这篇文章主要介绍了Mysql 5.7.21如何在linux平台中安装Part 2,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
目录名称 | 参数名称 | 路径地址 |
---|---|---|
安装目录 | basedir | /usr/local/mysql |
数据文件目录 | datadir | /data/mysql/data |
临时文件目录 | tmpdir | /data/mysql/tmp |
Socket文件目录 | socket | /data/mysql/data/mysql.sock |
bin日志文件目录 | log_bin | /datalog/mysql/binlog |
relay日志文件目录 | relay_log | /datalog/mysql/relaylog |
目前MySQL 社区的GA 提供5 和8 的下载
由于目前大多数系统用的还是5的版本
这里统一使用5的版本
注意,下面是按照5.7.21的版本安装,5.25相同
MySQL CommUnity Server 5.7.25
/usr/sbin/groupadd -g 105 mysql
/usr/sbin/useradd -u 105 -g mysql mysql
echo "mysql123" |passwd mysql --stdin
mkdir -p /data/mysql/software
mkdir -p /usr/local/mysql
mkdir -p /data/mysql/data
mkdir -p /datalog/mysql/binlog
mkdir -p /datalog/mysql/relaylog
chown -R mysql:mysql /usr/local/mysql
mkdir -p /data/mysql/tmp
chown -R mysql:mysql /data/mysql
chown -R mysql:mysql /datalog/mysql/
su - mysql
vim ~/.bash_profile
export MYSQL_HOME=/usr/local/mysql
export PATH=$HOME/bin:$MYSQL_HOME/bin:$PATH
export LD_LIBRARY_PATH=$MYSQL_HOME/lib:$LD_LIBRARY_PATH
source ~/.bash_profile
我们这里建立 /etc/my.cnf

修改my.cnf权限
chown mysql:mysql /etc/my.cnf
libaio-0.3.107-10.el6.x86_64
libaio-devel-0.3.107-10.el6.x86_64
lvm2-2.02.143-7.el6_8.1.x86_64
如果有以前版本的MySQL ,则需要先下载
如只有lib库则可以不用动
RedHat Enterprise Linux 6适用】
# rpm -qa|grep -i mysql
mysql-libs-5.1.71-1.el6.x86_64
Qt-mysql-4.6.2-26.el6_4.x86_64
mysql-5.1.71-1.el6.x86_64
mysql-server-5.1.71-1.el6.x86_64
#yum remove mysql-5.1.71-1.el6.x86_64 qt-mysql-4.6.2-26.el6_4.x86_64 mysql-libs-5.1.71-1.el6.x86_64 mysql-server-5.1.71-1.el6.x86_64
【RedHat Enterprise Linux 7适用】
# rpm -qa|grep -i mariadb*
mariadb-server-5.5.52-1.el7.x86_64
mariadb-libs-5.5.52-1.el7.x86_64
mariadb-embedded-5.5.52-1.el7.x86_64
mariadb-test-5.5.52-1.el7.x86_64
mariadb-bench-5.5.52-1.el7.x86_64
mariadb-5.5.52-1.el7.x86_64
mariadb-devel-5.5.52-1.el7.x86_64
mariadb-embedded-devel-5.5.52-1.el7.x86_64
# yum remove -y mariadb*
su - mysql
tar xzvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /usr/local/mysql/ --strip-components=1
这里将mysql.server文件拷贝值init.d目录使其可以当作服务启停
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
这里修改下面几处
vim /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql/data
lockdir='/data/mysql/data'
mysqld_pid_file_path=/data/mysql/data/mysql.pid
接下来我们初始化MySQL
# su - mysql
$cd /usr/local/mysql
$/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql
初始化过程中可以通过error文件查看进度
tail -f /data/mysql/data/mysql-error.log
$ /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql &
$ netstat -lntp|grep mysqld
后续可以使用如下命令启停数据库
service mysqld stop
service mysqld start
service mysqld restart
设置MySQL自启动
chkconfig mysqld on
默认密码在error文件中有
cat /data/mysql/data/mysql-error.log |grep password
使用如下命令连接
mysql -S /data/mysql/data/mysql.sock -uroot -ppassword
