如果没有,就可以安装mysql,如果有,需要先卸载(remove后为上面命令查询到的内容,全文件名,我这里没有,没法展示)
yum remove mariadb-xxx
3.解压文件,修改目录名方便配置
tar -zxvf mysql-5.5.62-linux-glibc2.12-x86_64.tar.gz -C /opt/soft/
cd /opt/soft
mv mysql-5.5.62-linux-glibc2.12-x86_64 mysql-5.5.62
4.在/usr/local/目录下创建到/opt/soft/mysql-5.5.62的软链接
cd /usr/local
ln -s /opt/soft/mysql-5.5.62 mysql
5.添加mysql用户,修改mysql目录权限,并用此用户执行应用
useradd -s /bin/false -M mysql
cd /opt/soft
chown -R mysql:mysql mysql-5.5.62
6.安装mysql,进入mysql目录执行以下命令
cd /opt/soft/mysql-5.5.62 ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
出现以下信息,代表成功
7.拷贝配置文件,将mysql的配置文件拷贝为/etc/目录下的my.cnf,并修改配置文件
cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
[mysqld]
# binlog 配置
log-bin=/usr/local/mysql/logs/mysql-bin.log
expire-logs-days=14
max-binlog-size=500M
server-id=1
# GENERAL
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/urs/local/mysql/mysql.sock
user=mysql
default-storage-engine=InnoDB
character-set-server=utf8
lower_case_table_names = 1
[mysqld_safe]
log-error=/usr/local/mysql/mysql-error.log
pid-file=/usr/local/mysql/mysqld.pid
[client]
socket=/usr/local/mysql/mysql.sock
[mysql]
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock
8.拷贝启动程序,将mysql的启动程序拷贝到/etc/init.d/目录下
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
9.安装完,启动mysql服务
service mysqld start
启动成功
10.配置环境变量,编辑/etc/profile,方便在任何地方用mysql命令
vim /etc/profile
#mysql
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin
别忘记重新编译 /etc/profile
source /etc/profile
11.登录mysql,修改密码
首次登录没有密码,提示输入密码时,直接回车就行
mysql -uroot -p
修改mysql root用户密码 为 111111 :
mysql> use mysql; mysql> update user set password=password(‘111111‘) where user=‘root‘ and host=‘localhost‘; mysql> flush privileges;
至此本机登录密码修改完成,若是想让其他机器访问,需要配置远程访问:
GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘111111‘ WITH GRANT OPTION;
使用远程工具测试一下:
至此搭建mysql 5.5.62版本就完成了
12.一些常用命令
service mysqld start #启动
service mysqld stop #关闭
service mysqld restart #重启
service mysqld status #查看运行状态
centos7安装mysql5.5.62
