[[email protected] ~]# 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

2.7 创建用户

[[email protected] ~]# groupadd -g 5866 highgo [[email protected] ~]# 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.

2.8 创建相关目录

[[email protected] ~]# mkdir -p /data/highgo/4.3.2 [[email protected] ~]# mkdir -p /data/highgo/hgdbbak/archive [[email protected] ~]# chown -R highgo:highgo /data

2.9 修改内核参数

[[email protected] ~]# vi /etc/sysctl.conf

[[email protected] ~]# sysctl -p

2.10 修改用户限制

[[email protected] ~]# vi /etc/security/limits.conf
