1.詳細描安裝的過程

1.1關閉防火牆

systemctl stop firewalld.service #中止firewall
systemctl disable firewalld.service #禁止firewall開機啓動
firewall-cmd --state #查看默認防火牆狀態（關閉後顯示notrunning，開啓後顯示running）

1.2 檢查是否安裝NySQL,若是安裝卸載之

rpm -qa |grep mysql
yum remove mysql*

1.3 檢查是否安裝MariaDB,若是安裝卸載之(重要)

rpm -qa |grep mariadb
yum remove mariadb*

1.4 新增用戶/組參數文件

groupadd mysql
useradd -d /home/mysql -g mysql -m mysql
passwd mysql
mysql

vi ~/.bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin:/u01/MySQL5.7/bin

export PATH

[mysql@localhost ~]$ source .bash_profile

1.5 規劃目錄賦權限

mkdir -p /u01/MySQL5.7       

mkdir -p /MySQL/my3306/data
mkdir -p /MySQL/my3306/log/iblog
mkdir -p /MySQL/my3306/log/binlog
mkdir -p /MySQL/my3306/run
mkdir -p /MySQL/my3306/tmp

chown -R mysql:mysql /MySQL/my3306
chown -R mysql:mysql /u01/MySQL5.7
##chown -R 755 /MySQL/my3307

1.6 下載mysql安裝介質到目標機器

[root@localhost ~]# cd /u01/MySQL5.7
[root@localhost MySQL5.7]# ll
total 0
[root@localhost MySQL5.7]# ll
total 696028
-rw-r--r--. 1 mysql mysql 712729170 May 14 01:42 mysql-5.7.22-el7-x86_64.tar.gz

1.8 解壓

[mysql@localhost  MySQL5.7]# tar -xzvf mysql-5.7.22-el7-x86_64.tar.gz  

[mysql@localhost MySQL5.7]# mv  /u01/MySQL5.7/mysql-5.7.22-el7-x86_64/* /u01/MySQL5.7/

1.9初始化數據庫

[mysql@localhost ~]$ mysqld --initialize --user=mysql --basedir=/u01/MySQL5.7  --datadir=/MySQL/my3306/data  --explicit_defaults_for_timestamp
2018-05-14T05:52:52.741612Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000)
2018-05-14T05:52:52.742026Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)
2018-05-14T05:52:53.946033Z 0 [Warning] InnoDB: New log files created, LSN=45790
2018-05-14T05:52:54.104581Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.
2018-05-14T05:52:54.201291Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 0b79b507-573b-11e8-89dd-000c29a1762c.
2018-05-14T05:52:54.203218Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.
2018-05-14T05:52:54.210927Z 1 [Note] A temporary password is generated for root@localhost: ;c_tca9sR;s5

由上可知,初始化的root 密碼爲;c_tca9sR;s5mysql

1.10編輯參數文件 my.cnf

vi /MySQL/my3306/my.cnf

[mysqld]

[client]
port=3306
socket=/MySQL/my3306/run/mysql.sock

[mysql]
socket=/MySQL/my3306/run/mysql.sock

1.11拷貝my.cnf 以及 mysql.server

cp /MySQL/my3306/my.cnf /etc/my.cnf
cp /u01/MySQL5.7/support-files/mysql.server /etc/init.d/mysqld

1.12編輯 /etc/init.d/mysqld

#添加一下兩項
basedir=/u01/MySQL5.7
datadir=/MySQL/my3306/data

1.13.啓動數據庫

[mysql@localhost ~]$ service mysqld start
Starting MySQL.. SUCCESS!

1.14.鏈接數據庫更新初始密碼

[mysql@localhost ~]$ mysql -uroot -p
