搭建环境时遇到问题

kingbase
#查看数据相关服务运行状态
systemctl status kingbase8d.service
连接kingbase库
ksql -p54321 -Usa -dtest
创建库
create database db_zhba
\c db_zhba
\i
kingbase启动
root.sh[./sys_ctl -D /home/kingbase/KingbaseES/data start]
kingbase关闭
./sys_ctl -D /home/kingbase/KingbaseES/data stop
遇到问题：
1、在kingbase用户下执行sys_ctl -D data start时报错
./sys_ctl -D /home/kingbase/KingbaseES/data start
等待服务器进程启动 …致命错误: XX000: License file should have write access mode in floating mode, or use license generating date as base date.
位置: PostmasterMain, postmaster.c:650
已停止等待
sys_ctl: 无法启动服务器进程

   原因：license.dat权限是root用户权限
   chown -R kingbase:kingbase license.dat

东方通：
1、 安装东方通rpm包
rpm -ivh TongWeb-7.0.4.1-1.nfs.x86_64.rpm
查看东方通在系统中的安装路径
rpm -ql TongWeb
2、启动东方通
startservernohup.sh
遇到问题：
1、启动失败
原因：1、未放license.dat
2、安装java版本1.8
3、登录用户
http://172.23.26.44:9060/console/rest

 东方通部署地址：http://172.23.26.164:9060/console/

rocketmq搭建：
启动服务器
systemctl start mqnamesrv.service
查看服务状态
systemctl status mqnamesrv.service
远程拷贝
scp root@172.23.26.88:/home/rocket/rocketmq-console-ng-2.0.0.jar ./

rocket安装过程中遇到问题：
[root@localhost rocketConsole]# cat nohup.out

解决方式，jdk环境版本不对，需要将linux中默认的jdk版本升级到1.8
jdk版本搭建
jdk版本默认1.7 升级为1.8
/etc/profile 中配置java环境变量
source /etc/profile 配置生效
在升级jdk过程中，两个问题

	1.没有预装jdk

	解决方法：不用管，直接进行下面的步骤

	2.更新完/etc/profile并且重新读取后还是显示1.7的java版本

	解决方法：问题原因是配置文件中的一行

	  export PATH=${JAVA_PATH}:$PATH
	之前写的方式是$PATH在前面，这样系统还是会读取前面的1.7环境变量。改成后面就可以了

nginx安装过程遇到问题

 [root@localhost software]# rpm -ivh nginx-1.19.0-thunisoft.nfs.x86_64.rpm
		错误：依赖检测失败：
				libcrypto.so.10()(64bit) 被 nginx-1.19.0-thunisoft.nfs.x86_64 需要
				libssl.so.10()(64bit) 被 nginx-1.19.0-thunisoft.nfs.x86_64 需要

解决方方式：
跳过依赖检查
rpm -ivh nginx-1.19.0-thunisoft.nfs.x86_64.rpm --nodeps --force
命令：
启动nginx
./nginx start
[root@localhost nginx-1.19.0]# ./nginx start

nginxwebUI遇到问题
    页面 配置 页面上生成conf-》目标配置文件修改为/home/nginxWebUI/nginx.conf 
	点击重新装载/启动nginx都报错
	 Cannot run program "nginx": error=2, No such file or directory
	 
	
报错：
   内部执行命令： /opt/nginx-1.19.0/nginx -s reload -c /home/nginxWebUI/nginx.conf
    由于nginxwebui中不支持 -s参数配置 ，需手动  /opt/nginx-1.19.0/nginx reload -c /home/nginxWebUI/nginx.conf 
  
  解决方案：页面上生成conf-》目标配置文件修改为 /opt/nginx-1.19.0/conf/nginx.conf 
  手动执行命令 /opt/nginx-1.19.0/nginx   reload

东方通启动报错：

检查external.vmoptions的java_home的配置

 [root@localhost bin]# tail -f external.vmoptions
-DdisableVerCode=true
-DLoadClassCache.Disabled=true
-DuseBeanManagerInCompJNDI=false
-DjvProfile=true

minio 多节点安装部署—run.sh 脚本启动minio【可参考https://www.yepk.cn/archives/minio-cluster.html】
minio server 启动生成的节点data 【多节点时 http:ip地址+minio安装地址绝对路径，此处为四个节点】

#!/bin/bash
export MINIO_ACCESS_KEY=minio
export MINIO_SECRET_KEY=123qwe!@#
nohup /usr/local/minio/bin/minio server http://172.23.26.44/usr/local/minio/data1 http://172.23.26.44/usr/local/minio/data2
http://172.23.26.44/usr/local/minio/data3 http://172.23.26.44/usr/local/minio/data4 >/usr/local/minio/log/running.log 2>&1 &

启动报错：
Invalid command line：arguments invalid total number of endpoints for erasure mode.
please provide an even number of endpoints greater of equal to 4
因为我开始搭的是两个节点【就是上面参数路径多少个就是几个节点】，所以导致需要我们必须搭四台以上才行，

修改kingbase用户密码 alter user sa with password 'tusc@6789#JKL'


sudo systemctl stop firewalld.service 关闭防火墙

原来，在客户端访问PostgreSQL数据库时，PostgreSQL会读取文件pg_hba.conf判断是否信任该主机，故所有需要连接PostgreSQL Server的主机都应当在pg_hba.conf中添加对其信任，即使是Server主机也不例外！
