centos7下编译安装mysql

下载

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.23.tar.gz

解压

tar zxvf mysql-5.6.23.tar.gz

安装编译环境

sudo yum install cmake gcc-c++ ncurses-devel perl-Data-Dumper

编译安装

进入mysql源码目录，生成makefile

cmake .

make

make install

mysql将会安装到/usr/local/mysql路径。

修改目录和文件权限，初始化数据库

cd /usr/local/mysql
sudo chown -R mysql .
sudo chgrp -R mysql .
sudo scripts/mysql_install_db --user=mysql

修改my.cnf文件

/etc下默认存在my.cnf文件干扰mysql运行，需要先删掉，然后再/etc下重建my.cnf文件，内容如下：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html 
[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = /data/mysql/data
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

max_connection = 10000
sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

#binary log
log-bin = mysql-bin
binlog_format = mixed
expire_logs_day = 30

#slow query log
slow_query_log = 1
slow_query_log_file = /var/log/mysql/slow.log
long_query_time = 3
log-queries-not-using-indexes
log-slow-admin-statements

将mysql加入到系统服务中：

cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
service mysql start

附：可能出现下面问题：

Starting MySQL................ ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid).

说明需要给/usr/local/mysql/data目录读写权限这里直接用：

sudo chmod 777 /usr/local/mysql/data

还需要重启机器：

reboot

还有将mysql命令加入环境变量：

export PATH=/usr/local/mysql/bin:$PATH

安装5.6版本的初始化工具

执行命令行(前提是mysql已经启动)：

mysql_secure_installation

按照提示初始化即可

以上
