1.6 mysql下载

?

1 2	https://dev.mysql.com/downloads/mysql/ md5: 0bdd171cb8464ba32f65f7bf58bc9533

二、 yum安装及配置

2.1 挂载本地光盘镜像

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

[root@rhel76 ~]# mkdir -p /mnt/dvd/   [root@rhel76 ~]# df -th filesystem            type      size  used avail use% mounted on /dev/mapper/rhel-root xfs        32g  4.7g   27g  15% / devtmpfs              devtmpfs  2.1g     0  2.1g   0% /dev tmpfs                 tmpfs     2.1g     0  2.1g   0% /dev/shm tmpfs                 tmpfs     2.1g   14m  2.1g   1% /run tmpfs                 tmpfs     2.1g     0  2.1g   0% /sys/fs/cgroup /dev/sda1             xfs       996m  172m  825m  18% /boot /dev/mapper/rhel-u01  xfs        30g   34m   30g   1% /u01 tmpfs                 tmpfs     413m   21k  413m   1% /run/ user /0 tmpfs                 tmpfs     413m   13k  413m   1% /run/ user /42 /dev/sr0              iso9660   4.5g  4.5g     0 100% /run/media/root/rhel-7.6 server.x86_64   [root@rhel76 ~]# mount /dev/sr0 /mnt/dvd mount: /dev/sr0 is write-protected, mounting read - only you have mail in /var/spool/mail/root

2.2 配置yum源

?

1 2 3 4 5 6 7

[root@rhel76 ~]# cd /etc/yum.repos.d/ [root@rhel76 yum.repos.d]# cat >> /etc/yum.repos.d/redhat.repo << "eof" > [rhel7] > name =jeames repo > baseurl=file:///mnt/dvd/ > gpgcheck=0 > eof

2.3 安装依赖包

?

1 2 3 4 5 6 7 8 9 10 11

[root@rhel76 ~]# yum -y groupinstall "development tools" loaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-manager this system is not registered with an entitlement server. you can use subscription-manager to register. there is no installed groups file. maybe run: yum groups mark convert (see man yum) loading mirror speeds from cached hostfile warning: group development does not have any packages to install. maybe run: yum groups mark install (see man yum) no packages in any requested group available to install or update   [root@rhel76 ~]# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make

三、卸载mariadb

?

1 2 3 4

[root@rhel76 ~]# rpm -qa |grep mariadb mariadb-libs-5.5.60-1.el7_5.x86_64   [root@rhel76 ~]# rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64

四、安装 mysql

4.1 用户及目录创建

?

1

注：可以部署多个实例，通过端口区分root 用户操作：mkdir -p /mysql/data/mysql3306mkdir -p /mysql/app/mkdir -p /mysql/conf/mkdir -p /mysql/data/mysql3306/pid/mkdir -p /mysql/data/mysql3306/socket/mkdir -p /mysql/data/mysql3306/log/mkdir -p /mysql/data/mysql3306/binlog/mkdir -p /mysql/data/mysql3306/errlogmkdir -p /mysql/data/mysql3306/relaylog/mkdir -p /mysql/data/mysql3306/slowlog/mkdir -p /mysql/data/mysql3306/tmp/

4.2 用户及组

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[root@rhel76 ~]# groupadd mysql [root@rhel76 ~]# useradd -g mysql mysql [root@rhel76 ~]# chown -r mysql:mysql /mysql [root@rhel76 ~]# passwd mysql changing password for user mysql. new password : bad password : the password is shorter than 8 characters retype new password : passwd: all authentication tokens updated successfully.   [root@rhel76 ~]# cat /etc/ group | grep mysql mysql:x:1001: [root@rhel76 ~]# cat /etc/passwd | grep mysql mysql:x:1001:1001::/home/mysql:/bin/bash

4.3 上传软件包并解压

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

[root@rhel76 ~]# cp mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz /mysql/app [root@rhel76 ~]# chown -r mysql:mysql /mysql   mysql用户操作 [root@rhel76 ~]# su - mysql md5 值验证，保证下载到的软件包无破损无木马 [mysql@rhel76 ~]$ cd /mysql/app [mysql@rhel76 app]$ ll total 1168588 -rw-r --r-- 1 mysql mysql 1196633756 nov 24 00:49 mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz [mysql@rhel76 app]$ md5sum mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz 0bdd171cb8464ba32f65f7bf58bc9533  mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz   解压软件包并重命名 [mysql@rhel76 app]$ tar xvf mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz [mysql@rhel76 app]$ mv mysql-8.0.27-linux-glibc2.12-x86_64 mysql8.0.27   [mysql@rhel76 app]$ ll total 1168588 drwxrwxr-x 9 mysql mysql        129 nov 24 00:54 mysql8.0.27 -rw-r --r-- 1 mysql mysql 1196633756 nov 24 00:49 mysql-8.0.27-linux-glibc2.12-x86_64.tar.xz

五.环境变量配置

?

