简介:

1,官网下载

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.12.tar.gz

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.12.tar.gz

2,添加mysql用户

useradd mysql -s /sbin/nologin

3,安装基础软件

yum -y install wget cmake gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel

4, 解压mysql和解压boost到/usr/local

tar xf mysql-8.0.12.tar.gz
tar zxf mysql-boost-8.0.12.tar.gz -C /usr/local/

5,编译mysql

cd /usr/local/src/mysql-8.0.12
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/mysql-8.0.12/ -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_EMBEDDED_SERVER=1 -DENABLE_DTRACE=0 -DENABLED_LOCAL_INFILE=1 -DDEFAULT_CHARSET=utf8mb4

6,安装mysql

make && make install --大约20分钟

7,配置好my.cnf

8,初始化mysql

cd /usr/local/mysql

mkdir data
chown -R mysql.mysql ./*
chown root.mysql /usr/local/mysql
bin/mysqld --initialize-insecure --user=mysql

9,配置MySQL8

echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

. /etc/profile
cp support-files/mysql.server /etc/init.d/mysql8
chmod +x /etc/init.d/mysql8
sed -i "s@^datadir=.*@datadir=/usr/local/mysql/data@" /etc/init.d/mysql8
sed -i "s@^basedir=.*@basedir=/usr/local/mysql@" /etc/init.d/mysql8
[root@iZwz9hzc7pd8k6u859n9rzZ mysql]# /etc/init.d/mysql8 restart
MySQL server PID file could not be found! [FAILED]
Starting MySQL.

                                     [  OK  ]

99999999999999
10,配置MySQL8 的密码

[root@iZwz9hzc7pd8k6u859n9rzZ mysql]# mysql -u root -p
Enter password:

ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory
报这个错,意思是少了这个插件
需要mysql8自己的客户端才能连接,所以用全路径连接mysql8
[root@iZwz9hzc7pd8k6u859n9rzZ data]# /usr/local/mysql/bin/mysql -u root -p
666666666666666
