文档课题：rhel 7.3安装mysql 5.7.21——二进制包Percona-Server-5.7.21-20.
系统：rhel 7.3 64位
数据库：mysql 5.7.21
安装包：Percona-Server-5.7.21-20-Linux.x86_64.ssl101.tar.gz
1、安装包处理
--上传安装包
sftp> lcd F:\installmedium\mysql
sftp> cd /usr/local
sftp> put Percona-Server-5.7.21-20-Linux.x86_64.ssl101.tar.gz

--解压安装包
[root@mysql-leo-percona local]# tar -zxf Percona-Server-5.7.21-20-Linux.x86_64.ssl101.tar.gz

2、创建用户与组
[root@mysql-leo-percona local]# groupadd mysql
[root@mysql-leo-percona local]# useradd -g mysql mysql
[root@mysql-leo-percona local]# chown -R mysql:mysql Percona-Server-5.7.21-20-Linux.x86_64.ssl101
[root@mysql-leo-percona local]# ln -s Percona-Server-5.7.21-20-Linux.x86_64.ssl101 mysql
[root@mysql-leo-percona local]# chown -R mysql:mysql mysql

3、创建目录
[root@mysql-leo-percona ~]# mkdir -p /mysql/data
[root@mysql-leo-percona ~]# mkdir -p /mysql/binlog
[root@mysql-leo-percona ~]# mkdir -p /mysql/bak/file
[root@mysql-leo-percona ~]# chown -R mysql:mysql /mysql

4、创建my.cnf文件
[mysql@mysql-leo-percona ~]$ mkdir etc
[mysql@mysql-leo-percona ~]$ cd etc
[mysql@mysql-leo-percona etc]$ vi my.cnf
添加如下：
[mysql]

#CLIENT#
port                                      = 3306
socket                                    = /mysql/data/mysql.sock

[mysqld]
basedir                                   = /usr/local/mysql
datadir                                   = /mysql/data/
server_id                                 = 1
port                                      = 3306
sql_mode                                  = ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
character_set_server                      = utf8mb4
socket                                    = /mysql/data/mysql.sock
secure-file-priv                          = /mysql/bak/file
log-bin                                   = /mysql/binlog/mysql-bin
log-bin-index                             = /mysql/data/mysql-bin.index
relay-log                                 = /mysql/data/relay-bin
relay-log-index                           = /mysql/data/relay-bin.index

[mysqld_safe]
pid_file                                  = /mysql/data/mysql.pid
log_error                                 = /mysql/data/mysql_error.log

注意：生产环境中参数设置需根据实际情况配置.

5、数据库初始化
$ /usr/local/mysql/bin/mysqld --defaults-file=/home/mysql/etc/my.cnf --initialize --basedir=/usr/local/mysql --datadir=/mysql/data/ --user=mysql

注意：指定配置文件时-defaults-file参数需放第一位，否则初始化可能会出现错误.

6、修改path
[mysql@mysql-leo-percona ~]$ vi .bash_profile
添加如下：
export PATH=$PATH:/usr/local/mysql/bin

7、创建mysql.sock软连接
[mysql@mysql-leo-percona ~]$ ln -s /mysql/data/mysql.sock /tmp/mysql.sock

8、启动mysqld进程
[mysql@mysql-leo-percona ~]$ /usr/local/mysql/bin/mysqld_safe --defaults-file=/home/mysql/etc/my.cnf &
[1] 4180
[mysql@mysql-leo-percona ~]$  mysqld_safe Adding '/usr/local/Percona-Server-5.7.21-20-Linux.x86_64.ssl101/lib/mysql/libjemalloc.so.1' to LD_PRELOAD for mysqld
2023-07-25T06:31:40.958553Z mysqld_safe Logging to '/mysql/data/mysql_error.log'.
2023-07-25T06:31:40.990636Z mysqld_safe Starting mysqld daemon with databases from /mysql/data

9、修改密码
[mysql@mysql-leo-percona ~]$ mysql -uroot -p
Enter password:
