Centos 7.6 下Mysql8.0.16编译安装
Centos 7.6 下Mysql8.0.16编译安装
1.最小化安装系统
2.安装基础包
yum -y install ntpdate gcc gcc-c++ ncurses ncurses-devel cmake readline-devel zlib.x86_64 zlib-devel.x86_64 bison libcurl-* net-tool* tree nmap sysstat lrzsz dos2unix telnet.x86_64 nethogs iftop iotop unzip ftp.x86_ 64 xfs* expect vim wget psmisc openssh-client* libaio libaio1 libnuma openssl-devel bzip2
3.基础环境配置
systemctl stop firewalld
systemctl disabled firewalld
systemctl stop postfix
systemctl disable postfix
sed -i 's/^SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config && cat /etc/selinux/config >> ${tmplog_dir}/base.log 2>&1
setenforce 0
getenforce
useradd -M -s /sbin/nologin mysql
mkdir -pv /data/{conf,dumpdir,backupsets,scripts,mysql3306/{data,tmp,logs}}
4.内核参数修改
echo "vm.swappiness=10">>/etc/sysctl.conf echo "net.ipv4.tcp_tw_recycle=1">>/etc/sysctl.conf echo "net.ipv4.tcp_tw_reuse=1">>/etc/sysctl.conf echo "vm.dirty_background_ratio=8">>/etc/sysctl.conf echo "* soft nofile 1024000" >>/etc/security/limits.conf echo "* hard nofile 1024000" >>/etc/security/limits.conf
数据盘挂挂载参数
rw,noatime,nodiratime,nobarrier
5.升级gcc
mkdir /usr/local/tools && cd /usr/local/tools wget http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-5.5.0/gcc-5.5.0.tar.xz tar xf gcc-5.5.0.tar.xz cd gcc-5.5.0 ./contrib/download_prerequisites mkdir build && cd build ../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib make && make install
6.升级cmake
建议另外开一个session防止环境变量未生效
cd /usr/local/tools wget https://github.com/Kitware/CMake/releases/download/v3.14.5/cmake-3.14.5.tar.Z ./bootstrap make && make install
如果出现以下错误
ibstdc++.so.6: version `CXXABI_1.3.9' not found (required by ./destructor)
处理如下：
find / -name "libstdc++.so*" mv /usr/lib64/libstdc++.so.6.0.21 /tmp/ cp /usr/local/tools/gcc-5.5.0/build/x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6.0.21 /usr/lib64/ mv /usr/lib64/libstdc++.so.6 /tmp/ ln -s libstdc++.so.6.0.21 libstdc++.so.6
7.编译安装Mysql
cd /usr/local/tools tar xf mysql-boost-8.0.16.tar.gz cd mysql-8.0.16 cmake . \ -DWITH_BOOST=/usr/local/tools/mysql-8.0.16/boost/boost_1_69_0 \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/data/mysql3306/data \ -DWITHOUT_CSV_STORAGE_ENGINE=1 \ -DWITHOUT_FEDERATED_STORAGE_ENGINE=1 \ -DWITHOUT_ARCHIVE_STORAGE_ENGINE=1 \ -DFORCE_INSOURCE_BUILD=1 \ -DWITH_SSL=system \ -DCMAKE_CXX_COMPILER=/usr/local/bin/g++ \ -DCMAKE_C_COMPILER=/usr/local/bin/gcc make -j 8 make install
8.生成配置文件
注：采用叶总的模板生成的(http://imysql.cn/my_cnf_generator)
cat /data/conf/my3306.cnf [client] port = 3306 socket = /data/mysql3306/data/mysql.sock [mysql] prompt="\u@netdatdb01-137-32 \R:\m:\s [\d]> " no-auto-rehash [mysqld] user = mysql port = 3306 basedir = /usr/local/mysql datadir = /data/mysql3306/data tmpdir = /data/mysql3306/tmp socket = /data/mysql3306/data/mysql.sock pid-file = netdatdb01-137-32.pid character-set-server = utf8mb4 skip_name_resolve = 1 #若你的MySQL数据库主要运行在境外，请务必根据实际情况调整本参数 default_time_zone = "+8:00" open_files_limit = 65535 back_log = 1024 max_connections = 512 max_connect_errors = 1000000 table_open_cache = 1024 table_definition_cache = 1024 table_open_cache_instances = 64 thread_stack = 512K external-locking = FALSE max_allowed_packet = 32M sort_buffer_size = 4M join_buffer_size = 4M thread_cache_size = 768 interactive_timeout = 600 wait_timeout = 600 tmp_table_size = 32M max_heap_table_size = 32M slow_query_log = 1 log_timestamps = SYSTEM slow_query_log_file = /data/mysql3306/slow.log log-error = /data/mysql3306/error.log long_query_time = 0.1 log_queries_not_using_indexes =1 log_throttle_queries_not_using_indexes = 60 min_examined_row_limit = 100 log_slow_admin_statements = 1 log_slow_slave_statements = 1 server-id = 3306 log-bin = /data/mysql3306/logs/mybinlog sync_binlog = 1 binlog_cache_size = 4M max_binlog_cache_size = 2G max_binlog_size = 1G #注意：MySQL 8.0开始，binlog_expire_logs_seconds选项也存在的话，会忽略expire_logs_days选项 expire_logs_days = 7 master_info_repository = TABLE relay_log_info_repository = TABLE gtid_mode = on enforce_gtid_consistency = 1 log_slave_updates slave-rows-search-algorithms = 'INDEX_SCAN,HASH_SCAN' binlog_format = row binlog_checksum = 1 relay_log_recovery = 