redis 多实例

// 复制默认的配置文件以创建新的配置
cp /etc/redis.conf /etc/redis_6380.conf
cp /etc/redis.conf /etc/redis_6381.conf
cp /etc/redis.conf /etc/redis_6382.conf

// 打开新的配置文件进行编辑（对应修改）
vim /etc/redis_6380.conf

# 修改以下几处：
port 6380
pidfile /var/run/redis_6380.pid
daemonize yes
logfile /var/log/redis/redis_6380.log
dbfilename dump_6380.rdb
dir /var/lib/redis
requirepass "xxxxxx"

// 启动 redis 实例
/usr/bin/redis-server /etc/redis_6380.conf –supervised systemd
/usr/bin/redis-server /etc/redis_6381.conf –supervised systemd
/usr/bin/redis-server /etc/redis_6382.conf –supervised systemd

// 关闭 redis 实例
/usr/bin/redis-cli -p 6380 -a gp123456 shutdown
/usr/bin/redis-cli -p 6381 -a gp123456 shutdown
/usr/bin/redis-cli -p 6382 -a gp123456 shutdown

mysql 多实例

// 创建每个实例对应的目录
mkdir -p /data/mysql/3307
mkdir -p /data/mysql/3308
mkdir -p /data/mysql/3309

// 目录所属修改到 MariaDB 用户与用户组
chown -R mysql:mysql /data/mysql/3307
chown -R mysql:mysql /data/mysql/3308
chown -R mysql:mysql /data/mysql/3309

// 初始化数据目录
mysql_install_db –datadir=/data/mysql/3307/data –basedir=/usr –user=mysql
mysql_install_db –datadir=/data/mysql/3308/data –basedir=/usr –user=mysql
mysql_install_db –datadir=/data/mysql/3309/data –basedir=/usr –user=mysql

// MariaDB 配置文件
vim /etc/my.cnf

# 添加一下配置
[mysqld_multi]
mysqld     = /usr/bin/mysqld_safe
mysqladmin = /usr/bin/mysqladmin
user       = root
pass       = password

[mysqld3307]
socket     = /data/mysql/3307/mariadb.sock
port       = 3307
pid-file   = /data/mysql/3307/mariadb.pid
datadir    = /data/mysql/3307/data
user       = mysql

[mysqld3308]
socket     = /data/mysql/3308/mariadb.sock
port       = 3308
pid-file   = /data/mysql/3308/mariadb.pid
datadir    = /data/mysql/3308/data
user       = mysql

[mysqld3309]
socket     = /data/mysql/3309/mariadb.sock
port       = 3309
pid-file   = /data/mysql/3309/mariadb.pid
datadir    = /data/mysql/3309/data
user       = mysql

// 启动
mysqld_multi start 3307-3309

// 初始化配置密码设置成 password
mysql_secure_installation -S /data/mysql/3307/mariadb.sock
mysql_secure_installation -S /data/mysql/3308/mariadb.sock
mysql_secure_installation -S /data/mysql/3309/mariadb.sock

// 停止
mysqld_multi stop 3307-3309

运维-yum安裝php56, php73, php74, php80多版本共存

发表于 2023-07-08 | | 阅读次数:

yum安裝php56, php73, php74, php80多版本共存

1.安装epel：

// 查看已安装的PHP，查到后rpm -e 卸载
yum list installed | grep php
yum repolist all | grep php 
yum install epel-release -y

2.安装REMI源：

1	rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/remi/enterprise/remi-release-7.rpm

3.查看可以安装的PHP版本：(54-80版本都有)

yum repolist all | grep php

// 安裝 php56 版本
yum install php56 php56-php-fpm php56-php-cli php56-php-bcmath php56-php-gd php56-php-json php56-php-mbstring php56-php-mcrypt php56-php-mysqlnd php56-php-opcache php56-php-pdo php56-php-pecl-crypto php56-php-pecl-mcrypt php56-php-soap php56-php-pecl-zip php56-php-process php56-php-pecl-yaf php56-php-xml php56-php-pecl-swoole4 php56-php-ldap php56-php-pear php56-php-xml php56-php-pecl-imagick php56-php-pecl-wddx

