mysql是一个开放源码的小型关联式数据库管理系统，目前mysql被广泛地应用在internet上的中小型网站中。由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点，许多中小型网站为了降低网站总体拥有成本而选择了mysql作为网站数据库。
环境
FreeBSD 13-RELEASE
修改pkg源
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/reposroot@freebsd:~ # vi /usr/local/etc/pkg/repos/FreeBSD.confFreeBSD: { 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 -fUpdating 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.
安装MySQL数据库
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
运行MySQL
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=yesmysql_enable: -> yes
启动mysql服务：
root@freebsd:~ # service mysql-server startStarting mysql.
查看服务状态和mysql监听的端口：
root@freebsd:~ # service mysql-server statusmysql is running as pid 2194. root@freebsd:~ # sockstat -4lUSER 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 *:*
验证安装
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 versionEnter password: mysqladmin Ver 8.0.25 for FreeBSD13.0 on amd64 (Source distribution) Copyright (c) 2000, 2021, Oracle and/or its affiliates.