1 relay-log-purge = 1 key_buffer_size = 32M read_buffer_size = 8M read_rnd_buffer_size = 4M bulk_insert_buffer_size = 64M myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 lock_wait_timeout = 3600 explicit_defaults_for_timestamp = 1 innodb_thread_concurrency = 0 innodb_sync_spin_loops = 100 innodb_spin_wait_delay = 30 transaction_isolation = REPEATABLE-READ #innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 2867M innodb_buffer_pool_instances = 4 innodb_buffer_pool_load_at_startup = 1 innodb_buffer_pool_dump_at_shutdown = 1 innodb_data_file_path = ibdata1:1G:autoextend innodb_flush_log_at_trx_commit = 1 innodb_log_buffer_size = 32M innodb_log_file_size = 2G innodb_log_files_in_group = 2 innodb_max_undo_log_size = 4G innodb_undo_directory = /data/mysql3306/data/undolog innodb_undo_tablespaces = 95 # 根据您的服务器IOPS能力适当调整 # 一般配普通SSD盘的话，可以调整到 10000 - 20000 # 配置高端PCIe SSD卡的话，则可以调整的更高，比如 50000 - 80000 innodb_io_capacity = 4000 innodb_io_capacity_max = 8000 innodb_flush_sync = 0 innodb_flush_neighbors = 0 innodb_write_io_threads = 8 innodb_read_io_threads = 8 innodb_purge_threads = 4 innodb_page_cleaners = 4 innodb_open_files = 65535 innodb_max_dirty_pages_pct = 50 innodb_flush_method = O_DIRECT innodb_lru_scan_depth = 4000 innodb_checksum_algorithm = crc32 innodb_lock_wait_timeout = 10 innodb_rollback_on_timeout = 1 innodb_print_all_deadlocks = 1 innodb_file_per_table = 1 innodb_online_alter_log_max_size = 4G innodb_stats_on_metadata = 0 #注意：MySQL 8.0.16开始删除该选项 #internal_tmp_disk_storage_engine = InnoDB # some var for MySQL 8 log_error_verbosity = 3 innodb_print_ddl_logs = 1 binlog_expire_logs_seconds = 604800 #innodb_dedicated_server = 0 innodb_status_file = 1 #注意: 开启 innodb_status_output & innodb_status_output_locks 后, 可能会导致log-error文件增长较快 innodb_status_output = 0 innodb_status_output_locks = 0 #performance_schema performance_schema = 1 performance_schema_instrument = '%memory%=on' performance_schema_instrument = '%lock%=on' #innodb monitor innodb_monitor_enable="module_innodb" innodb_monitor_enable="module_server" innodb_monitor_enable="module_dml" innodb_monitor_enable="module_ddl" innodb_monitor_enable="module_trx" innodb_monitor_enable="module_os" innodb_monitor_enable="module_purge" innodb_monitor_enable="module_log" innodb_monitor_enable="module_lock" innodb_monitor_enable="module_buffer" innodb_monitor_enable="module_index" innodb_monitor_enable="module_ibuf_system" innodb_monitor_enable="module_buffer_page" innodb_monitor_enable="module_adaptive_hash" [mysqldump] quick max_allowed_packet = 32M
9.初始化数据库
mkdir -pv /data/{mysql3306/{data,logs,tmp},conf,scripts,dumpdir}
/usr/local/mysql/bin/mysqld --defaults-file=/data/conf/my3306.cnf --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql3306/data
10.配置启动脚本
#!/bin/sh
port="3306"
my_lp="3306_system"
mysql_bin="/usr/local/mysql/bin/"
mysql_sock="/data/mysql${port}/data/mysql.sock"
config_file="/data/conf/my3306.cnf"
#start Mysql Services
function_start_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "Starting MySQL_3306 ...\n"
${mysql_bin}/mysqld --defaults-file=${config_file} 2>&1 > /dev/null &
else
printf "MySQL_3306 is running...\n"
exit
fi
}
#stop Mysql Services
function_stop_mysql()
{
if [ ! -e "$mysql_sock" ];then
printf "MySQL_3306 is stopped...\n"
exit
else
printf "Stoping MySQL_3306...\n"
${mysql_bin}/mysqladmin --login-path=${my_lp} -S ${mysql_sock} shutdown
fi
}
#restart Mysql Services
function_restart_mysql()
{
printf "Restarting MySQL_3306...\n"
function_stop_mysql
sleep 2
function_start_mysql
}
case $1 in
start)
function_start_mysql
;;
stop)
function_stop_mysql
;;
restart)
function_restart_mysql
;;
*)
printf "Usage: /data/scripts/mysql3306 {start|stop|restart}\n"
esac
chmod a+x /data/scripts/mysql3306
11.启动服务
/data/scripts/mysql3306 start
12.修改密码
mysql -uroot -p -S /data/mysql3306/data/mysql.sock alter user user() identified by "netdata";
13.设置login-path
mysql_config_editor set --login-path=3306_root -uroot -p -S /data/mysql3306/data/mysql.sock
14.设置环境变量
echo "alias mysql3306='mysql --login-path=3306_root --defaults-file=/data/conf/my3306.cnf --default-character-set=utf8mb4' ">>~/.bashrc source ~/.bashrc
