本文主要介绍 centos 系统二进制安装 mysql 5.7.23 版本的安装步骤,其他版本安装过程相似。
1.前置准备
-
卸载旧版mysql
-
查看rpm包
rpm -qa|grep mysql
若有可用rpm -e
卸载 -
查找mysql残留包,有则删除,没有则忽略
find / -name mysql
-
-
安装相关依赖
yum -y install make gcc-c++ cmake bison-devel ncurses-devel numactl libaio
-
创建用户和用户组
groupadd mysql
useradd -s /sbin/nologin -g mysql -m mysql
2.下载二进制安装包并解压
cd /usr/local/ # wget下载或者本地下载后上传 wget https://downloads.mysql.com/archives/get/file/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz # 解压安装包 tar -zxvf mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz # 解压后为了方便后面操作可把解压后文件名修改为mysql mv mysql-5.7.23-linux-glibc2.12-x86_64 mysql # 更改文件夹所属 chown -r mysql.mysql /usr/local/mysql/
3.创建mysql相关目录
mkdir -p /data/mysql/{data,logs,tmp} # 更改文件夹所属 chown -r mysql.mysql /data/mysql/
4.创建mysql配置文件my.cnf
vi /etc/my.cnf # 简单模板如下: [client] port = 3306 socket = /data/mysql/tmp/mysql.sock [mysqld] user = mysql basedir = /usr/local/mysql datadir = /data/mysql/data port = 3306 socket = /data/mysql/tmp/mysql.sock pid-file = /data/mysql/tmp/mysqld.pid tmpdir = /data/mysql/tmp skip_name_resolve = 1 symbolic-links=0 max_connections = 2000 group_concat_max_len = 1024000 sql_mode = no_auto_create_user,no_engine_substitution lower_case_table_names = 1 log_timestamps=system character-set-server = utf8 interactive_timeout = 1800 wait_timeout = 1800 max_allowed_packet = 32m binlog_cache_size = 4m sort_buffer_size = 2m read_buffer_size = 4m join_buffer_size = 4m tmp_table_size = 96m max_heap_table_size = 96m max_length_for_sort_data = 8096 #logs server-id = 1003306 log-error = /data/mysql/logs/error.log slow_query_log = 1 slow_query_log_file = /data/mysql/logs/slow.log long_query_time = 3 log-bin = /data/mysql/logs/binlog binlog_format = row expire_logs_days = 15 log_bin_trust_function_creators = 1 relay-log = /data/mysql/logs/relay-bin relay-log-recovery = 1 relay_log_purge = 1 #innodb innodb_file_per_table = 1 innodb_log_buffer_size = 16m innodb_log_file_size = 256m innodb_log_files_in_group = 2 innodb_io_capacity = 2000 innodb_io_capacity_max = 4000 innodb_flush_neighbors = 0 innodb_flush_method = o_direct innodb_autoinc_lock_mode = 2 innodb_read_io_threads = 8 innodb_write_io_threads = 8 innodb_buffer_pool_size = 2g
5.配置mysql.server
cd /usr/local/mysql/support-files cp mysql.server /etc/init.d/mysql vi /etc/init.d/mysql # 修改目录位置 basedir=/usr/local/mysql datadir=/data/mysql/data # 注册开机启动服务 chkconfig --add mysql chkconfig --list
6.添加环境变量
echo "path=$path:/usr/local/mysql/bin " >> /etc/profile source /etc/profile
7.初始化mysql
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data # 临时密码保存在errlog中 # 获取临时密码 more /data/mysql/logs/error.log |grep password
8.启动mysql服务 并修改密码
# 启动mysql服务 service mysql start # 使用初始密码登录mysql服务 并修改密码 mysql -uroot -p alter user 'root'@'localhost' identified by 'root'; flush privileges;