1 2 3 4 5 6 7 8

cat >> /home/mysql/.bash_profile << "eof" mysql_home=/mysql/app/mysql8.0.27 path=$path:$home/. local /bin:$home/bin:$mysql_home/bin eof     source ~/.bash_profile which mysql

六.创建参数文件

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42

由于是二进制文件安装，数据库参数文件需要自己配置   cat >> /mysql/conf/my3306.cnf << "eof" [mysqld] server_id = 80273306 default -storage-engine= innodb basedir=/mysql/app/mysql8.0.27 datadir=/mysql/data/mysql3306/data/ socket=/mysql/data/mysql3306/socket/mysql.sock log-error=/mysql/data/mysql3306/log/mysqld.log pid-file=/mysql/data/mysql3306/pid/mysqld.pid port=3306 default -time_zone= '+8:00' default_authentication_plugin=mysql_native_password # 加此参数可远程登陆 transaction_isolation= read - committed max_connections=1500 back_log=500 wait_timeout=1800 max_user_connections=800 innodb_buffer_pool_size=1024m innodb_log_file_size=512m innodb_log_buffer_size=40m slow_query_log= on long_query_time=5 # log settings # slow_query_log = on slow_query_log_file = /mysql/data/mysql3306/slowlog/slow3306.log log_error = /mysql/data/mysql3306/errlog/err3306.log log_error_verbosity = 3 log_bin = /mysql/data/mysql3306/binlog/mysql_bin log_bin_index = /mysql/data/mysql3306/binlog/mysql_binlog. index general_log_file = /data/mysql/mysql3306/generallog/general.log log_queries_not_using_indexes = 1 log_slow_admin_statements = 1 expire_logs_days = 90 binlog_expire_logs_seconds = 2592000      #30d long_query_time = 2 min_examined_row_limit = 100 log_throttle_queries_not_using_indexes = 1000 innodb_flush_log_at_trx_commit=1   eof

七.数据库初始化

?

1 2 3

mysql用户操作： mysqld --defaults-file=/mysql/conf/my3306.cnf --initialize --user=mysql --basedir=/mysql/app/mysql8.0.27 --datadir=/mysql/data/mysql3306/data/ 注意：以上同一行执行

八.启动mysql

?

1 2 3 4

[mysql@rhel76 ~]$ mysqld_safe --defaults-file=/mysql/conf/my3306.cnf --user=mysql & [1] 21406 [mysql@rhel76 ~]$ 2021-11-24t06:14:23.240372z mysqld_safe logging to '/mysql/data/mysql3306/errlog/err3306.log' . 2021-11-24t06:14:23.296992z mysqld_safe starting mysqld daemon with databases from /mysql/data/mysql3306/data

九.登陆mysql

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

第一次登录 mysql 时，需要到错误日志下找初始化密码，我这里的密码为：-(qy5aj9t,=a 使用 socket 加密码登录进去后，无法查询任何东西，提示先要修改 root 密码。   [mysql@rhel76 ~]$ cat /mysql/data/mysql3306/errlog/err3306.log | grep password   2021-11-24t06:12:14.610657z 0 [note] [my-010309] [server] auto generated rsa key files through --sha256_password_auto_generate_rsa_keys are placed in data directory. 2021-11-24t06:12:14.610686z 0 [note] [my-010308] [server] skipping generation of rsa key pair through --caching_sha2_password_auto_generate_rsa_keys as key files are present in data directory. 2021-11-24t06:12:14.615367z 6 [note] [my-010454] [server] a temporary password is generated for root@localhost: -(qy5aj9t,=a 2021-11-24t06:14:26.153958z 0 [note] [my-010308] [server] skipping generation of rsa key pair through --sha256_password_auto_generate_rsa_keys as key files are present in data directory. 2021-11-24t06:14:26.153979z 0 [note] [my-010308] [server] skipping generation of rsa key pair through --caching_sha2_password_auto_generate_rsa_keys as key files are present in data directory.   [mysql@rhel76 ~]$ mysql -uroot -p enter password : error 2002 (hy000): can 't connect to local mysql server through socket ' /tmp/mysql.sock ' (2)   ##此处通过sock登陆 [mysql@rhel76 ~]$ mysql -uroot -p  -p 3306 -s /mysql/data/mysql3306/socket/mysql.sock enter password: welcome to the mysql monitor.  commands end with ; or \g. your mysql connection id is 8 server version: 8.0.27     copyright (c) 2000, 2021, oracle and/or its affiliates.     oracle is a registered trademark of oracle corporation and/or its affiliates. other names may be trademarks of their respective owners.     type ' help; ' or ' \h ' for help. type ' \c' to clear the current input statement.     mysql> status error 1820 (hy000): you must reset your password using alter user statement before executing this statement.

十.修改密码

?

1

mysql> alter user root@ 'localhost' identified by 'root' ;query ok, 0 rows affected (0.01 sec)mysql> status --------------mysql  ver 8.0.27 for linux on x86_64 (mysql community server - gpl)connection id:          8current database:current user:           root@localhostssl:                    not in usecurrent pager:          stdoutusing outfile:          ''using delimiter:        ;server version:         8.0.27protocol version:       10connection:             localhost via unix socketserver characterset:    utf8mb4db     characterset:    utf8mb4client characterset:    utf8mb4conn.  characterset:    utf8mb4unix socket:            /mysql/data/mysql3306/socket/mysql.sockbinary data as:         hexadecimaluptime:                 8 min 0 secthreads: 2  questions: 7  slow queries: 0  opens: 398  flush tables: 3  open tables: 36  queries per second avg: 0.014--------------

十一.远程登陆设置

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

使用如下语句创建 root 用户是无法通过 navicat 等客户端登录的， 由于从 mysql8 开始，身份验证插件发生改变， 默认的 “caching_sha2_password” 不允许远程登录， 故需将此插件修改为 “mysql_native_password” 便可登录。   mysql> create user root@ '%' identified with mysql_native_password by 'root' ; mysql> grant all on *.* to root@ '%' with grant option ; mysql> flush privileges ;   mysql> select user ,host,plugin from mysql. user ;  + ------------------+-----------+-----------------------+ | user             | host      | plugin                | + ------------------+-----------+-----------------------+ | root             | %         | mysql_native_password | | mysql.infoschema | localhost | caching_sha2_password | | mysql.session    | localhost | caching_sha2_password | | mysql.sys        | localhost | caching_sha2_password | | root             | localhost | mysql_native_password | + ------------------+-----------+-----------------------+ 5 rows in set (0.00 sec)
