一、下载源码包
mkdir /usr/local/src/mysql-5.7.26-src cd /usr/local/src/mysql-5.7.26-src wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26.tar.gz
二、添加mysql用户和组
[root@node2 ~]# groupadd mysql [root@node2 ~]# id myql id: myql: no such user [root@node2 ~]# useradd -d /home/myql -g mysql -m mysql [root@node2 ~]# id mysql uid=1000(mysql) gid=1000(mysql) 组=1000(mysql)
[root@node2 ~]# passwd mysql 更改用户 mysql 的密码 。 新的 密码： 重新输入新的 密码： passwd：所有的身份验证令牌已经成功更新。
三、新建相关目录，并赋权限给mysql用户
[root@node2 home]# mkdir /home/mysql-5.7.26 [root@node2 home]# mkdir /home/mysql-5.7.26/data [root@node2 home]# mkdir -p /home/mysql-5.7.26/log[root@node2 home]# mkdir -p /home/mysql-5.7.26/run [root@node2 home]# mkdir -p /home/mysql-5.7.26/tmp
[root@node2 home]# chown -R mysql:mysql /home/mysql-5.7.26/ [root@node2 home]# ll 总用量 0 drwxr-xr-x 6 mysql mysql 51 5月 3 16:25 mysql-5.7.26 [root@node2 home]# cd mysql-5.7.26/ [root@node2 mysql-5.7.26]# ll 总用量 0 drwxr-xr-x 2 mysql mysql 6 5月 3 16:24 data drwxr-xr-x 4 mysql mysql 33 5月 3 16:25 log drwxr-xr-x 2 mysql mysql 6 5月 3 16:25 run [root@node2 mysql-5.7.26]# chmod -R 755 /home/mysql-5.7.26/ [root@node2 mysql-5.7.26]# ll 总用量 0 drwxr-xr-x 2 mysql mysql 6 5月 3 16:24 data drwxr-xr-x 4 mysql mysql 33 5月 3 16:25 log drwxr-xr-x 2 mysql mysql 6 5月 3 16:25 run
四、解压源码包
cd /usr/local/src/mysql-5.7.26-src tar -zxvf mysql-5.7.26.tar.gz
五、安装相关依赖包
yum install cmake gcc gcc-c++ ncurses-devel bison zlib libxml openssl automake autoconf make libtool bison-devel libaio-devel
六、安装boost
cd /usr/local wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz tar -zxvf boost_1_59_0.tar.gz
七、编译安装
cmake \ -DCMAKE_INSTALL_PREFIX=/home/mysql-5.7.26 \ #安装目录
-DINSTALL_DATADIR=/home/mysql-5.7.26/data \ #数据目录
-DDEFAULT_CHARSET=utf8 \ #默认编码
-DDEFAULT_COLLATION=utf8_general_ci \ #默认校验规则
-DEXTRA_CHARSETS=all \
-DWITH_SSL=yes \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_MYISAM_STORAGE_ENGINE=1 \ #激活myisam
-DWITH_INNOBASE_STORAGE_ENGINE=1 \ #激活innodb
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \ #
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DMYSQL_UNIX_ADDR=/home/mysql-5.7.26/run/mysql.sock \ #sock目录
-DMYSQL_TCP_PORT=3306 \ #端口
-DENABLED_LOCAL_INFILE=1 \ #允许导入数据
-DSYSCONFDIR=/etc \
-DWITH_READLINE=on \ #快捷键功能
-DWITH_BOOST=/usr/local/boost_1_59_0 \ #增强插件
make
最后出现：
[100%] Building CXX object mysql-test/lib/My/SafeProcess/CMakeFiles/my_safe_process.dir/safe_process.cc.o Linking CXX executable my_safe_process [100%] Built target my_safe_process
编译成功，再执行
make install
最后出现：
