FreeBSD 13-RELEASE

需要先创建 /usr/local/etc/pkg/repos 目录，然后创建 FreeBSD.conf 配置文件，并将默认源关闭，然后添加国内软件源。

root@freebsd:~ # mkdir -p /usr/local/etc/pkg/repos
root@freebsd:~ # vi /usr/local/etc/pkg/repos/FreeBSD.conf

FreeBSD: {enabled: no}
ustc: {url: "pkg+http://mirrors.ustc.edu.cn/freebsd-pkg//${ABI}/quarterly",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkg",
  enabled: yes
}

更新 pkg 源：

root@freebsd:~ # pkg update -f
Updating ustc repository catalogue...
Fetching meta.txz: 100%    916 B   0.9kB/s    00:01    
Fetching packagesite.txz: 100%    6 MiB   6.5MB/s    00:01    
Processing entries: 100%
ustc repository update completed. 30371 packages processed.
All repositories are up to date.

搜索一下 pkg 源里面有哪些版本的 mysql：

root@freebsd:~ # pkg search "^mysql"

下面安装 mysql80 版本：

root@freebsd:~ # pkg install -y mysql80-server mysql80-client

接下来你将运行下面的命令，这会将 MySQL 服务添加到 /etc/rc.conf配置文件中，并开机启动 mysql。

root@freebsd:~ # sysrc mysql_enable=yes
mysql_enable:  -> yes

启动 mysql 服务：

root@freebsd:~ # service mysql-server start
Starting mysql.

查看服务状态和 mysql 监听的端口：

root@freebsd:~ # service mysql-server status
mysql is running as pid 2194.
root@freebsd:~ # sockstat -4l
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS      
mysql    mysqld     2194  19 tcp46  *:33060               *:*
mysql    mysqld     2194  24 tcp4   127.0.0.1:3306        *:*
root     sshd       802   4  tcp4   *:22                  *:*
root     sendmail   781   3  tcp4   127.0.0.1:25          *:*
root     syslogd    709   7  udp4   *:514                 *:*

要验证安装，您可以用 root 身份登录并使用以下命令检查数据库版本：

root@freebsd:~ # mysqladmin -u root -p version
