修改容器映射端口
宿主機/var/lib/docker/containers/容器名稱/hostconfig.json 修改hostport
nginx
nginx/conf.d/default.conf配置
location ~ .phpdocument_root$fastcgi_script_name;
include fastcgi_params;
}
php
設(shè)置php.ini
mv /docker-service/php/php/php/php.ini-production /docker-service/php/php/php
docker-php添加擴展
docker exec -it 999 /bin/bash
docker-php-ext-install pdo_mysql
pecl install igbinary
在php.ini添加 extension=igbinary.so
pecl install redis && docker-php-ext-enable redis
詢問是否開啟擴展支持 輸入no
在php.ini添加 extension=/usr/local/lib/php/extensions/no-debug-non-zts-20180731/igbinary.so
在php.ini添加 extension=/usr/local/lib/php/extensions/no-debug-non-zts-20180731/redis.so
mariadb
配置文件位置
/etc/mysql/my.cnf 數(shù)據(jù)庫配置文件
查看端口命令 show global variables like 'port';
/etc/mysql/conf.d/docker.cnf 可用于忘記密碼
忘記密碼
docker cp mariadb:/etc/mysql/conf.d/docker.cnf ./docker.cnf
在docker.cnf添加skip-grant-tables
docker cp ./docker.cnf mariadb:/etc/mysql/conf.d/docker.cnf
登錄mariadb mysql -uroot -p 無密碼登錄
flush privileges;
alter user 'root'@'localhost' identified by '123456';
flush privileges;
在docker.cnf刪除skip-grant-tables
docker-compose restart mariadb
主主配置（雙主）
主機/從機分別在配置文件my.cnf中添加：
server-id=145 ##或者147不同主機的id唯一標(biāo)識 docker每次重啟可能從機都需要修改
log_bin =mysql-bin
relay-log = relay-mysql #開啟二進制日志
relay-log-index =relay-mysql.index #開啟中繼日志
log_slave_updates=on
auto-increment-increment = 2
auto-increment-offset = 1 #從1開始 或者2開始 為避免id沖突 兩臺主機的起步要不同
在主機從機添加互訪同步賬號 分別執(zhí)行
GRANT REPLICATION SLAVE ON . to 'slave'@'%' identified by '000000';
分別執(zhí)行
stop slave;
reset master;
reset slave;
show master status;
主機執(zhí)行
change master to master_host='172.31.0.5',master_port=3306,master_user='slave',master_password='000000',master_log_file='mariadb-slave-bin.000001',master_log_pos=336;
從機執(zhí)行
change master to master_host='172.31.0.2',master_port=3306,master_user='slave',master_password='000000',master_log_file='mariadb-master-bin.000001',master_log_pos=337;
分別執(zhí)行
