yum install -y gcc gcc-c++ ncurses-devel perl openssl-devel
最最重要的是,不要忘了安装openssl-devel

2、安装cmake
tar -xzvf cmake-3.8.1.tar.gz cd cmake-3.8.1 ./bootstrapmake && make install
3、安装mysql5.7.18
首先下载安装包,本人的安装版本是:mysql-boost-5.7.18.tar.gz
需要下载boost,本人配套的是boost_1_59_0版本
下载,并在/usr/local目录下解压,并重命名为boost
首先为添加 mysql 对应的系统账户,用于保证其本地文件权限分配:
groupadd mysqluseradd -r -g mysql mysql
创建数据库目录:
mkdir -p /var/mysql/datachown mysql:mysql /var/mysql/data
进入解压后的mysql安装包:
cd mysql-boost-5.7.18cmake . \-dcmake_install_prefix=/usr/local/mysql/ \-dinstall_datadir=/usr/local/mysql/data/master \-dsysconfdir=/usr/local/mysql/etc \-ddefault_charset=utf8 \-ddefault_collation=utf8_general_ci \-dextra_charsets=all \-dwith_ssl=system \-dwith_embedded_server=1 \-denabled_local_infile=1 \-dwith_myisam_storage_engine=1 \-dwith_innobase_storage_engine=1 \-dwith_archive_storage_engine=1 \-dwith_blackhole_storage_engine=1 \-dwith_memory_storage_engine=1 \-dwith_federated_storage_engine=1 \-dwith_partition_storage_engine=1 \-dwith_perfschema_storage_engine=1 \-dmysql_user=mysql \-dmysql_unix_addr=/usr/local/mysql/data/mysql.sock \-ddownload_boost=1 \-dwith_boost=/usr/local/boost
如果发生错误,修改好后,需要删除当前目录下的cmakecache.txt文件,再重新cmake
make && make install
进行完以上步骤,需要改变 mysql 安装目录的所有者,比如我们安装的目录是 /usr/local/mysql,使用命令
chown -r mysql:mysql /usr/local/mysql
修改目录所有者。此时,复制一份默认配置文件
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
博主安装完成没有my-default.cnf 这个文件,需要自己创建,附上文件的内容:
#for advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html# *** do not edit this file. it's a template which will be copied to the# *** default location during install, and will be replaced if you# *** upgrade to a newer version of mysql.[mysqld]#aracter_set_server=utf8#init_connect='set names utf8' sql_mode=no_engine_substitution,strict_trans_tables # 一般配置选项basedir = /usr/local/mysqldatadir = /usr/local/mysql/data/masterport = 3306socket = /usr/local/mysql/data/mysql.sockcharacter-set-server=utf8back_log = 300max_connections = 3000max_connect_errors = 50table_open_cache = 4096max_allowed_packet = 32m#binlog_cache_size = 4mmax_heap_table_size = 128mread_rnd_buffer_size = 16msort_buffer_size = 16mjoin_buffer_size = 16mthread_cache_size = 16query_cache_size = 128mquery_cache_limit = 4mft_min_word_len = 8thread_stack = 512ktransaction_isolation = repeatable-readtmp_table_size = 128m#log-bin=mysql-binlong_query_time = 6server_id=1innodb_buffer_pool_size = 1ginnodb_thread_concurrency = 16innodb_log_buffer_size = 16minnodb_log_file_size = 512minnodb_log_files_in_group = 3innodb_max_dirty_pages_pct = 90innodb_lock_wait_timeout = 120innodb_file_per_table = on[mysqldump]quickmax_allowed_packet = 32m[mysql]no-auto-rehashdefault-character-set=utf8safe-updates[myisamchk]key_buffer = 16msort_buffer_size = 16mread_buffer = 8mwrite_buffer = 8m[mysqlhotcopy]interactive-timeout[mysqld_safe]open-files-limit = 8192[client]port=3306socket=/usr/local/mysql/data/mysql.sock#default-character-set=utf8
如果提示已存在文件是否覆盖时,覆盖即可。
然后执行数据库的初始化操作,
/usr/local/mysql/bin/mysqld --initialize --user=mysql,
这时候会初始化数据库并创建一个数据库 root 账号,但是要注意,这个账号是有默认密码的,初始化的时候屏幕上会输出初始化的密码,如果错过了,可以通过查看 /root/.mysql_secret 即可看到默认的密码。
执行 cp /usr/local/mysql/support-files/mysql.server /etc/init.d,将 mysql 的服务启动脚本复制过去,然后执行 service mysql.server start 启动 mysql。
最后 /usr/local/mysql/bin/mysql -rroot -p,输入密码回车,如果出现access denied for user 'root'@'localhost' (using password: yes),一般情况下
service mysql.server restart 重新启动即可
通过之后,可以用以下命令重新设置root密码
set password=password('你的密码');
至此,基本的安装流程完毕
以下方法可以设置开机启动
命令echo service mysqld start >> /etc/rc.local
或者进入/etc/目录,直接vim rc.local编辑rc.local文件,在最后一行添加“service mysqld start”,保存退出。
以上就是centos系统下安装mysql5.7.18方法详解的详细内容。
