CentOS7.1 上编译安装mysql

tiyan

1.官网下载源码 　　https://www.mysql.com/ 　　 　　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 　　 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 . 　　 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/ sudo chown -R mysql：mysql mysql/ bin/mysqld --initialize-insecure --user=mysql [python] view plaincopy 　　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 　　现在可以启动mysql了 　　sudo /usr/local/mysql/bin/mysqld_safe --user=mysql & 　　CentOS7 不能使用service控制mysql服务，而源码安装的mysql也没有提供Systemd的控制脚本。 　　于是编辑/etc/rc.d/rc.local文件，添加mysql的开机启动命令。 　　/usr/local/mysql/bin/mysqld_safe --user=mysql & 　　然后给/etc/rc.d/rc.local添加可执行权限 　　sudo chmod a+x /etc/rc.d/rc.local 　　 11.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。
