Write the Code. Change the World.

官网: https://dev.mysql.com/

先下载:
当前最新版本 8.0.19

cd /usr/local/src/

mkdir mysql

cd mysql

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.19.tar.gz

tar -xzvf mysql-boost-8.0.19.tar.gz

创建用户组以及相关目录

groupadd mysql  #创建mysql用户组
useradd -s /sbin/nologin -g mysql -M mysql   #创建mysql用户归属mysql组
mkdir /data/server/mariadb/mysql   #创建安装目录
mkdir -p /data/server/mariadb/data   #创建数据库存放目录
chown -R mysql:mysql  /data/server/mariadb/data   #给予权限

开始编译安装

cd mysql-8-0-19

cmake .  \
-DCMAKE_INSTALL_PREFIX=/alidata/service/mysql/mysql \
-DMYSQL_DATADIR=/alidata/service/mysql/data \
-DSYSCONFDIR=/etc \
-DMYSQL_TCP_PORT=3306 \
-DWITH_BOOST=/usr/local/src/mysql/mysql-8.0.19/boost \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNODB_MEMCACHED=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1

发现报错: Please do not build in-source. Out-of source builds are highly

这个时候这样处理

mkdir build

cd build

再 cmake  .. 后边各种参数

继续报错:

报 Could NOT find Curses 这个。缺少 ncurses-devel , 装个就可以了。

yum install ncurses-devel

然后,再重新 camke,再报错,报 Package ‘libtirpc’, required by ‘virtual:world’, not found

继续安装

yum install libtirpc-devel

继续报错 Could not find rpcgen。 在CentOS8下编译安装MySQL8可能会出现Could not find rpcgen错误,而CentOS8默认的yum源下不提供rpcgen的安装包。所以需要到rpcgen的GitHub仓库上找,

继续报错 Could NOT find BISON

yum install bison

继续报错 Could NOT find Doxygen,然后编译安装 doxygen

git clone https://github.com/doxygen/doxygen.git

cd doxygen

cmake .. -G "Unix Makefiles"

make -j2
sudo make install

然后继续报错Could NOT find FLEX

yum install flex
安装好 doxygen 后,继续编译 mysql。

make -j2

make install

初始化数据库

cd /alidata/service/mysql/mysql

./mysqld --initialize-insecure --user=mysql --basedir=/alidata/service/mysql/mysql --datadir=/alidata/service/mysql/data

设置mysqld

cd /usr/local/src/mysql/superfiles

cp mysql.server.sh /etc/init.d/mysqld

vim /etc/init.d/mysqld

# 修改 dir 配置保存
basedir=/alidata/service/mysql/mysql
datadir=/alidata/service/mysql/data

chmod +x /etc/init.d/mysqld

chkconfig --add mysqld   #添加到系统服务
chkconfig mysqld on   #设置开机自启动   

更改环境变量

vim /etc/profile

PATH=$PATH:/alidata/service/mysql/mysql/bin   

export PATH

source /etc/profile

设置 my.conf

vim /etc/my.conf

# 内容如下
[client]
port=3306
default-character-set=utf8
#user=root
#password=123
[mysqld]
server-id=1
#skip-grant-tables
port=3306
user=mysql
max_connections=200
socket=/alidata/service/mysql/mysql.sock
basedir=/alidata/service/mysql/mysql
datadir=/alidata/service/mysql/data
pid-file=/alidata/service/mysql/mysql.pid
init-connect='SET NAMES utf8'
character-set-server=utf8
default-storage-engine=INNODB
log_error=/alidata/service/mysql/log/mysql-error.log
slow_query_log_file=/alidata/service/mysql/log/mysql-slow.log
[mysqldump]
quick
max_allowed_packet=16M
EOF

授权,设置用户组

chown -R mysql.mysql /alidata/service/mysql/mysql
chown -R mysql.mysql /alidata/service/mysql/data

chmod -R 755 /alidata/service/mysql/mysql
chmod -R 755 /alidata/service/mysql/data

启动 mysql

/etc/init.d/mysqld start

执行安全初始化脚本

# 执行,然后回车
mysql_secure_installation 

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.
The 'validate_password' component is installed on the server.
The subsequent steps will run with the existing configuration
of the component.
Please set the password for root here.  # 设置root用户密码

New password:

Re-enter new password:

Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

 #是否删除匿名用户,生产环境建议删除
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.

#是否禁止root远程登录,根据自己的需求选择Y/n并回车,建议禁止
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.

#是否删除test数据库

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

#是否重新加载权限表,直接回车
Reload privilege tables now? (Press y|Y for Yes, any other key for No) :

 ... skipping.
All done!

到此,设置了 root 用户密码,以及禁用远程登录 root 用户,也删除了匿名用户。那么需要创建一个新用户来使用mysql了。

请看这里: https://blog.vini123.com/382

远程连接 mysql

创建新用户,然后远程连接。

create user shenqi@'%' identified by '33441314';  

# 创建 shenqi 用户,并设置密码。但这样远程连接会报错。
caching_sha2_password' cannot be loaded: dlopen(/usr/local/lib/plugin/caching_sha2_password.so, 

# 使用 mysql_native_password 方式设置密码就好了。
ALTER USER 'shenqi'@'%' IDENTIFIED WITH mysql_native_password BY '33441314';
