离线在银河麒麟高级操作系统v10安装mysql5.7
- 下载mysql5.7
MySQL :: Download MySQL Community Server (Archived Versions)
2、把下载好的包上传到服务器
3、解压
[root@1-0001 ~]# cd /data/mysql [root@1-0001 mysql]# tar -zxvf mysql-5.7.44-linux-glibc2.12-x86_64.tar.gz
4、卸载系统的mariadb数据库
查询安装的mariadb数据库
rpm -qa | grep mariadb
[root@1-0001 ~]# rpm -qa | grep mariadb mariadb-common-10.3.9-12.p01.ky10.x86_64 mariadb-10.3.9-12.p01.ky10.x86_64 mariadb-errmessage-10.3.9-12.p01.ky10.x86_64 mariadb-connector-c-3.0.6-8.ky10.x86_64 mariadb-server-10.3.9-12.p01.ky10.x86_64
5、使用命令 rpm -e --nodeps卸载
[root@1-0001 ~]# rpm -e --nodeps mariadb-common-10.3.9-12.p01.ky10.x86_64 [root@1-0001 ~]# rpm -e --nodeps mariadb-10.3.9-12.p01.ky10.x86_64 [root@1-0001 ~]# rpm -e --nodeps mariadb-errmessage-10.3.9-12.p01.ky10.x86_64 [root@1-0001 ~]# rpm -e --nodeps mariadb-connector-c-3.0.6-8.ky10.x86_64 [root@1-0001 ~]# rpm -e --nodeps mariadb-server-10.3.9-12.p01.ky10.x86_64
6、继续查询是否存在玛丽数据库rpm -qa | grep mariadb
[root@1-0001 ~]# rpm -qa | grep mariadb
7、卸载mysql数据,查询mysql
[root@1-0001 ~]# rpm -qa | grep mysql qt5-qtbase-mysql-5.11.1-13.p01.ky10.x86_64 python2-mysqlclient-1.3.12-8.ky10.x86_64
8、使用rpm -e --nodeps 卸载mysql数据库
[root@1-0001 ~]# rpm -e --nodeps qt5-qtbase-mysql-5.11.1-13.p01.ky10.x86_64 [root@1-0001 ~]# rpm -e --nodeps python2-mysqlclient-1.3.12-8.ky10.x86_64
9、在解压的mysql包中,重新命名解压文件夹为mysql-5.7.44
10、在文件夹mysql新建data、tmp和logs文件夹
11、创建用户和用户组,分配权限
# 创建一个用户组:mysql groupadd mysql # 创建一个系统用户:mysql,指定用户组为mysql useradd -r -g mysql mysql chown -R mysql:mysql /data/mysql/mysql-5.7.44/data chmod -R 750 /data/mysql/mysql-5.7.44/data chmod 777 /data/mysql/mysql-5.7.44/tmp
12、赋予mysql用户权限给mysql文件夹
chown -R mysql:mysql /data/mysql/mysql-5.7.44
13、设置配置文件mysql配置文件my.cnf(在文件夹/data/mysql/mysql-5.7.44/my.cnf)
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [mysqld] lower_case_table_names=1 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES basedir = /data/mysql/mysql-5.7.44 datadir = /data/mysql/mysql-5.7.44/data port = 3306 socket = /data/mysql/mysql-5.7.44/tmp/mysql.sock character-set-server=utf8mb4 pid-file = /data/mysql/mysql-5.7.44/data/mysqld.pid #log日志 log-error=/data/mysql/mysql-5.7.44/logs/mysql.err log_bin = /data/mysql/mysql-5.7.44/logs/mysql-bin relay_log = /data/mysql/mysql-5.7.44/logs/relay-bin slow_query_log_file = /data/mysql/mysql-5.7.44/logs/slow.log slow_query_log=on log_bin_trust_function_creators=1 #开启相关日志 general_log=OFF #设置唯一id server-id=1 #指定bin-log为row类别,其他两种是statement、mixed binlog_format=row #对指定的数据库开启bin-log,这里是对wh数据库开启bin-log服务 binlog-do-db=wh expire_logs_days = 30 #设置binlog清理时间 max_binlog_size = 1000m #binlog每个日志文件大小 binlog_cache_size = 40m #binlog缓存大小 max_binlog_cache_size = 5120m #最大binlog缓存大小
14、初始化数据库
cd /data/mysql/mysql-5.7.44/bin ./mysqld --defaults-file=/data/mysql/mysql-5.7.44/my.cnf --lower-case-table-names=1 --initialize-insecure
15、启动mysql
/data/mysql/mysql-5.7.44/bin/mysqld_safe --defaults-file=/data/mysql/mysql-5.7.44/my.cnf &
16、无密码登录mysql
/data/mysql/mysql-5.7.44/bin/mysql -S /data/mysql/mysql-5.7.44/tmp/mysql.sock -u root --skip-password
17、修改mysql密码同时允许远程访问,密码就是你设置的root登录密码
GRANT ALL ON *.* TO root@'%' IDENTIFIED BY '密码' WITH GRANT OPTION; #刷新使配置生效 flush privileges; #退出 quit
18、连接数据库
说明:
1、启动mysql
/data/mysql/mysql-5.7.44/bin/mysqld_safe --defaults-file=/data/mysql/mysql-5.7.44/my.cnf &
2、停止mysql
/data/mysql/mysql-5.7.44/bin/mysqladmin -S /data/mysql/mysql-5.7.44/tmp/mysql.sock -u root -p shutdown
3、在做11步骤的时候可能会无法启动,这里可能是你操作的时候使用root用户,创建的日志是root用户,但是执行是mysql用户,没有权限,所以可以重复执行给mysql配置一下权限命令:
chown -R mysql:mysql /data/mysql/mysql-5.7.44
