openEuler下安装mysql
环境:
Os:openEuler 2203sp4
1.1 介质准备
mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz
该介质可以从官网上进行下载
1.1 创建mysql用户和用户组
root@ecs-d7c2-0417412 ~]#groupadd mysql
root@ecs-d7c2-0417412 ~]#useradd mysql -s /sbin/nologin -M -g mysql
1.1 下载解压二进制文件,解压,进入解压出来的文件
[root@localhost soft]# tar -xvf mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz
[root@localhost soft]# mv mysql-5.7.29-linux-glibc2.12-x86_64 /opt/mysql57
[root@localhost soft]# cd /opt/mysql57
[root@localhost mysql5733]# ls
bin docs include lib LICENSE man README share support-files
1.1 在mysql主目录下建立相应的目录
data目录存放数据文件,conf目录存放配置文件
[root@localhost mysql5733]#cd /opt/mysql57
[root@localhost mysql5733]#mkdir data ##数据文件目录
[root@localhost mysql5733]#mkdir conf ## 配置文件目录
[root@localhost mysql5733]#mkdir -p mysqllog/relaylog ##主从环境relaylog
[root@localhost mysql5733]#mkdir -p mysqllog/logfile ##错误日志文件
[root@localhost mysql5733]#mkdir -p mysqllog/binlog ##binlog文件
[root@localhost mysql5733]#mkdir -p secure_file ##secure_file_priv参数指定路
1.1 在conf目录下创建配置文件my.cnf,配置文件内容如下

1.1 修改mysql目录权限
[root@localhost opt]#cd /opt/
[root@localhost opt]# chown -R mysql:mysql ./mysql57
1.1 初始化数据库
./mysqld --initialize --user=mysql --basedir=/opt/mysql57 --datadir=/opt/mysql57/data --lc_messages_dir=/opt/mysql57/share --lc_messages=en_US
[root@localhost bin]# ./mysqld --initialize --user=mysql --basedir=/opt/mysql57 --datadir=/opt/mysql57/data --lc_messages_dir=/opt/mysql57/share --lc_messages=en_US

[root@19c opt]# /opt/mysql57/bin/mysql -h localhost -uroot -P13306 -p
/opt/mysql57/bin/mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
[root@19c ios]# find / -name libncurses.so*
/usr/lib64/libncurses.so.6.3
/usr/lib64/libncurses.so.6
建立一个软连接
ln -s /usr/lib64/libncurses.so.6.3 /usr/lib64/libncurses.so.5
[root@19c opt]# /opt/mysql57/bin/mysql -h localhost -uroot -P13306 -p

建立一个软连接
ln -s /usr/lib64/libtinfo.so.6.3 /usr/lib64/libtinfo.so.5
修改密码
mysql> set password=password('mysql');
删除系统自带用户(看实际情况需要)
mysql> delete from mysql.user where user='mysql.session';
Query OK, 1 row affected (0.06 sec)
mysql> delete from mysql.user where user='mysql.sys';
Query OK, 1 row affected (0.06 sec)
1.1 重启
su - root
/opt/mysql57/bin/mysqladmin -h localhost -uroot -P13306 -pmysql shutdown
/opt/mysql57/bin/mysqladmin -h localhost -uroot -P13306 -p shutdown
/opt/mysql57/bin/mysqld_safe --defaults-file=/opt/mysql57/conf/my.cnf --user=mysql &
1.1 正常登录
