编译安装：make & make install
启动、停止nginx：
cd /usr/local/nginx/sbin/
./nginx
./nginx -s stop
./nginx -s quit
./nginx -s reload
启动时报80端口被占用:
解决办法：1、安装net-tool 包：yum install net-tools

启动redies: service redis start
停止redies: service redis stop
查看redies状态：service redis status
查看进程：ps -ef | grep redis
设置redis为开机自动启动：chkconfig redis on
进入本机redis：redis-cli
列出所有key：keys *
编辑redies.conf文件
vim /etc/redis.conf
port 6379 //设置端口号
repuirepass zkfr2017 //设置密码
//运行远程连接
注释bind 127.0.0.1
protected-mode no
service redis_6379 start
./redis-server /home/server/redis-5.0.5/redis.conf //使用配置文件启动
redis-5.0.5/src/ redis-server redis-cli
使用端口登录：redis-cli -h 127.0.0.1 -p 6379
停止redies: shutdown
查看进程：ps -ef | grep redis
1、检测是否有安装redis-cli和redis-server;
[root@localhost bin]# whereis redis-cli
redis-cli: /usr/bin/redis-cli
[root@localhost bin]# whereis redis-server
redis-server: /usr/bin/redis-server

查看版本：cd bin
./ffmpeg -version安装mysql
按照依赖关系依次安装rpm包 依赖关系依次为common→libs→client→server
rpm -ivh mysql-community-common-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.22-1.el7.x86_64.rpm
rpm -qpl mysql-community-server-5.7.22-1.el7.x86_64.rpm
上面各个包安装完毕后，在 /etc/下生成 my.cnf 文件 和 my.cnf.d 文件夹
在/var/lib/下生成三个文件夹：mysql、mysql-file、mysql-keyring
在/var/log/ 下生成 mysqld.log 文件
在/var/run/ 下生成 mysqld 目录
systemctl start mysqld.service 启动mysql
systemctl status mysqld.service 查看mysql状态
systemctl stop mysqld.service 关闭mysql
查看mysql进程 ps -ef|grep mysql
查看3306端口 netstat -anop|grep 3306
grep 'temporary password' /var/log/mysqld.log 查看安装root密码
修改密码：mysql -uroot –p 命令使用随机密码登录mysql
set password for root@localhost=password('ZkFr@2017');
设置root用户权限,允许mysql远程连接
mysql> use mysql ;
mysql> select user,host from user;
mysql> show grants;
mysql> update user set host='%' where user='root';
mysql> flush privileges;刷新权限
修改数据文件路径
mv /var/lib/mysql /mnt/
ln -s /mnt/mysql /var/lib/mysql
vim /etc/my.cnf
datadir=/mnt/mysql
socket=/mnt/mysql/mysql.sock
修改mysql.cnf文件：
~#~ For advice on how to change settings please see
http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[client]
default_character_set = utf8mb4
[mysql]
default_character_set = utf8mb4
[mysqld]
port=3308
character_set_client_handshake = FALSE
character_set_server = utf8mb4
collation_server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'
wait_timeout=2880000
interactive_timeout = 2880000
max_allowed_packet = 100M
Remove leading # and set to the amount of RAM for the most important data
cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
innodb_buffer_pool_size = 128M
#
Remove leading # to turn on a very important data integrity option: logging
changes to the binary log between backups.
log_bin
#
Remove leading # to set options mainly useful for reporting servers.
The server defaults are faster for transactions and fast SELECTs.
Adjust sizes as needed, experiment to find the optimal values.
join_buffer_size = 128M
sort_buffer_size = 2M
read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
查看mysql端口号：netstat -anop|grep 3306
登录mysql：mysql -uroot –p
mysql> show global variables like ‘port’;
阿里云安装：
执行如下命令，更新YUM源。
rpm -Uvh http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
2. 执行如下命令，安装MySQL：yum -y install mysql-community-server –nogpgcheck
查看MySQL版本号：mysql –V
启动MySQL服务：systemctl start mysqld
设置MySQL服务开机自启动：systemctl enable mysqld
查看/var/log/mysqld.log文件，获取root用户的初始密码。
grep 'temporary password' /var/log/mysqld.log
使用root用户登录数据库：mysql -uroot –p
修改MySQL的root用户的初始密码：
set global validate_password_policy=0; #修改密码安全策略为低（只校验密码长度，至少8位）。
ALTER USER 'root'@'localhost' IDENTIFIED BY '12345678';
授予root用户远程管理权限：
GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '12345678';
test 的数据库备份到当前目录的 test.sql：mysqldump -uroot -p test >test.sql
test.sql 导入数据库：mysql -uroot -p -Dtest<test.sql
还有一种导入方法：输入命令：mysql -uroot -p12345678 ，进入 MySQL 数据库。输入 use test; ，连接数据库 test ，输入 source /root/test.sql; ，将 test.sql 导入数据库 test ，全部出现 Query OK ，则表示数据库导入成功
MySQL安全性配置。
执行如下命令，对MySQL进行安全性配置:mysql_secure_installation
