HGDB修改端口号指导手册 1、文档用途 本文档为HGDB端口号修改指导手册。
2、详细信息 HGDB修改访问端口号:
(1) 查看当前使用的端口号 查询HGDB的pid
[highgo@pgstandby ~]$ ps -ef|grep pos root 17398 7579 0 14:10 pts/0 00:00:00 su - postgres postgres 17399 17398 0 14:10 pts/0 00:00:00 -bash highgo 37483 1 43 16:45 pts/0 00:00:01 /opt/HighGo4.3.4.8-see/bin/postgres highgo 37485 37483 0 16:45 ? 00:00:00 postgres: logger process highgo 37489 37483 0 16:45 ? 00:00:00 postgres: checkpointer process highgo 37490 37483 0 16:45 ? 00:00:00 postgres: writer process highgo 37491 37483 0 16:45 ? 00:00:00 postgres: wal writer process highgo 37492 37483 1 16:45 ? 00:00:00 postgres: autovacuum launcher process highgo 37493 37483 0 16:45 ? 00:00:00 postgres: archiver process highgo 37494 37483 0 16:45 ? 00:00:00 postgres: stats collector process highgo 37495 37483 0 16:45 ? 00:00:00 postgres: bgworker: logical replication launcher highgo 37499 37439 0 16:45 pts/0 00:00:00 grep --color=auto pos
通过pid查询端口号
[highgo@pgstandby ~]$ netstat -antup |grep 37483 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 0.0.0.0:5866 0.0.0.0:* LISTEN 37483/postgres tcp6 0 0 :::5866 :::* LISTEN 37483/postgres
(2)端口修改 检查端口是否被占用
[root@pgstandby1 bin]# lsof -i:5866 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME postgres 10668 highgo 3u IPv4 1345178 0t0 TCP *:5866 (LISTEN) postgres 10668 highgo 4u IPv6 1345179 0t0 TCP *:5866 (LISTEN)
寻找到一个未被占用的端口,然后进行修改,保存退出
vi $PGDATA/postgresql.auto.conf port=5700
重启数据库
(3)检查端口号是否修改成功 使用上述方式查看或登录数据库进行查询 根据实际情况判断是否将端口号添加到防火墙中,如防火墙已关闭,则无需添加 中标麒麟等centos系列:
firewall-cmd --permanent --add-port=5899/tcp firewall-cmd --add-port=5899/tcp
银河麒麟v4等ubuntu系列:
iptables -A INPUT -p tcp --dport 5899 -j ACCEPT iptables -A OUTPUT -p tcp --sport 5899 -j ACCEPT
详询操作系统厂商。
验证命令:
firewall-cmd --list-ports
注意:
除此之外,在HGDB的一些数据库脚本,配置文件中也包含有端口信息,如下:
例如:runpsql文件,依据操作系统类型的不同而不同,
对于Windows操作系统来说,以瀚高数据库企业版V5.6.5来举例,该文件是指D:\highgo\database\5.6.5\bin\runpsql.bat
REM Run psql :psqlcmd psql.exe -h localhost -U "highgo" -d highgo -p 5866
对于Linux操作系统来说,以瀚高数据库安全版V4.3.4.8来举例,该文件是指/opt/HighGo4.3.4.8-see/bin/runpsql.sh
[highgo@pgstandby bin]$ grep 5866 ./* Binary file ./pgauditreader matches Binary file ./pg_config matches Binary file ./postgres matches Binary file ./postmaster matches Binary file ./psql matches ./runipsql.sh:echo -n "Port [5866]: " ./runipsql.sh: HGDBPORT="5866" ./runpsql.sh:LD_LIBRARY_PATH=/opt/HighGo4.3.4.8-see/lib:$LD_LIBRARY_PATH /opt/HighGo4.3.4.8-see/bin/psql -h localhost -p 5866 -U sysdba highgo
在其它脚本,例如runipsql.sh,配置文件,例如hg_repmgr.conf等地方也有可能包含实际端口号
请修改端口时,考虑到修改需使用的脚本和配置文件的端口
