银河麒麟V10环境安装MySQL

最近在信创操作系统：银河麒麟V10下部署了一遍MySQL，走了点弯路，后来在大佬的指点下成功部署，在此予以记录~

准备工作

安装MySQL之前要先检测系统是否带有MySQL和mariadb，如果有建议全部删掉，否则和本包安装的时候有冲突。

  1. 查看系统是否自带MySQL和mariadb
rpm -qa | grep mysql
rpm -qa | grep mariadb
  1. 删除MySQL和mariadb相关包
rpm -e filename
  1. 查询所有的MySQL相关的文件，然后统统删掉
find / -name mysql

正式部署

  1. 将MySQL的tar包放在/root路径下，并解压
mv mysql-XXXX.tar /root
tar -xf mysql-XXXX.tar

  1. 进入MySQL目录编译安装
cd mysql-XXXX

cmake -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost

make && make install

  1. 查看是否有MySQL用户及用户组，若没有则添加
cat /etc/group | grep mysql
groupadd mysql
useradd -r -g mysql mysql
  1. 对创建的用户进行MySQL文件的授权，注意此处的MySQL是安装后的路径，而不是一开始解压缩的路径
chown -R mysql:mysql /usr/local/mysql
  1. 需要编辑/etc/myf(如果没有则创建)，格式不唯一，仅供参考

socket = /tmp/mysql.sock

[mysqld]

[mysql]
no-auto-rehash

[myisamchk]
key_buffer_size = 32M
sort_buffer_size = 768K
read_buffer = 2M
write_buffer = 2M

  1. 给配置文件权限，权限不对，后面会一直报error
chmod 644 /etc/myf
  1. 初始化MySQL在/usr/local/mysql/bin/下执行
./mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
  1. 拷贝可执行文件
cp mysql.server /etc/init.d/mysqld

到这里就安装部署完成了，下面来做一个小小的启动连接测试~

测试

  1. 启动MySQL服务，若成功则如图所示会显示有succeed
service mysqld start

  1. 查看MySQL服务状态
service mysqld status

  1. 连接测试（在MySQL的bin目录下执行），第一次登陆无密码
./mysql -hlocalhost -uroot -p


4.停止MySQL服务

service mysqld stop
