CentOS 7.7 yum方式安裝最新版本的MySQL 5.7

一、刪除CentOS 7.7內置的MariaDB相關組件：

# rpm -qa | grep -i mariadb --> mariadb-libs-5.5.64-1.el7.x86_64

# rpm -e --nodeps mariadb-libs-5.5.64-1.el7.x86_64

若是以前安裝過MySQL，先卸載：# rpm -qa | grep -i mysql

若是存在/etc/my.cnf配置文件，先刪除：# rm -rf /etc/my.cnf

二、安裝mysql57-community-release-el7.rpm：

# rpm -ivh http://repo.mysql.com/mysql57-community-release-el7.rpm

備註：安裝後會在/etc/yum.repos.d目錄中生成mysql-community-source.repo和mysql-community.repo

三、安裝MySQL：

# yum list all | grep mysql-community

# yum -y install mysql-community-client mysql-community-common mysql-community-devel mysql-community-libs mysql-community-libs-compat mysql-community-server mysql-community-test

四、初始化MySQL：# mysqld --initialize --user=mysql --datadir=/var/lib/mysql

備註：初始化以前確保/var/lib/mysql目錄爲空

五、修改/etc/my.cnf配置文件：

# mv /etc/my.cnf /etc/my.cnf.bak

# vim /etc/my.cnf

[mysqld]

port=3306

socket=/var/lib/mysql/mysql.sock

datadir=/var/lib/mysql

pid-file=/var/run/mysqld/mysqld.pid

log-error=/var/log/mysqld.log

lower_case_table_names=1

character_set_server=utf8mb4

collation_server=utf8mb4_general_ci

innodb_file_per_table=1

skip_name_resolve=1

slow_query_log=1

slow_query_log_file=mysql-slow.log

symbolic-links=0

explicit_defaults_for_timestamp=1

server_id=1

sync_binlog=1

innodb_flush_log_at_trx_commit=1

log_bin=mysql-bin

log_bin_index=mysql-bin.index

binlog_format=row

六、啓動MySQL服務：

# systemctl start mysqld.service

# systemctl status mysqld.service

# ps aux | grep mysqld

# ss -tunlp | grep 3306

# tail -100 /var/log/mysqld.log

七、配置MySQL服務開機自啓：# systemctl enable mysqld.service

八、查看root@localhost用戶的初始密碼：# grep password /var/log/mysqld.log

九、配置MySQL安全向導：# mysql_secure_installation

十、受權root用戶遠程登陸：

# mysql -uroot -p

mysql> create user root@'192.168.0.%' identified by '123456';

mysql> grant all on *.* to root@'192.168.0.%';

mysql> flush privileges;

十一、使用Navicat Premium鏈接MySQL：
