1.3 系统配置
1.3.1 操作系统

[root@localhost ~]# cat /etc/redhat-release

CentOS Linux release 7.3.1611 (Core)

1.3.2 关闭防火墙

[root@localhost data]# systemctl disable firewalld.service

[root@localhost data]# systemctl stop firewalld.service

1.3.3 关闭NetworkManager

[root@localhost data]# systemctl stop NetworkManager.service

[root@localhost data]# systemctl disable NetworkManager.service

1.3.4 关闭selinux

[root@localhost upload]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

[root@localhost upload]# 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

1.3.7 创建用户

[root@localhost data]# groupadd -g 5866 highgo

[root@localhost data]# useradd -u 5866 -g highgo highgo; echo xxx（敏感信息） | passwd -f --stdin highgo

[root@localhost upload]# mkdir -p /data/highgo/4.3.2

[root@localhost upload]# mkdir -p /data/hgdbbak/archive

[root@localhost upload]# chown -R highgo:highgo /data

vm.dirty_background_bytes = 409600000

net.ipv4.tcp_max_tw_buckets = 262144

1.3.10 修改用户限制

[root@localhost upload]# vi /etc/security/limits.conf

#for highgo db 4.3.2

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

1.3.11 用户环境变量配置

[root@localhost upload]# vi /home/highgo/.bash_profile

export