-- Installing: /home/mysql-5.7.26/./COPYING-test -- Installing: /home/mysql-5.7.26/./README-test -- Up-to-date: /home/mysql-5.7.26/mysql-test/mtr -- Up-to-date: /home/mysql-5.7.26/mysql-test/mysql-test-run -- Installing: /home/mysql-5.7.26/mysql-test/lib/My/SafeProcess/my_safe_process -- Up-to-date: /home/mysql-5.7.26/mysql-test/lib/My/SafeProcess/my_safe_process -- Installing: /home/mysql-5.7.26/mysql-test/lib/My/SafeProcess/Base.pm -- Installing: /home/mysql-5.7.26/support-files/mysqld_multi.server -- Installing: /home/mysql-5.7.26/support-files/mysql-log-rotate -- Installing: /home/mysql-5.7.26/support-files/magic -- Installing: /home/mysql-5.7.26/share/aclocal/mysql.m4 -- Installing: /home/mysql-5.7.26/support-files/mysql.server
进入/home/mysql-5.7.26/目录
[root@node2 mysql-5.7.26]# ll 总用量 64 drwxr-xr-x 2 root root 4096 5月 15 09:08 bin -rw-r--r-- 1 root root 17987 4月 13 21:32 COPYING -rw-r--r-- 1 root root 17987 4月 13 21:32 COPYING-test drwxr-xr-x 2 mysql mysql 6 5月 3 16:24 data drwxr-xr-x 2 root root 55 5月 15 09:08 docs drwxr-xr-x 3 root root 4096 5月 15 09:08 include drwxr-xr-x 4 root root 192 5月 15 09:08 lib drwxr-xr-x 4 mysql mysql 33 5月 3 16:25 log drwxr-xr-x 4 root root 30 5月 15 09:08 man drwxr-xr-x 10 root root 4096 5月 15 09:08 mysql-test -rw-r--r-- 1 root root 2478 4月 13 21:32 README -rw-r--r-- 1 root root 2478 4月 13 21:32 README-test drwxr-xr-x 2 mysql mysql 6 5月 3 16:25 run drwxr-xr-x 28 root root 4096 5月 15 09:08 share drwxr-xr-x 2 root root 90 5月 15 09:08 support-files drwxr-xr-x 2 mysql mysql 6 5月 3 16:25 tmp
安装成功
八、编写配置文件my.cnf
mkdir /etc/mysql cd /etc/mysql vim my.cnf [mysqld] basedir=/home/mysql-5.7.26 datadir=/home/mysql-5.7.26/data socket=/home/mysql-5.7.26/mysql.sock user=mysql symbolic-links=0 [mysqld_safe] log-error=/home/mysql-5.7.26/log/mysqld.log pid-file=/home/mysql-5.7.26/run/mysqld.pid
九、初始化系统数据库
[root@node2 bin]# ./mysqld –defaults-file=/etc/mysql/my.cnf --initialize --user=mysql --basedir=/home/mysql-5.7.26/ --datadir=/home/mysql-5.7.26/data/
2019-05-15T06:29:58.880090Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2019-05-15T06:30:00.176430Z 0 [Warning] InnoDB: New log files created, LSN=45790 2019-05-15T06:30:00.525258Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2019-05-15T06:30:00.673537Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started.

这里显示了第一次登陆时的临时密码，需要记下来
十、启动
[root@node2 bin]# touch /home/mysql-5.7.26/log/mysqld.log [root@node2 bin]# chown -R mysql:mysql /home/mysql-5.7.26/log/mysqld.log [root@node2 bin]# ./mysqld_safe --defaults-file=/etc/mysql/my.cnf --user=mysql 2019-05-15T06:33:33.794898Z mysqld_safe Logging to '/home/mysql-5.7.26/log/mysqld.log'. 2019-05-15T06:33:33.826283Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7.26/data
十一、添加MySQL服务
cp /home/mysql-5.7.26/support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
十二、启动服务
[root@node2 bin]# service mysqld start
Starting MySQL. SUCCESS!
十三、添加mysql的环境变量
vim /etc/profile 最后一行添加 export PATH=/home/mysql-5.7.26/bin:$PATH
source /etc/profile
十四、连接mysql
先查看mysqld.log日志，查找初始密码，初始密码是在第一次运行初始化数据库时由系统生成的
[root@node2 data]# cat /home/mysql-5.7.26/log/mysqld.log |grep password 2019-05-15T03:34:45.137254Z 1 [Note] A temporary password is generated for root@localhost: 1ws;,dEy?kM#
