介绍HGDB4.1.1在Redhat 7.5系统上的图形化安装流程。
详细信息
1.安装版本及注意事项
1.1 安装版本
| 操作系统 |
Redhat 7.5 x86_64 |
| HGDB |
HGDB 4.1.1 |
1.2 注意事项
使用图形化安装HGDB时，必须将系统用户切换至highgo用户执行安装，在root用户中执行su – highgo命令切换用户，安装时不能显示图形界面。
2.状态检查
2.1 检查SWAP空间
| [root@localhost ~]# grep MemTotal /proc/meminfo MemTotal: 1015508 kB [root@localhost ~]# grep SwapTotal /proc/meminfo SwapTotal: 839676 kB [root@localhost ~]# free -h total used free shared buff/cache available Mem: 991M 705M 70M 5.6M 214M 102M Swap: 819M 90M 729M |
2.2 操作系统
| [root@localhost ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.5 (Maipo) [root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-862.el7.x86_64 #1 SMP Wed Mar 21 18:14:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux |
2.3 关闭防火墙
| [root@localhost ~]# systemctl stop firewalld.service [root@localhost ~]# systemctl disable firewalld.service Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. |
2.4 关闭NetworkManager
| [root@localhost ~]# systemctl stop NetworkManager.service [root@localhost ~]# systemctl disable NetworkManager.service Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service. Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service. |
2.5 关闭selinux
| [root@localhost ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config [root@localhost ~]# setenforce 0 [root@localhost ~]# cat /etc/selinux/config | grep SELINUX # SELINUX= can take one of these three values: SELINUX=disabled # SELINUXTYPE= can take one of three two values: SELINUXTYPE=targeted |
2.6 主机名和时间检查
| [root@localhost ~]# hostnamectl status Static hostname: localhost.localdomain Icon name: computer-vm Chassis: vm Machine ID: 2bad7c3a0b264eff8f1939c33ca63a2c Boot ID: fde62257be904629b34be751afc97924 Virtualization: kvm Operating System: Red Hat Enterprise Linux Server 7.5 (Maipo) CPE OS Name: cpe:/o:redhat:enterprise_linux:7.5:GA:server Kernel: Linux 3.10.0-862.el7.x86_64 Architecture: x86-64 [root@localhost ~]# timedatectl Local time: Thu 2018-07-05 22:30:17 CST Universal time: Thu 2018-07-05 14:30:17 UTC RTC time: Thu 2018-07-05 14:30:14 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: yes RTC in local TZ: no DST active: n/a |
2.7 安装系统软件包
| [root@localhost ~]# vi /etc/yum.repos.d/highgo.repo [Server] name=Red Hat Enterprise Linux $releasever Beta - $basearch - Source baseurl=file:///media/cdrom enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release |
创建/media/cdrom目录：
| [root@localhost ~]# mkdir /media/cdrom |
挂载操作系统镜像：
| [root@localhost ~]# mount /dev/sr0 /media/cdrom |
安装系统软件包：
| [root@localhost ~]# yum install wget readline readline-devel zlib zlib-devel openssl openssl-devel pam-devel libxml2-devel libxslt-devel python-devel tcl-devel gcc gcc-c++ -y |
2.8 创建用户
| [root@localhost ~]# groupadd -g 5866 highgo [root@localhost ~]# useradd -u 5866 -g highgo highgo; echo XXXXXX（密码） | passwd -f --stdin highgo Changing password for user highgo. passwd: all authentication tokens updated successfully. |
2.9 创建相关目录
| [root@localhost ~]# mkdir -p /home/highgo/4.1.1 [root@localhost ~]# mkdir -p /home/hgdbbak/archive [root@localhost ~]# chown -R highgo:highgo /home/highgo/ [root@localhost ~]# chown -R highgo:highgo /home/hgdbbak/ |
2.10 修改内核参数
| [root@localhost ~]# vi /etc/sysctl.conf |
添加以下内容：
| #for highgo db 4.1.1 kernel.shmmni = 4096 kernel.sem = 4096 2147483647 2147483646 512000 fs.file-max = 7672460 net.ipv4.ip_local_port_range = 9000 65000 net.core.rmem_default = 1048576 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_max_syn_backlog = 4096 net.core.netdev_max_backlog = 10000 vm.overcommit_memory = 0 fs.aio-max-nr = 1048576 net.ipv4.tcp_timestamps = 0 |
root用户运行如下命令是参数立即生效：
| [root@localhost ~]# sysctl -p |
2.11 修改用户限制
| [root@localhost ~]# vi /etc/security/limits.conf |
添加如下内容：
| #for highgo db 4.1.1 highgo soft core unlimited highgo hard nproc unlimited highgo soft nproc unlimited highgo hard memlock unlimited highgo hard nofile 1024000 highgo soft memlock unlimited highgo soft nofile 1024000 |