// 安裝 php73 版本
yum install php73 php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-soap php73-php-pecl-zip php73-php-process php73-php-pecl-yaf php73-php-xml php73-php-pecl-swoole4 php73-php-ldap php73-php-pear php73-php-xml php73-php-pecl-imagick php73-php-pecl-wddx

// 安裝 php74 版本
yum install php74 php74-php-fpm php74-php-cli php74-php-bcmath php74-php-gd php74-php-json php74-php-mbstring php74-php-mcrypt php74-php-mysqlnd php74-php-opcache php74-php-pdo php74-php-pecl-crypto php74-php-pecl-mcrypt php74-php-soap php74-php-pecl-zip php74-php-process php74-php-pecl-yaf php74-php-xml php74-php-pecl-swoole4 php74-php-ldap php74-php-pear php74-php-xml php74-php-pecl-imagick php74-php-pecl-wddx

// 安裝 php80 版本
yum install php80 php80-php-fpm php80-php-cli php80-php-bcmath php80-php-gd php80-php-json php80-php-mbstring php80-php-mcrypt php80-php-mysqlnd php80-php-opcache php80-php-pdo php80-php-pecl-crypto php80-php-pecl-mcrypt php80-php-soap php80-php-pecl-zip php80-php-process php80-php-pecl-yaf php80-php-xml php80-php-pecl-swoole4 php80-php-ldap php80-php-pear php80-php-xml php80-php-pecl-imagick php80-php-pecl-wddx

// 安裝 php81 版本
yum install php81 php81-php-fpm php81-php-cli php81-php-bcmath php81-php-gd php81-php-json php81-php-mbstring php81-php-mcrypt php81-php-mysqlnd php81-php-opcache php81-php-pdo php81-php-pecl-crypto php81-php-pecl-mcrypt php81-php-soap php81-php-pecl-zip php81-php-process php81-php-pecl-yaf php81-php-xml php81-php-pecl-swoole4 php81-php-ldap php81-php-pear php81-php-xml php81-php-pecl-imagick php81-php-pecl-wddx

3-1.卸载PHP版本

// 卸载安装包
yum remove php56 php56-php-fpm php56-php-cli php56-php-bcmath php56-php-gd php56-php-json php56-php-mbstring php56-php-mcrypt php56-php-mysqlnd php56-php-opcache php56-php-pdo php56-php-pecl-crypto php56-php-pecl-mcrypt php56-php-soap php56-php-pecl-zip php56-php-process php56-php-pecl-yaf php56-php-xml php56-php-pecl-swoole4 php56-php-ldap php56-php-pear php56-php-xml php56-php-pecl-imagick php56-php-pecl-wddx

// 查看rpm包
rpm -qa|grep php56
// 删除rpm包
rpm -e php56-runtime-5.6-1.el7.remi.x86_64

ls -al /opt/remi/
ls -al /etc/opt/remi/

启动服务
安裝好之後爲了PHP版本能夠共存還需要更改不同的php版本端口

// 在路徑下能夠找到相應的版本

1	ls /etc/opt/remi/

// 修改 php.ini 配置
vim /etc/opt/remi/php73/php.ini

# 开启整站 zlib 压缩输出
zlib.output_compression = Off
# 修改 zlib 压缩比
zlib.output_compression_level = 5
# 关闭 PATH_INFO

vim /etc/opt/remi/php74/php.ini

# 开启整站 zlib 压缩输出
zlib.output_compression = Off
# 修改 zlib 压缩比
zlib.output_compression_level = 5
# 关闭 PATH_INFO
cgi.fix_pathinfo = 0
# 设置时区
date.timezone = Asia/Shanghai

vim /etc/opt/remi/php80/php.ini

# 开启整站 zlib 压缩输出
zlib.output_compression = Off
# 修改 zlib 压缩比
zlib.output_compression_level = 5
# 关闭 PATH_INFO
cgi.fix_pathinfo = 0
# 设置时区

ik 带有两个分词器
ik_max_word ：会将文本做最细粒度的拆分；尽可能多的拆分出词语
ik_smart：会做最粗粒度的拆分；已被分出的词语将不会再次被其它词语占有
