MySQL5.7.20二进制包安装¶
1. 下载二进制包¶
# https://downloads.mysql.com/archives/community/
# 按下面提示输入参数，然后点击下载
#1. Product Version:5.7.20
#2. Operating System:linux-generic
#3. OS Version:64-bit
mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
2. 解压缩二进制包¶
2.1 将二进制包上传到Linux的/usr/local目录¶
[root@k8s-node1 ~]# ls /usr/local
bin etc games include lib lib64 libexec mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz sbin share src
2.2 解压缩二进制包¶
[root@k8s-node1 ~]# cd /usr/local/
[root@k8s-node1 local]# tar -zxvf mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
[root@k8s-node1 local]# ls
bin games lib libexec mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz share
etc include lib64 mysql-5.7.20-linux-glibc2.12-x86_64 sbin src
2.3 将解压缩后的目录改名¶
[root@k8s-node1 local]# mv mysql-5.7.20-linux-glibc2.12-x86_64 mysql
[root@k8s-node1 local]# ls
bin etc games include lib lib64 libexec mysql mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz sbin share src
2.4 创建mysql用户，更改权限¶
[root@k8s-node1 local]# useradd mysql
[root@k8s-node1 local]# chown -R mysql:mysql /usr/local/mysql
疑问：是不是应该创建不允许登录的用户？
useradd mysql -s /sbin/nologin -M
3. 创建数据目录¶
mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql
4. 初始化数据¶
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
得到密码
[root@k8s-node1 bin]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

5. 编写配置文件¶
vim /etc/my.cnf
[mysqld]
basedir=/usr/local/mysql
datadir=/data/mysql
socket=/tmp/mysql.sock
log_error=/var/log/mysql.log
[client]
socket=/tmp/mysql.sock
6. 启动¶
[root@k8s-node1 bin]# ./mysqld_safe &
[1] 78665
[root@k8s-node1 bin]# 2021-04-23T01:21:33.554572Z mysqld_safe Logging to '/var/log/mysql.log'.
2021-04-23T01:21:33.583723Z mysqld_safe Starting mysqld daemon with databases from /data/mysql
[root@k8s-node1 bin]# netstat -tunlp |grep 330
tcp6 0 0 :::3306 :::* LISTEN 78780/mysqld
7. 连接测试¶
[root@k8s-node1 bin]# ./mysql -uroot -p'3b%G<+#)mtfk'

8. 复制快捷管理mysql服务脚本到/etc/init.d/¶
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
stop测试
[root@k8s-node1 ~]# /etc/init.d/mysqld stop
Shutting down MySQL..2021-04-23T01:27:13.643796Z mysqld_safe mysqld from pid file /data/mysql/k8s-node1.pid ended
SUCCESS!
[1]+ Done ./mysqld_safe (wd: /usr/local/mysql/bin)
(wd now: ~)
[root@k8s-node1 ~]# netstat -tunlp|grep 330
[root@k8s-node1 ~]#
start测试
[root@k8s-node1 ~]# /etc/init.d/mysqld start

#问题：要使用快捷命令，命令必须要在: /usr/local/mysql/bin 目录下！！！
[root@151 application]# ls mysql/support-files/
magic mysqld_multi.server mysql-log-rotate mysql.server
[root@151 application]#
[root@151 application]#
[root@151 application]#
[root@151 application]# ls /etc/init.d/

Can't execute /usr/local/mysql/bin/mysqld_multi from dir /usr/local/mysql
[root@151 application]#

8. 可以添加环境变量（略）¶
echo "export /usr/local/mysql/bin:$PATH" >>/etc/profile
source /etc/profile
测试
echo $PATH
which mysql
