Mysql5.7版本更新後有不少變化，好比json等，連安裝都有變化，他安裝必需要BOOST庫，不過mysql的官網源碼有帶boost庫的源碼和不帶boost庫的源碼兩種，所以有兩種安裝方式，其實都是同樣的，僅僅是不帶boost庫源碼的須要單獨安裝boost，還有後續文章percona-xtrabackup須要用到boost庫html
下載軟件
到usr/local目錄下：mysql
cd /usr/local wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.11.tar.gz wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.11.tar.gz
安裝boost
注:此處若是隻爲安裝mysql其實能夠不用安裝的，解壓就好，到時安裝mysql時引用目錄，不過percona-xtrabackup須要用到，因此我安裝了。c++
tar xzf boost_1_59_0.tar.gz cd boost_1_59_0 ./bootstrap.sh ./b2 install
不帶boost的mysql源碼安裝
一、安裝依賴包git
yum -y install gcc gcc-c++ ncurses ncurses-devel cmake
二、添加禁止登錄的mysql用戶github
groupadd mysql useradd -r -g mysql -s /bin/false mysql
三、編譯安裝sql
從MySQL 5.7.5開始Boost庫是必需的數據庫
mkdir -p /data/mysql tar xzf mysql-5.7.11.tar.gz cd mysql-5.7.11 cmake . \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/data/mysql \ -DDOWNLOAD_BOOST=1 \ -DWITH_BOOST=/usr/local/boost_1_59_0 \ -DSYSCONFDIR=/etc \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DWITH_FEDERATED_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DENABLE_DTRACE=0 \ -DDEFAULT_CHARSET=utf8mb4 \ -DDEFAULT_COLLATION=utf8mb4_general_ci \ -DWITH_EMBEDDED_SERVER=1 make make install
四、配置開機啓動項json
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld chmod +x /etc/init.d/mysqld chkconfig --add mysqld chkconfig mysqld on
五、配置/etc/my.cnf 僅供參考，能夠不配，用默認的。bootstrap
cat > /etc/my.cnf << EOF [client] port = 3306 socket = /tmp/mysql.sock default-character-set = utf8mb4 [mysqld] port = 3306 socket = /tmp/mysql.sock basedir = /usr/local/mysql datadir = /data/mysql pid-file = /data/mysql/mysql.pid user = mysql bind-address = 0.0.0.0 server-id = 1 init-connect = 'SET NAMES utf8mb4' character-set-server = utf8mb4 #skip-name-resolve #skip-networking back_log = 300 max_connections = 1000 max_connect_errors = 6000 open_files_limit = 65535 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 key_buffer_size = 4M thread_cache_size = 8 query_cache_type = 1 query_cache_size = 8M query_cache_limit = 2M ft_min_word_len = 4 log_bin = mysql-bin binlog_format = mixed expire_logs_days = 30 log_error = /data/mysql/mysql-error.log slow_query_log = 1 long_query_time = 1 slow_query_log_file = /data/mysql/mysql-slow.log performance_schema = 0 explicit_defaults_for_timestamp #lower_case_table_names = 1 skip-external-locking default_storage_engine = InnoDB #default-storage-engine = MyISAM innodb_file_per_table = 1 innodb_open_files = 500 innodb_buffer_pool_size = 64M innodb_write_io_threads = 4 innodb_read_io_threads = 4 innodb_thread_concurrency = 0 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 = 8M 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 EOF
六、初始化數據socket
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
注： 以前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目錄下,且已被廢棄
「–initialize」會生成一個隨機密碼(~/.mysql_secret)，而」–initialize-insecure」不會生成密碼
–datadir目標目錄下不能有數據文件
七、啓動數據庫
service mysqld start
帶boost的mysql源碼安裝
一、安裝依賴包
yum -y install make gcc-c++ cmake bison-devel ncurses-devel bison perl perl-devel perl perl-devel
二、解壓到/usr/local目錄下
tar -zxvf mysql-boost-5.7.11.tar.gz -C /usr/local
三、建立mysql組和用戶
groupadd mysql useradd -r -g mysql -s /bin/false mysql
四、編譯mysql
cd /usr/local/mysql-5.7.11/ cmake -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost make make install
五、把原來的/etc/my.cnf備份
cp /etc/my.cnf /etc/my.cnf.bak rm -f /etc/my.cnf
六、把安裝目錄用戶和組更改成mysql
cd /usr/local/mysql chown -R mysql . chgrp -R mysql .
七、建立一個數據目錄
mkdir -p /data/mysql/data/
八、初始化mysql，及開啓ssl新功能
bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data bin/mysql_ssl_rsa_setup --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data
九、 設爲root是爲了防止普通用戶不當心刪除數據庫
chown -R root . chown -R mysql /data
十、拷貝配置文件
cp support-files//my-default.cnf /etc/my.cnf cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
十一、修改環境變量
vi /etc/profile # 在profile文件末尾增長兩行 PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH export PATH # 使PATH搜索路徑當即生效： source /etc/profile
十二、修改配置文件
vi /etc/my.cnf #修改第19行(取消註釋且修改成) datadir = /data/mysql/data/
1三、啓動
service mysql start
