我的安装目录是: /opt/mysql-5.7.21
#安装依赖包 #MySQL依赖于libaio 库。如果这个库没有在本地安装,数据目录初始化和后续的服务器启动步骤将会失败。请使用适当的软件包管理器进行安装。例如,在基于Yum的系统上: shell> yum search libaio shell> yum install libaio #注意 SLES 11:从MySQL 5.7.19开始,Linux通用tar包的格式是EL6而不是EL5。以致于MySQL客户端bin / mysql需要libtinfo.so.5。解决方法是创建软链接,例如64位系统上的ln -s libncurses.so.5.6 /lib64/libtinfo.so.5或32 位系统上的ln -s libncurses.so.5.6 /lib/libtinfo.so.5。 #创建一个mysql用户和组(注意 此用户仅用于运行mysql服务,而不是登录,因此使用useradd -r和-s /bin/false命令选项来创建对服务器主机没有登录权限的用户。) shell> groupadd mysql shell> useradd -r -g mysql -s /bin/false mysql #解压到指定目录 shell> tar -zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /opt shell> cd /opt shell> mv mysql-5.7.21-linux-glibc2.12-x86_64 mysql-5.7.21 #配置环境变量 echo "export PATH=$PATH:/opt/mysql-5.7.21/bin" >> /etc/profile source /etc/profile #配置数据库目录 数据目录:/opt/mysql-5.7.21/data 参数文件my.cnf:/opt/mysql-5.7.21/etc/my.cnf 错误日志log-error:/opt/mysql-5.7.21/log/mysql_error.log 二进制日志log-bin:/opt/mysql-5.7.21/log/mysql_bin.log 慢查询日志slow_query_log_file:/opt/mysql-5.7.21/log/mysql_slow_query.log 套接字socket文件:/opt/mysql-5.7.21/run/mysql.sock pid文件:/opt/mysql-5.7.21/run/mysql.pid 创建目录: shell> mkdir -p /opt/mysql-5.7.21/{data,log,etc,run} shell> chown -R mysql:mysql /opt/mysql-5.7.21 shell> chmod 750 /opt/mysql-5.7.21/{data,log,etc,run} #配置my.cnf文件 在/opt/mysql-5.7.21/etc/下创建my.cnf文件,加入如下参数,其他参数根据需要配置 shell> touch /opt/mysql-5.7.21/etc/my.cnf shell> chown mysql:mysql /opt/mysql-5.7.21/etc/my.cnf #拷贝my.cnf到/etc/下(拷贝后这个文件为root:root) shell> cp /opt/mysql-5.7.21/etc/my.cnf /etc/ [client] port = 3306 socket = /opt/mysql-5.7.21/run/mysql.sock [mysqld] port = 3306 socket = /opt/mysql-5.7.21/run/mysql.sock pid_file = /opt/mysql-5.7.21/run/mysql.pid basedir = /opt/mysql-5.7.21/ datadir = /opt/mysql-5.7.21/data default_storage_engine = InnoDB max_allowed_packet = 128M max_connections = 2048 open_files_limit = 65535 #skip-name-resolve lower_case_table_names=1 character-set-server = utf8mb4 collation-server = utf8mb4_unicode_ci init_connect='SET NAMES utf8mb4' innodb_buffer_pool_size = 128M innodb_log_file_size = 128M innodb_file_per_table = 1 innodb_flush_log_at_trx_commit = 0 key_buffer_size = 16M log-error = /opt/mysql-5.7.21/log/mysql_error.log log-bin = /opt/mysql-5.7.21/log/mysql_bin.log slow_query_log = 1 slow_query_log_file = /opt/mysql-5.7.21/log/mysql_slow_query.log long_query_time = 5 tmp_table_size = 16M max_heap_table_size = 16M query_cache_type = 0 query_cache_size = 0 server-id=1 #注意 my.cnf 如果加了 skip-name-resolve 后, navicat不能通过 localhost远程连接 #初始化数据库(输出日志到opt/mysql-5.7.21/log/mysql_error.log) shell> 4000 mysqld --initialize --user=mysql --basedir=/opt/mysql-5.7.21 --datadir=/opt/mysql-5.7.21/data #腾讯云服务器遇到(初始化错误信息) mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory 原因:没有安装libnuma.so.1 或者安装时默认安装的是32的,但db2需要的是64位的。 解决办法:1.如果已经安装了libnuma.so.1,先yum remove libnuma.so.1 2.yum -y install numactl.x86_64 #生成一个临时密码,可以在mysql_error.log文件找到 shell> grep 'temporary password' /opt/mysql-5.7.21/log/mysql_error.log #需要注意关于timestamp的设置--explicit_defaults_for_timestamp #生成ssl shell> mysql_ssl_rsa_setup --basedir=/opt/mysql-5.7.21 --datadir=/opt/mysql-5.7.21/data/ shell> chown mysql:mysql /opt/mysql-5.7.21/data/*.pem #配置服务,使用systemctl管理 shell> cd /usr/lib/systemd/system shell> touch mysqld.service

Enter password for user root: The existing password for the user account root has expired. Please set a new password. New password: Re-enter new password: VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin? Press y|Y for Yes, any other key for No: Y There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2 Using existing password for root. Estimated strength of the password: 100 Change the password for root ? ((Press y|Y for Yes, any other key for No) : N ... skipping. By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y Success. All done!

解决MySQL 5.7版本sql_mode=only_full_group_by问题
修改my.cnf 增加如下配置(去掉了 ONLY_FULL_GROUP_BY): sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'
更新YUM源到阿里云源
#没有wget则安装 yum -y install wget cd /etc/yum.repos.d/ mv CentOS-Base.repo CentOS-Base.repo.back #CentOS 5 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo #CentOS 6 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo #CentOS 7 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun a895 .com/repo/Centos-7.repo yum makecache
YUM安装(下载速度慢)
# 检查是否已经安装mysql rpm -qa| grep mysql [root@AY130623132919765ce8Z /]# rpm -qa| grep mysql mysql-devel-5.1.73-8.el6_8.x86_64 mysql-libs-5.1.73-8.el6_8.x86_64 mysql-5.1.73-8.el6_8.x86_64 # 卸载mysql rpm -e mysql --nodeps rpm -e mysql-devel --nodeps rpm -e mysql-libs --nodeps # 查看YUM源 mysql的 yum --enablerepo=remi,remi-test list mysql mysql-server # 配置YUM源 mysql5.7 # MySQL官网中下载YUM源rpm安装包:http://dev.mysql.com/downloads/repo/yum/ Red Hat Enterprise Linux 6 / Oracle Linux 6 (Architecture Independent), RPM Package (mysql57-community-release-el6-9.noarch.rpm) # 下载mysql源安装包 wget --no-check-certificate https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm # 安装mysql源 yum localinstall mysql57-community-release-el6-9.noarch.rpm # 检查mysql源是否安装成功 yum repolist enabled | grep mysql # 可以修改vim /etc/yum.repos.d/mysql-community.repo源,改变默认安装的mysql版本。比如要安装5.6版本,将5.7源的enabled=1改成enabled=0。然后再将5.6源的enabled=0改成enabled=1即可。 #安装 sudo yum install mysql-community-server #启动 service mysqld start service mysqld status
官网下载RPM包安装
清理残留检查是否已经安装mysql
rpm -qa| grep mysql[root@test /]# rpm -qa | grep mysql
mysql-libs-5.1.71-1.el6.x86_64
卸载mysql
rpm -e mysql-libs –nodeps在电脑中查找有关mysql的文件尽可能删掉,如果有的话
比如/etc/my.cc或者/etc/mysql
