1.1mysql 5.7(内存至少1G以上，否则编译容易报错)
1.1.1.1下载并配置boost_1_59_0.tar.gz
wget –c http://nchc.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz
mv boost_1_59_0 /usr/local/boost
1.1.1.2下载mysql
wget http://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.25.tar.gz
解压缩
tar –xvf mysql-5.7.25.tar.gz
1.1.1.3源码安装mysql 5.7
安装依赖包
yum install gcc c ncurses-devel libaio bison gcc-c++ git cmake ncurses-devel ncurses -y
开始预编译安装
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql7 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DMYSQL_DATADIR=/data/mysql7 -DSYSCONFDIR=/usr/local/mysql7 -DMYSQL_USER=mysql -DMYSQL_TCP_PORT=3307 -DWITH_XTRADB_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DWITH_EXTRA_CHARSETS=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DWITH_BIG_TABLES=1 -DWITH_DEBUG=0 -DENABLE_DTRACE=0 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost -DWITH_EMBEDDED_SERVER=OFF
collect2: error: ld returned 1 exit status
make[2]: *** [libmysqld/examples/mysql_client_test_embedded] Error 1
make[1]: *** [libmysqld/examples/CMakeFiles/mysql_client_test_embedded.dir/all] Error 2
make: *** [all] Error 2
如果编译如上报错可以添加如该参数试试：-DWITH_EMBEDDED_SERVER=OFF
编译
make –j4 多线程编译速度比较快
安装
make install
1.1.14 添加配置文件创建数据文件目录和启动文件并初始化
创建数据文件目录 mkdir -p /data/mysql7 创建mysql用户 useradd -s /sbin/nologin mysql chown -R mysql. /data/mysql7 添加启动脚本 cp support-files/mysql.server /etc/init.d/mysqld7 chmod +x /etc/init.d/mysqld 添加mysql配置文件 vim /usr/local/mysql7/my.cnf [mysqld] basedir=/usr/local/mysql7/ datadir=/data/mysql7/ port=3307 pid-file=/data/mysql7/mysql7.pid socket=/tmp/mysql.sock [mysqld_safe] log-error=/data/mysql7/mysql7.log #执行初始化 /usr/local/mysql7/bin/mysqld --initialize --user=mysql --datadir=/data/mysql7 --basedir=/usr/local/mysql7/ [root@localhost mysql-5.7.25]# /usr/local/mysql7/bin/mysqld --initialize --user=mysql --datadir=/data/mysql7 --basedir=/usr/local/mysql7/ 2019-12-24T13:11:27.394286Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

1.1.1.5启动mysql
/etc/init.d/mysqld start
1.1.1.6添加物密码登录配置，登录mysql
跳过权限：
vim /usr/local/mysql7/my.cnf
在[mysqld]字段下添加：
skip-grant-tables
重启mysql
/etc/init.d/mysqld restart
1.1.1.7免密登录mysql设置：并更新mysql密码：
update mysql.user set authentication_string=password(‘123456‘) where user="root";
1.1.1.8输入密码也能够正常登录，去掉免密登录配置，重启后正常登录
去掉skip-grant-tables：
[root@localhost bin]# more ../my.cnf [mysqld] basedir=/usr/local/mysql7/ datadir=/data/mysql7/ port=3306 pid-file=/data/mysql7/mysql7.pid socket=/tmp/mysql.sock [mysqld_safe] log-error=/data/mysql7/mysql7.log [root@localhost bin]#
重启mysql： [root@localhost mysql7]# /etc/init.d/mysqld restart Shutting down MySQL.. SUCCESS! Starting MySQL. SUCCESS! 重启登录输入用户密码：root/123456 [root@localhost bin]# ./mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.
