绝地灬酷狼 2023-07-18 02:28 20阅读 0赞

1、下载软件安装包  
mysql-5.7.11-linux-glibc2.5-x86\_64.tar.gz  
2、创建mysql用户  
useradd mysql  
passwd mysql\_123456  
创建用户使其不允许登录：  
请注意要在root用户下进行  
修改已经存在的用户使其不允许登录：  
usermod -s /sbin/nologin  
新建用户不允许登录：  
useradd -s /sbin/nologin

3、创建mysql5.7版本需要的目录  
mkdir -pv /data/mysql/mysql9571/\{conf,data,logs,run,tmp\}

4、创建MySQL5.7需要的配置文件  
\[root@iZm5eckxl2tqyk76wy33pkZ ~\]\# cd /data/mysql/mysql9571/conf/  
\[root@iZm5eckxl2tqyk76wy33pkZ conf\]\# more my9571.cnf  
\[client\]  
default-character-set=utf8  
port = 9571  
socket = /data/mysql/mysql9571/run/mysql9571.sock  
\[mysqld\]  
user = mysql  
port = 9571  
character\_set\_server=utf8  
init\_connect=‘SET NAMES utf8’  
socket = /data/mysql/mysql9571/run/mysql9571.sock  
basedir = /opt/mysql-5.7.11-linux-glibc2.5-x86\_64/  
datadir = /data/mysql/mysql9571/data  
log-error = /data/mysql/mysql9571/data/error.log  
pid-file = /data/mysql/mysql9571/run/mysql9571.pid  
tmpdir = /data/mysql/mysql9571/tmp  
slow-query-log-file = /data/mysql/mysql9571/data/9571slow.log  
log-bin = mysql-bin  
binlog\_format = row  
server-id = 111  
binlog-ignore-db = information\_schema  
binlog-ignore-db = cluster  
binlog-ignore-db = mysql  
binlog-do-db=test  
\[root@iZm5eckxl2tqyk76wy33pkZ conf\]\#  
解压mysql二进制包  
\[root@VM\_0\_8\_centos opt\]\# tar -zxvf mysql-5.7.11-linux-glibc2.5-x86\_64.tar.gz  
修改目录权限  
chown -R mysql.mysql /opt/mysql-5.7.11-linux-glibc2.5-x86\_64/  
chown -R mysql.mysql /data/mysql/mysql9571/  
配置环境变量  
echo ‘export PATH=/opt/mysql-5.7.11-linux-glibc2.5-x86\_64/bin:$PATH’ >> /etc/profile  
source /etc/profile

5、初始化mysql5.7版本数据库  
\[root@iZm5eckxl2tqyk76wy33pkZ conf\]\# cd /opt/mysql-5.7.11-linux-glibc2.5-x86\_64/  
\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# ./bin/mysqld --initialize-insecure --user=mysql --basedir=/opt/mysql-5.7.11-linux-glibc2.5-x86\_64 --datadir=/data/mysql/mysql9571/data/  
2018-05-26T13:28:52.343461Z 0 \[Warning\] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit\_defaults\_for\_timestamp server option (see documentation for more details).  
2018-05-26T13:28:53.463429Z 0 \[Warning\] InnoDB: New log files created, LSN=45790  
2018-05-26T13:28:53.666121Z 0 \[Warning\] InnoDB: Creating foreign key constraint system tables.  
2018-05-26T13:28:53.738045Z 0 \[Warning\] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: bbfcb5fa-60e8-11e8-bac6-00163e05510e.  
2018-05-26T13:28:53.757450Z 0 \[Warning\] Gtid table is not ready to be used. Table ‘mysql.gtid\_executed’ cannot be opened.  
2018-05-26T13:28:53.757951Z 1 \[Warning\] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.  
\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# cd ~  
查看my9571.cnf的权限

\[root@ttlsa ~\]\# ls -l my9571.cnf  
\-rwxrwxrwx 1 root root 4878 Jul 30 11:31 my9571.cnf  
权限777，任何一个用户都可以改my9571.cnf，存在很大的安全隐患.  
修复MySQL问题  
\[root@VM\_0\_8\_centos conf\]\# chmod 644 my9571.cnf

6、启动mysql5.7版本数据库  
\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# ./bin/mysqld --defaults-file=/data/mysql/mysql9571/conf/my9571.cnf  
\[root@iZm5eckxl2tqyk76wy33pkZ conf\]\# cd /opt/mysql-5.7.11-linux-glibc2.5-x86\_64/  
注意这样不是后台进程启动，终端断开数据库会kill掉。  
停止mysql的方法  
\[root@VM\_0\_2\_centos logs\]\# mysqladmin -uroot -p shutdown -S /data/mysql/9571/run/mysql9571.sock  
Enter password:

7、登陆数据库  
\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# ./bin/mysql -S /data/mysql/mysql9571/run/mysql9571.sock

\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# netstat -nltp  
8、后台启动mysql  
\[root@iZm5eckxl2tqyk76wy33pkZ ~\]\# cd /opt/mysql-5.7.11-linux-glibc2.5-x86\_64/  
\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# ./bin/mysqld --defaults-file=/data/mysql/mysql9571/conf/my9571.cnf &

9、修改root密码  
修改后需要重启生效

\[root@iZm5eckxl2tqyk76wy33pkZ mysql-5.7.11-linux-glibc2.5-x86\_64\]\# ./bin/mysql -S /data/mysql/mysql9571/run/mysql9571.sock
