1、編譯安裝MySQL8.0
#版本信息
#cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)
#安裝依賴包
yum -y install wget cmake gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel rpm -qa |grep libaio yum install libaio libaio-devel
#下載源碼包
wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-boost-8.0.12.tar.gz
#創建用戶和建立數據目錄並賦予用戶目錄權限
groupadd mysql useradd -r -g mysql -s /sbin/nologin mysql mkdir -p /usr/local/mysql mkdir -p /data/mysql chown -R mysql.mysql /usr/local/mysql chown -R mysql.mysql /data/mysql chmod -R 755 /usr/local/mysql/ chmod -R 755 /data/mysql/
#解壓並開始安裝
tar -zxf mysql-boost-8.0.12.tar.gz
#配置
cd mysql-8.0.12 cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/data/mysql \ -DSYSCONFDIR=/etc \ -DMYSQL_TCP_PORT=3306 \ -DWITH_BOOST=~/mysql-8.0.12/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
#配置參數說明：
CMAKE_INSTALL_PREFIX ：指定基礎安裝目錄 MYSQL_DATADIR ：指定數據目錄 SYSCONFDIR=/etc ：指定配置文件掃描目錄 MYSQL_TCP_PORT ：指定端口號 WITH_BOOST ：指定boost所在目錄 DEFAULT_CHARSET ：指定默認字符集 DEFAULT_COLLATION ：指定默認排序規則 ENABLED_LOCAL_INFILE=ON ：是否爲load data infile啓用local WITH_INNODB_MEMCACHED=ON :是否生成memcached共享庫
#編譯&安裝
make && make install
#初始化數據庫
mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
#建立配置文件
cat > /etc/my.cnf <<EOF [client] port=3306 socket=/tmp/mysql.sock default-character-set=utf8 #user=root #password=123 [mysqld] server-id=1 #skip-grant-tables port=3306 user=mysql max_connections=200 socket=/tmp/mysql.sock basedir=/usr/local/mysql datadir=/data/mysql pid-file=/data/mysql/mysql.pid init-connect='SET NAMES utf8' character-set-server=utf8 default-storage-engine=INNODB log_error=/data/mysql/mysql-error.log slow_query_log_file=/data/mysql/mysql-slow.log [mysqldump] quick max_allowed_packet=16M EOF
#配置環境變量
echo "PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile source /etc/profile
#配置啓動腳本
cp ../mysql-8.0.12/support-files/mysql.server /etc/init.d/mysqld vim /etc/init.d/mysqld chmod +x /etc/init.d/mysqld /etc/init.d/mysqld start
#centos7系統自啓動腳本

#啓動MySQL
systemctl start mysqld.service
#修改root密碼：使用WITH指定認證方式
mysql -uroot ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密碼'; ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY '你的密碼';
#查看密碼字段和加密方式
select host, user, authentication_string, plugin from user;
2、yum存儲庫安裝MySQL
wget https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm yum localinstall mysql80-community-release-el7-1.noarch.rpm yum repolist enabled|grep "mysql.*-community.*" yum repolist all|grep mysql yum install mysql-community-server systemctl enable mysqld systemctl start mysqld netstat -lntup|grep 3306
#查看隨機生成的密碼
grep 'temporary password' /var/log/mysqld.log mysql -uroot -p
#修改密碼,密碼必須要由大小寫字母、數字和特性字符組成
alter user 'root'@'localhost' identified by '[email protected]'; select version();
