1、环境centos7 x64
CentOS Linux release 7.4.1708 (Core) 关闭selinux
下载 https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.38.tar.gz
yum install gcc gcc-c++ ncurses-devel cmake libaio bison perl-Module-Install.noarch -y
2、权限
建立用户
#useradd -r -g mysql -s /sbin/nologin -M mysql
数据库存放目录设置成mysql用户mysql组
mkdir -p /data/mysqldata/3306用来存放数据库并赋予权限
chown -R mysql.mysql /data/mysqldata/3306
3、编译mysql5.6.38.tar.gz，解压 tar zxvf mysql5.6.38.tar.gz
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql3306 -DMYSQL_DATADIR=/data/mysqldata/3306 -DSYSCONFDIR=/usr/local/mysql3306/etc -DMYSQL_UNIX_ADDR=/usr/local/mysql3306/mysql.sock -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
然后执行
make && make install
4、编译完成配置mysql服务权限
# cd /usr/local/mysql3306
# chown -R mysql:mysql .
# mkdir -p /data/mysql
# mkdir -p /usr/local/mysql3306/etc
# chown mysql.mysql -R /data
# chmod 775 -R /data
scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql3306 --datadir=/data/mysqldata/3306/
和配置my.cnf 保持一致
#### chown -R root:mysql . (将权限设置给root用户，并设置给mysql组， 取消其他用户的读写执行权限，仅留给mysql "rx"读执行权限，其他用户无任何权限)
## chown -R mysql:mysql ./data (数据库存放目录设置成mysql用户mysql组)
## chmod -R ug+rwx . (赋予读写执行权限，其他用户权限一律删除仅给mysql用户权限)
# cp support-files/my-default.cnf /usr/local/mysql3306/etc/my.cnf （可以放在/etc/my.cnf）
修改my.cnf配置,先使用简单配置，测试数据库正常后，再增加优化配置
# vi /etc/my.cnf
#[mysqld] 下面添加：
vi /etc/my.cnf
[mysqld]
basedir=/usr/local/mysql3306
datadir=/data/mysqldata/3306
port=3306
socket=/data/mysqldata/3306/mysql.sock
server_id=1
[mysqld_safe]
log-error=/data/mysqldata/3306/log/mysqld.log
备注修改 datadir=/data/mysqldata/3306 需要在 scripts/mysql_install_db --user=mysql 添加 --datadir=/data/mysqldata/3306
5、 启动mysql
# bin/mysqld_safe --user=mysql &
看是否成功
# ps –ef|grep mysql**
将mysql的启动服务添加到系统服务中
# cp support-files/mysql.server /etc/init.d/mysql3306
现在可以使用下面的命令启动mysql
# service mysql3306 start
停止mysql服务
# service mysql3306 stop
重启mysql服务
# service mysql3306 restart
6、修改root用户密码
# cd /usr/local/mysql3306
# ./bin/mysqladmin -u rootpassword
New password:
Confirm new password:
回车在接下来的提示中设置新密码即可。。
# service mysql3306 restart; (重启mysql云服务器)
7、登录mysql测试
#cd
#vim .bash_profile
修改.bash_profile
PATH=$PATH:$HOME/bin:/usr/local/mysql3306/bin
然后source .bash_profile
#mysql -uroot -p
mysql> use mysql;
mysql> select host,user from mysql.user;
8、我这生产环境下my.cnf配置
#
##mysql configure file my.cnf
#
