linux 编译安装 mysql 5.7.30
本文参考：http://chenzehe.iteye.com/blog/1266260 感谢原作者的分享！
首先安装/更新一些编译时会用到的基础包
[root@localhost local]# yum -y install gcc gcc-c++ make cmake ncurses ncurses-devel libxml2 libxml2-devel openssl-devel bison bison-devel [root@localhost local]#
官网下载mysql 5.7.30版本源码包
编译安装mysql 5.7.30的版本需要gcc支持c++11，不懂的朋友可以看我另外一篇文章：源码安装GCC-4.9.2
1、创建mysql用户
[root@localhost local]# groupadd mysql [root@localhost local]# useradd -s /sbin/nologin -g mysql -M mysql #不允许mysql用户登录 [root@localhost local]#
2、创建数据存放目录
[root@localhost local]# mkdir -pv /data/mysql [root@localhost local]# chown -R mysql.mysql /data/mysql/ #修改目录权限为mysql
3、安装mysql
#官网下载boost文件，解压到当前目录 # 在mysql路径下添加bld文件夹，将编译的文件放在这个文件夹里 mysql-5.7.30
[root@localhost mysql-5.7.30]# mkdir bld [root@localhost mysql-5.7.30]# cmake .. -DMYSQL_UNIX_ADDR=/tmp/mysql.sock\ -DSYSCONFDIR=/usr/local/mysql\ -DMYSQL_TCP_PORT=3306\ -DEXTRA_CHARSETS=all\ -DMYSQL_USER=mysql\ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql\ -DMYSQL_DATADIR=/data/mysql\ -DWITH_XTRADB_STORAGE_ENGINE=1\ -DWITH_FEDERATEDX_STORAGE_ENGINE=1\ -DWITH_ARCHIVE_STORAGE_ENGINE=1\ -DWITH_MYISAM_STORAGE_ENGINE=1\ -DWITH_INNOBASE_STORAGE_ENGINE=1\ -DWITH_ARCHIVE_STPRAGE_ENGINE=1\ -DWITH_BLACKHOLE_STORAGE_ENGINE=1\ -DWIYH_READLINE=1\ -DWIYH_SSL=system\ -DVITH_ZLIB=system\ -DWITH_LOBWRAP=0\ -DWITH_BOOST=/usr/local/src/mysql-5.7.30/boost/boost_1_59_0/\ -DDEFAULT_CHARSET=utf8mb4\ -DDEFAULT_COLLATION=utf8mb4_general_ci [root@localhost mysql-5.7.30]# make [root@localhost mysql-5.7.30]# make install
到这里MariaDB已经算是安装上了，进行配置就可以使用了。本人在这里用的是多实例配置方法
1、配置文件
# 修改my.cnf文件
# 修改my.cnf文件 [mysqld] port = 3306 basedir=/usr/local/mysql datadir=/data/mysql socket=/tmp/mysql.sock #datadir=/var/lib/mysql #socket=/var/lib/mysql/mysql.sock # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Settings user and group are ignored when systemd is used. # If you need to run mysqld under a different user or group, # customize your systemd unit file for mariadb according to the # instructions in http://fedoraproject.org/wiki/Systemd character-set-server = utf8mb4 collation_server = utf8mb4_general_ci lower_case_table_names =1 [mysqld_safe] #log-error=/var/log/mariadb/mariadb.log #pid-file=/var/run/mariadb/mariadb.pid log-error=/data/mysql/mysql.log pid-file=/data/mysql/mysql.pid # # include all files from the config directory # !includedir /etc/my.cnf.d
2、初始化数据目录
#把用到的工具添加到/usr/bin目录
[root@localhost mysql]# ln -s /usr/local/mysql/scripts/mysql_install_db /usr/bin/mysql_install_db [root@localhost mysql]# ./bin/mysqld --defaults-file=/etc/my.cnf \ --basedir=/usr/local/mysql/ \ --datadir=/data/mysql/dbdata/ \ --user=mysql \ --initialize-insecure \ --ssl \ --explicit_defaults_for_timestamp \ --verbose # --initialize-insecure 代表不设置密码，空密码进入， --initialize 设置密码，在日志栏里输出
3、启动数据库
#将/usr/local/mysql/bin加到$PATH环境变量里 [root@localhost mysql]# vi /etc/profile export PATH=/usr/local/mysql/bin:$PATH #插入到最后一行 # 启动 mysql [root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld [root@localhost mysql]# service mysqld start 在启动的时候会加载innodb，中途不能重启，否则会出现如下错误 151114 00:59:38 mysqld started 151114 0:59:38 [Warning] option 'thread_stack': unsigned value 126976 adjusted to 131072 InnoDB: No valid checkpoint found. InnoDB: If this error appears when you are creating an InnoDB database, InnoDB: the problem may be that during an earlier attempt you managed InnoDB: to create the InnoDB data files, but log file creation failed. InnoDB: If that is the case, please refer to InnoDB: http://dev.mysql.com/doc/refman/5.0/en/error-creating-innodb.html 151114 0:59:38 [ERROR] Default storage engine (InnoDB) is not available 151114 0:59:38 [ERROR] Aborting 151114 0:59:38 [Note] /usr/local/mysql/bin/mysqld: Shutdown complete 151114 00:59:38 mysqld ended 删除innodb文件夹，重新启动就可以了
# mysql5.7.30 错误集锦 mysql> show databases; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. 上面这个错误是由于 mysql没有初始化密码，执行以下语句即可 mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER; mysql> flush privileges;
