卸载mariadb
# rpm -qa mariadb* mariadb-libs-5.5.44-2.el7.centos.x86_64 # rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64
一、对于centos 7 安装mySql依赖项
yum install gcc gcc-c++ make cmake bison bison-devel ncurses ncurses-devel libaio-devel perl autoconf automake zlib* fiex* libxml* libmcrypt* libtool-ltdl-devel*
二、创建用户
设置MySQL用户和组
groupadd mysql
useradd -r -g mysql mysql
三、新建MySQL所需要的目录
- -p /mysql/app
mkdir -p /mysql/app/data
mkdir -p /mysql/app/tmp
mkdir -p /mysql/app/logs
mkdir -p /mysql/app/etc
四、上传源码文件
解压编译
cmake -DCMAKE_INSTALL_PREFIX=/mysql/app -DMYSQL_DATADIR=/mysql/app/data -DSYSCONFDIR=/mysql/app/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/mysql/app/tmp/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost
参数解析:
- CMAKE_INSTALL_PREFIX:指定MySQL程序的安装目录,默认/usr/local/mysql
- DEFAULT_CHARSET:指定服务器默认字符集,默认latin1
- DEFAULT_COLLATION:指定服务器默认的校对规则,默认latin1_general_ci
- ENABLED_LOCAL_INFILE:指定是否允许本地执行LOAD DATA INFILE,默认OFF
- WITH_COMMENT:指定编译备注信息
- WITH_xxx_STORAGE_ENGINE:指定静态编译到mysql的存储引擎,MyISAM,MERGE,MEMBER以及CSV四种引擎默认即被编译至服务器,不需要特别指定。
- WITHOUT_xxx_STORAGE_ENGINE:指定不编译的存储引擎
- SYSCONFDIR:初始化参数文件目录
- MYSQL_DATADIR:数据文件目录
- MYSQL_TCP_PORT:服务端口号,默认3306
- MYSQL_UNIX_ADDR:socket文件路径,默认/tmp/mysql.sock
- DDOWNLOAD_BOOST=1 :下载boost库
- DWITH_BOOST=/usr/local/boost 安装boost库
编译安装
make && make install
## 出错的情况下 需要重新编译才执行 否则不用操作 下面这两条命令 make clean rm -f CMakeCache.txt
五、创建配置文件my.cnf
vi /mysql/app/etc/my.cnf
[client] port = 3306 socket = /mysql/tmp/mysqld.sock [mysqld] port = 3306 pid-file = /mysql/tmp/mysqld.pid socket = /mysql/tmp/mysqld.sock datadir = /mysql/data log_error = /mysql/logs/mysql-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /mysql/logs/mysql-slow.log #symbolic-links=0 #分区 user = mysql bind-address = 0.0.0.0 character_set_server=utf8 init_connect='SET NAMES utf8' server-id = 1 skip-name-resolve back_log = 600 max_connections = 10240 max_connect_errors = 10000 open_files_limit = 10240 table_open_cache = 128 max_allowed_packet = 4M binlog_cache_size = 1M max_heap_table_size = 8M tmp_table_size = 16M read_buffer_size = 2M read_rnd_buffer_size = 8M sort_buffer_size = 8M join_buffer_size = 8M thread_cache_size = 64 ##线程缓存 query_cache_size = 32M ##查询缓存大小 query_cache_limit = 2M key_buffer_size = 4M ft_min_word_len = 4 transaction_isolation = REPEATABLE-READ log_bin = mysql-bin binlog_format = mixed expire_logs_days = 30 performance_schema = 0 explicit_defaults_for_timestamp skip-external-locking default-storage-engine = InnoDB innodb_file_per_table = 1 innodb_open_files = 1024 innodb_buffer_pool_size = 512M innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_purge_threads = 1 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 2M innodb_log_file_size = 32M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 bulk_insert_buffer_size = 8M myisam_sort_buffer_size = 32M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 interactive_timeout = 28800 wait_timeout = 28800 [mysqldump] quick max_allowed_packet = 16M [myisamchk] key_buffer_size = 8M sort_buffer_size = 8M read_buffer = 4M write_buffer = 4M [mysql] #character_set_server=utf8
六、授权用户
chown -R mysql:mysql /mysql/app chown -R mysql:mysql /mysql/app/data chmod 1777 /mysql/app/tmp
七、设置环境变量
echo 'export PATH=/mysql/app/bin:$PATH' >>/etc/profile
source !$
八、创建服务启动脚本,添加开机启动
cp /mysql/app/support-files/mysql.server/etc/init.d/mysqld chmod +x /etc/init.d/mysqld //给脚本添加执行权限 vi /etc/init.d/mysqld //服务启动脚本要修改以下两个参数 basedir=/mysql/app //MySQL安装目录 datadir= /mysql/app/data //数据存放目录 conf=/mysql/etc/my.cnf //配置文件路径 chkconfig mysqld on //添加开机启动
九、初始化数据库
/mysql/app/bin/mysqld --initialize --user=mysql --basedir=/mysql/app --datadir=/mysql/app/data/
- /mysql/app/logs/mysql-error.log
- 记录临时密码
十、重启mysql
service mysqld restart
十一、登陆
- mysql -u root -p
- 输入临时密码
- 修改root密码
- SET PASSWORD = PASSWORD('新密码');
- ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
- flush privileges;
