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: 1016476 kB [root@localhost ~]# grep SwapTotal /proc/meminfo SwapTotal: 839676 kB [root@localhost ~]# free -h total used free shared buff/cache available Mem: 992M 366M 154M 7.6M 471M 459M Swap: 819M 0B 819M |
2.2 操作系统
| [root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) [root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux |
2.3 关闭防火墙
| [root@localhost data]# systemctl disable firewalld.service [root@localhost data]# systemctl stop firewalld.service |
2.4 关闭NetworkManager
| [root@localhost data]# systemctl stop NetworkManager.service [root@localhost data]# systemctl disable NetworkManager.service |
2.5 关闭selinux
| [root@localhost data]# setenforce 0 setenforce: SELinux is disabled [root@localhost data]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config [root@localhost data]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three two values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted |
2.6 主机名和时间检查
| [root@localhost data]# hostnamectl status Static hostname: localhost.localdomain Icon name: computer-vm Chassis: vm Machine ID: fd8d3f8d3b1a4ce5b31cd84cd732b3f7 Boot ID: a91ab1617a69462b98e05a67d11e04e2 Virtualization: kvm Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 3.10.0-514.el7.x86_64 Architecture: x86-64 [root@localhost data]# timedatectl Local time: Thu 2018-06-21 15:59:01 CST Universal time: Thu 2018-06-21 07:59:01 UTC RTC time: Thu 2018-06-21 07:59:01 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: n/a |
2.7 安装系统软件包
| [root@localhost data]# 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 data]# mkdir /media/cdrom |
挂载操作系统镜像：
| [root@localhost data]# mount /dev/sr0 /media/cdrom |
安装系统软件包：
| [root@localhost data]# 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 data]# groupadd -g 5866 highgo [root@localhost data]# useradd -u 5866 -g highgo highgo; echo XXXXXX（机密信息） | passwd -f --stdin highgo |
2.9 创建相关目录
| [root@localhost data]# mkdir -p /data/highgo/4.1.1 [root@localhost data]# mkdir -p /data/hgdbbak/archive [root@localhost data]# chown -R highgo:highgo /data |
2.10 修改内核参数
| [root@localhost data]# 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 data]# sysctl -p |
2.11 修改用户限制
| [root@localhost data]# 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 |
