CentOS 7.1 上编译安装MySQL 5.7.10
1.下载源码
wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.10.tar.gz
2.解压
tar zxvf mysql-5.7.10.tar.gz
3.安装必要的包
sudo yum install cmake gcc-c++ ncurses-devel perl-Data-Dumper libicu-devel libquadmath-devel python-devel bzip2-devel
4.安装Boost
wget http://jaist.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.zip unzip boost_1_59_0.zip cd boost_1_59_0 ./bootstrap.sh ./b2 sudo ./b2 install
5.生成makefile
cmake . -DWITH_SYSTEMD=1加上-DWITH_SYSTEMD=1可以使用systemd控制mysql服务，默认是不开启systemd的。
6.编译
make
7.安装
sudo make install
mysql将会安装到/usr/local/mysql路径。
8.添加mysql用户和组
sudo groupadd mysql sudo useradd -r -g mysql mysql
9.修改目录和文件权限，安装默认数据库
cd /usr/local/mysql sudo chown -R mysql . sudo chgrp -R mysql . sudo bin/mysqld --initialize-insecure --user=mysql
sudo bin/mysql_ssl_rsa_setup sudo chown -R root . sudo chown -R mysql data
至此，mysql就可以启动运行了。
10.启动mysql
CentOS7自带MariaDB的支持，/etc下默认存在my.cnf文件干扰mysql运行，需要先删掉
cd /etc sudo rm -fr my.cnf my.cnf.d
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 = 1 # 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
mysql默认将mysqld.service文件安装到了mysql安装目录下的 usr/lib/systemd/system/，将mysqld.service复制到/usr/lib/systemd/system/目录下
cd /usr/local/mysql/ sudo cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
在mysqld.service，把默认的pid文件指定到了/var/run/mysqld/目录，而并没有事先建立该目录，因此要手动建立该目录并把权限赋给mysql用户。
cd /var/log sudo mkdir mysqld sudo chown -R mysql mysqld sudo chgrp -R mysql mysqld
现在可以使用systemd启动mysql了
sudo systemctl start mysqld
10.修改root密码
/usr/loca/mysql/bin/mysql -uroot
use mysql;
UPDATE user SET authentication_string = PASSWORD('test2015') WHERE user = 'root';
GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'rootpasswd';
FLUSH PRIVILEGES;
至此，安装基本完成了，一个mysql就能用了。
