以
# 当前路径：/usr/local/temp
mv mysql-5.7.17-linux-glibc2.12-x86_64 /usr/local/mysql
# 切换路径到mysql目录中
cd /usr/local/mysql
# 创建mysql用户和用户组
[root@localhost /]# groupadd mysql
[root@localhost /]# useradd -r -g mysql mysql
# 创建data目录
mkdir /usr/local/mysql/data
# 初始化数据库
[root@localhost /]# cd /usr/local/mysql/bin
[root@localhost bin]# ./mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql
After running the initialization command successfully, the output log is as follows:
temporarily save the circled string, which is the temporary login password of the mysql administrator!
Edit the configuration file my.cnf and add the configuration as follows
# 编辑
[root@localhost bin]# vim /etc/my.cnf
# 配置内容
[mysqld]
datadir=/usr/local/mysql/data
port=3306
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
symbolic-links=0
max_connections=600
innodb_file_per_table=1
lower_case_table_names=1
Start the test
/usr/local/mysql/support-files/mysql.server start
Add soft connection and restart mysql service
[root@localhost /]# ln -s /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@localhost /]# ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
[root@localhost /]# service mysql restart
Log in to mysql and change the password (the password is the temporary password generated in step 5)
[root@localhost /]# mysql -u root -p
Enter password:
mysql>set password for root@localhost = password('yourpass');
Open remote connection
mysql>use mysql;
msyql>update user set user.Host='%' where user.User='root';
mysql>flush privileges;
Set automatic startup
# 将服务文件拷贝到init.d下，并重命名为mysql
[root@localhost /]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
# 赋予可执行权限
[root@localhost /]# chmod +x /etc/init.d/mysqld
# 添加服务
[root@localhost /]# chkconfig --add mysqld
At this point, the mysql database installation has been completed.
Prepare the data and data sheet needed by Naocs
Here is a bit simpler, use the windows database connection tool to connect, create: nacos_config database, and then execute the nacos-mysql.sql file under the conf under the nacos installation package.
Navicat I use here:
Finally, run sql (this is also available under the Linux installation package):
Installation and configuration of Naocs
# 解压、将解压后的文件copy到 /usr/local/nacos
tar -zxvf nacos-server-1.1.4.tar.gz
mv nacos-server-1.1.4.tar.gz /usr/local/nacos
# 需要修改三个文件
## 第一个：cluster.conf
cd /usr/local/nacos/conf
cp cluster.conf.example cluster.conf
vim cluster.conf
# 将之前的内容全部删除，配置如下，ip为你自己虚拟机的ip
192.168.75.141:3333
192.168.75.141:4444
192.168.75.141:5555
## 第二个，修改application.properties
vim application.properties
# 在最下面加上如下配置
nacos.istio.mcp.server.enabled=false
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=121891
# 注意这里的密码
## 第三个文件
cd /usr/local/nacos/bin
vim startup.sh
# 找到如下配置修改和我一样
while getopts ":m:f:s:p:" opt
do
case $opt in
m)
MODE=$OPTARG;;
f)
FUNCTION_MODE=$OPTARG;;
s)
SERVER=$OPTARG;;
p)
PORT=$OPTARG;;
?)
echo "Unknown parameter"
exit 1;;
esac
done
## 最下面
# start
echo "$JAVA ${JAVA_OPT}" > ${BASE_DIR}/logs/start.out 2>&1 &
nohup $JAVA -Dserver.port=${PORT} ${JAVA_OPT} nacos.nacos >> ${BASE_DIR}/logs/start.out 2>&1 &
echo "nacos is starting，you can check the ${BASE_DIR}/logs/start.out"
## 还有一个地方就是一个坑，本来到这里配置已经完成，但你启动的时候可能有些节点用不了，原因就是配置的java启动参数太大
## 找到如下配置，修改和我一样
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
This configuration is complete
start up
# 启动nginx
# 启动mysql
# 启动nacos
cd /usr/local/nacos/bin
./startup.sh -p 3333
./startup.sh -p 4444
./startup.sh -p 5555
## 验证
ps -ef|grep nacos|grep -v grep|wc -l
# 如果结果为3这证明启动成功
Three places where the third file is modified:
Finally,
visit on the windows side : 192.168.75.141:1111/nacos
If successful, the login interface of nacos will be displayed
