Ensure Symbolic Links are Disabled

中级别 1自动化mysql

说明

The symbolic-links and skip-symbolic-links options for MySQL determine whether symbolic link support is available. When use of symbolic links is enabled, they have different effects depending on the host platform. When symbolic links are disabled, then symbolic links stored in files or entries in tables are not used by the database. Runs mysql -NBe with the client defaults: put an administrative account in ~/.my.cnf (mode 0600) or a mysql_config_editor login path, not MYSQL_PWD (see 1.4/1.6).

检查方式

审计方法: SQL 查询

sql_query

out=$(mysql -NBe "SELECT IF(@@global.have_symlink = 'DISABLED', 'compliant', 'noncompliant')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

Set skip-symbolic-links=YES under [mysqld] in /etc/my.cnf (or /etc/mysql/mysql.conf.d/mysqld.cnf), then restart MySQL.
