宝塔设置全局PHP
装有宝塔的服务器，运行命令

ln -svf /www/server/php/74/bin/php /usr/bin/php


宝塔新增全局

查看当前是没有swap的

 

```bash
$ free -m

​       total    used    free   shared  buffers   cached

Mem:      498    310    187     0     17    170

-/+ buffers/cache:    122    375

Swap:      0     0     0




$ sudo df -hT

Filesystem   Type  Size Used Avail Use% Mounted on

/dev/xvda1   ext4  20G 3.7G  16G 20% /

tmpfs     tmpfs 250M   0 250M  0% /dev/shm
```



 



 

我们将swap挂载到/var下

 

$ sudo dd if=/dev/zero of=/var/swap bs=1M count=2048

2048+0 records in

2048+0 records out

2147483648 bytes (2.1 GB) copied, 47.8375 s, 44.9 MB/s

 

 

$ sudo mkswap /var/swap

 

$ sudo chmod 0600 /var/swap

 

$ sudo swapon /var/swap

 

挂载完毕后，查看内存使用情况。发现swap出现了。

 

[root@iZ23zvh0w6mZ lnmp1.1-full]# free -m

​       total    used    free   shared  buffers   cached

Mem:      498    456     41     0     10    100

-/+ buffers/cache:    346    152

Swap:     2047     0    2047

 

 

ok，swap已经可以使用了，接下来我们要将swap开机自动挂载。

编辑/etc/fstab文件

 

$ sudo vi /etc/fstab

因为阿里云默认是不让用户使用swap的（貌似现在的系统模版更新了，这一行新装系统都没有了，如果没有请忽略此步。）。

编辑/etc/rc.d/rc.local文件，将文件中的swapoff行注释或删掉。

 

$ sudo vi /etc/rc.d/rc.local 

\#!/bin/sh

\# This script will be executed *after* all the other init scripts.

\# want to do the full Sys V style init stuff.

 

touch /var/lock/subsys/local

ulimit -SHn 65535

\#swapoff -a //加上"#"号注释掉或者直接删除

ecs添加swap

wget -N --no-check-certificate "https://raw.githubusercontent.com/chiakge/Linux-NetSpeed/master/tcp.sh" && chmod +x tcp.sh && ./tcp.sh


wget -O tcpx.sh "https://git.io/JYxKU" && chmod +x tcpx.sh && ./tcpx.sh
